2.3 TYPICAL RISKS IN CRUSHING PLANT WORKING ENVIRONMENT
– sharp edges – high-pressure hydraulic equipment – electrical equipment – automatic functions and unexpected start-ups – toxic and corroding agents – machine inertia – hot surfaces and fires – zinc
Even though every Metso Minerals machine is designed with many safety features, it is impossible to design out all safety risks. There are potential hazards, that must be recognized and avoided. Noise levels may interfere with normal discussion when the machine is operating. By their nature, Crushing Plant and auxiliary equipment can create dust. Crushing itself and some other machine processes may momentarily obstruct the view of some machine parts. In general, high levels of respirable silica and other dust in the air may expose Operator to health risks for lung disease depending upon the length and amount of exposure and type of material being crushed. In addition, there are some risks or hazards which cannot be completely guarded or avoided because of interference with machine operations. Accordingly, working on the Crushing Plant requires constant alertness by all personnel in the area. Accidents happen unexpectedly. Below are some typical hazards and types of accidents that everyone working at, on or around the Crushing Plant should be aware of.
– conveyor belts – dust – noise and vibration – improper work methods – rotating equipment and moving components – ejection of material from the crusher – falling material from conveyors, and from loading, unloading and feeding operations – crushing cavity These typical hazards are discussed more fully in Section 2.3.1 of this chapter. Be aware of these hazards. All personnel working on or around the machine should be properly trained in avoiding these hazards. Typical Injury Types
Typical Hazards
– crushing – slipping, tripping and bumping – falling
– nips, gaps, and pinch points
– cutting
– poor housekeeping
– entanglement
– elevated or narrow working areas
– burns and electrical shocks
– lifting and shifting heavy loads
– respitary organ illnesses
– cranes and mobile cranes
– asphyxiation

2.3.1 Typical Hazards
ladders and floors. Tidiness provides a safer working environment by preventing or helping reduce tripping, slipping, fire hazards and electrical shocks.
Nips, Gaps, and Pinch Points
Elevated or Narrow Working Location
An ingoing nip is formed by drive devices such as belt and pulley, chain and sprocket or gears. Similarly, a pinch point may be formed by rotating or moving equipment. DANGER:
Nips and gaps are serious hazards in a Crushing Plant. They are usually guarded by nip guards, railings, or location. In all cases, extreme care must be taken to avoid nips, gaps, and pinch points or serious injury or even death may occur.
Crushing Plants are tall structures. The walkways and platforms, designed to be used during machine operation, are furnished with railings to help prevent falling. When working on an elevated surface be aware of machine movements and other activities in the area. Do not run on the walkways. Do not reach over or beyond walkway railings while the machine is running. Do not stand on railings or toe plates.
Poor Housekeeping
There may be narrow access routes for maintenance purposes. Do not use these routes while the machine is operating. Do not enter any close quarters within the Crushing Plant when the machine is operating. Promote good housekeeping. Keep machine environment, walkways, platforms etc. clean and dry and free of debris. Oily or wet machine environment, walkways, platforms, steps and hand rails are slippery. In cold weather, watch out for ice and snow. Wet spots, especially near electrical equipment, are dangerous. Return tools to their proper place after use. Even then extreme caution should be used. Follow established Crushing Plant safety procedures. Clean slippery deposits from walkways,

Lifting And Shifting Heavy Loads IMPORTANT!
•
When using a crane, always operate within the rated capacity of the crane. The safe rated capacity includes weight of hook, block and any materials handling devices such as cables, slings, spreader bars, etc. Subtract the weight of all these items from the rated capacity to find the true weight of the load that can be handled safely. Always follow the crane manufacturer's operational and safety instructions.
Cranes
Crushing Plants, like any other type of mechanical equipment, require regular periodic maintenance. One of the most flagrant Crushing Plant safety violations is the use of inadequate and unsafe lifting equipment. Although a Crushing Plant is a finely tuned piece of equipment, the internal parts of a Crushing Plant should be assembled and disassembled with crane facilities that have the capability of gently and slowly lifting and lowering the various parts that make up a Crushing Plant. Do not use chain hoists (chain blocks) to assemble or disassemble a Crushing Plant. These lifting devices lack the stability and robustness required in lifting and positioning heavy components. Do not use impact hammer boom or any other equipment which are not designed for lifting, for assembly or disassembly purposes. Affix the load securely to its destination. Never detach a lifting device from a load until the load is stable and secured from unintended movement. When it comes to safety, don't compromise!
IMPORTANT!
The weight indicated in machine plates tells the weight of standard configuration. In many cases the actual weight may differ greatly from that indicated in machine plate due to, e.g., options or ancillary equipment. Always verify the weight of the object you are lifting before attempting to lift it.
•
Mobile cranes
Safe ratings are based on operating the crane on firm, level ground; outriggers must be properly extended and/or lowered whenever required. Avoid fast swings, hoists or sudden braking; these can cause overloads. Do not handle large, heavy loads in strong winds. When moving your crane, check bridges before crossing, make sure they will support the total weight in question. Check clearances under bridges for overhead electrical lines and any overhead obstruction. Be sure your hitcher is clear before starting lift. Make sure the load is securely attached. IMPORTANT!
When using a mobile crane, always operate within the rated capacity of the machine to avoid buckling the boom or tipping.

Sharp Edges Take the following precautions when lifting heavy loads: – Follow all established Crushing Plant procedures. – Follow all instructions and safety procedures recommended by the crane manufacturer. – Plan the lifting and maintenance procedures in advance. Read and understand specific instructions for proper use of lifting equipment prior to using (e.g instructions of the machine, lifting device and local regulations).
Sharp edges may occur on any metal structures. Equipment damage may uncover or produce unexpected sharp edges. Sharp edges may inflict deep and serious cuts. Wear protective gloves when handling materials, parts, etc. with sharp edges. Repair or guard detected sharp edges immediately.
– Clean the working environment beforehand to prevent slipping and tripping hazards.
High-pressure Equipment - Hydraulic or Air
– Make sure that the crane and other lifting devices such as chains and slings have sufficient capacity and are in good working order. – Do not attempt to ride or sit on moving loads. – Be sure that crane operators, riggers and other personnel have been properly trained. – Rig the load firmly to prevent any unintened movement and assure stable and accurate positioning. – Make sure nobody is below or on the path of the load and that the transfer routes are clear and proper protective clothing and gear are used.
High pressure oil can be dangerous. Relieve all pressure before opening or removing any hydraulic or air pressure lines, valves, fittings, etc. Do not touch pressurized components since the pressure from a pin hole leak is so strong that it can easily penetrate the skin or eyes. Always exercise caution when handling hydraulic devices. Regularly check the condition of hoses, pipes, valves and various connections. Replace them as necessary. Before starting any maintenance work, stop all hydraulic pumps, lock out pump motors, and depressurize the system, bringing all components to a zero energy state. Remember to also depressurize the accumulators through

Bleed the hydraulic system regularly to remove entrapped air that may interfere with normal expected machine operation or cause a hazard during maintenance. WARNING!
Poorly tightened or damaged hydraulic components may inject dangerous jets of fluid. Before restarting the machine, be sure that the hydraulic system is ready for operation, and personnel are clear of affected areas. WARNING!
Electrical Equipment
Be especially cautious when working with or near electrical equipment. An electric shock can be fatal. Crushing Plant electrical outlets must be grounded and have ground fault interruption protection. Tools plugged into the outlets must be double insulated. Never expose electrical equipment to mechanical damage or humidity. Protect all electrical equipment from direct contact with water or high humidity. Protect electrical devices that move as part of the machine from dirt and mechanical damage. Regularly check the operability of these devices.
Machine parts may move unintentionally and cause a risk of injury. Before restarting the machine, make sure that all personnel are clear of affected areas where machine movement may occur.
DANGER:
There is a risk of an electric shock, if sufficient precautions are not taken. An electric shock can be fatal. For maintenance work, disconnect all devices from electric and hydraulic power sources and follow Crushing Plant lockout procedures.
The lockout program, locks, tags and the blocking/restraining devices provided are designed for your protection. Your responsibility is to follow the program and use the proper equipment. Remember: – Follow procedures. – Stay alert. – Do not take anything for granted. – Verify lockout. – Each person working on the unit must have his own lock with only 1 key.

Welding Equipment IMPORTANT!
All maintenance personnel who use cutting and/or welding torches should be advised if there are hydraulic components in the immediate area in which they are working.
IMPORTANT!
Weld repairs are to be performed only by qualified personnel. Welders and welder’s helpers must wear protective clothing and equipment. Precautions must be taken when torch cutting and/or welding due to the health hazards posed by many metals. Anyone performing these types of procedures should avoid breathing the fumes. Such procedures should be done outdoors or in a well ventilated area with either a separate clean air supply provided to the mechanic or with local exhaust of fumes. Please refer to EU, OSHA, MSHA or other applicable standards as appropriate. One of the most frequently used tools around the Crushing Plant is the cutting torch. Crushing Plants which are equipped with hydraulic components and/or conveyor belts and/or v-belts should have these components depressurized and adequately covered with flame-proof material so that sparks, weld spatter, etc., cannot reach theses areas. Ruptured high pressure hydraulic lines will quickly vaporize the hydraulic fluid as it reaches the atmosphere. This vaporized fluid can quickly become a mass of flames, resulting in severe burns for personnel in the immediate area. Adequate precautions should be made to avoid contact with these components. Never perform welding or torch cutting activities in the presence of flammable materials. WARNING:
Risk of injury. Fire may break out. Never perform welding or torch cutting activities in the presence of flammable materials.
09/2005
Contact Metso Minerals or its authorized representative prior to any welding of major Crushing Plant components such as main frame, adjustment ring, bowl, etc. Performing welding on the Crushing Plant components can be detrimental. Before welding, always verify that material is weldable! Failure to do so may result in weldment failure and present a risk of injury and/or property damage.
Toxic, Corroding and Irritating Agents
Before handling chemicals, carefully read the safety instructions from the supplier of the respective chemical. Hazardous chemicals may be in use. Wear protective clothing, gloves, boots, glasses, and respirator when necessary. Refer to the MSDS (Material Safety Data Sheets) and Crushing Plant procedures for handling of these materials. Avoid prolonged contact with fluids, such as gasoline, diesel fuel, hydraulic oil and cleaning solvents, which may cause skin irritation or other reactions.

METSO MINERALS SAFETY INSTRUCTIONS 2-13
SECTION 2 - GENERAL SAFETY INSTRUCTIONS
Machine Inertia
Due to the large inertial forces of the Crushing Plant and Crushing Plant components, the machine can not be stopped abruptly. This is potentially hazardous to personnel. All personnel must stay clear of rotating elements and other moving parts until the machine has come to a complete stop. Regularly inspect the structural elements to maintain safe operation. Hot Surfaces and Fires
There are hot surfaces on Crushing Plants. Protective gloves and coveralls help protect against burns. Be aware of hydraulic system, hoses, fittings, and pipes. Regularly inspect and observe high temperature lines, and fluid lines for leaks or damage. On mobile equipment be cautious around the engine because of exhaust gases.
In case of a fire, the machine must be equipped with a fire extinguisher or fire extinguishing system, and marked according to the regulations. Legislation and regulations about suitable equipment may vary by country. Familiarize yourself with applicable standards. Personnel must also be trained properly to be able to use fire extinquishing equipment. A trained person with sufficient fire extinguishing equipment must be present during welding maintenance work. Cold water on hot metal surfaces may cause a violent explosion. Monitoring after welding must be arranged as required by laws and regulations. If no other regulations apply, monitoring time is a minimum of one half hour. Fire Hazards
When in contact with hot temperatures, or when heated themselves, some hydraulic oils may ignite at around 392°F (200°C). Attention must be paid to the condition of hydraulic hoses and couplings. Remove immediately oil spills from floor, walkways, and pits. Fix all sources of oil leaks and clean up spills.
– Do not smoke while refueling, or when handling fuel containers. – Shut off engine when refueling and use extra caution if engine is hot. – When pouring fuel into the tank, ground the funnel or spout against the filler neck to avoid static electric spark.

completely eliminated the possibility of workers being accidentally burned due to molten zinc either spilling or exploding when it comes in contact with wet surfaces. When epoxy backings are used, care should also be taken when removing the liners with a cutting torch . Do not use molten zinc as backing material. Use epoxy only according to specific instructions from the manufacturer. Conveyor Belts
– Never use an open flame to check fuel, battery electrolyte or coolant levels, or to look for hydraulic leaks anywhere on the equipment. Use a flashlight. Know where fire extinguishers are kept, how they operate, and for what type of fire. Check regularly, at least monthly, to be sure they are in the working area. – Do not weld or cause open flame in the presence of flammable materials.
WARNING:
Do not use conveyor belts as walkways. Do not climb on them. Always stay clear of any falling or dropping materials or components. Never attempt to stand on, walk on, or step across a conveyor. Never stand below a running conveyor. Do not use loose clothing, neck ties, necklaces or other loose items when near conveyors or other moving or rotating equipment. Emergency pull cords should be used only in case of emergency -do not use them for routine stoppage of conveyor. Never attempt to service the conveyor while it is energized. Keep in mind hazardous nip points.
– In the event of a fire, shut down the Crushing Plant, hydraulic power unit and lubrication system if this can be safely done. Warn other people in the area and commence fire fighting activities according to applicable rules. It is the responsibility of the Owner to maintain proper training and instructions in these respects. Epoxy Versus Zinc

Crushing Plant Dust IMPORTANT!
Metso Minerals highly recommends that dust protective devices such as an appropriate respirator be worn by anyone exposed to airborne dust to prevent its inhalation.
WARNING:
By their nature, Crushing Plant and auxiliary equipment such as chutes, transfer stations, screens, etc. can create dust and, if not contained, the dust can escape into the air. In general, high levels of dust (particularly, respirable silica) in the air can create a hazard of lung disease, depending upon the concentrations of dust, the length of exposure, and the type of material being crushed. Dust protective devices and dust warnings may be required by OSHA, MSHA or local laws.
Breathing dust may be hazardous to the health of anyone working at, on, or around the Crushing Plant. It can cause serious or fatal respiratory diseases including silicosis! It is the responsibility of the Owner and Operator to determine the necessity and adequacy of protective devices and warnings, to provide them, and to ensure that they are used and followed!
The Owner and Operator of the Crushing Plant must identify the material being crushed and ascertain whether respirable dust from the application poses a health hazard to personnel in the vicinity of the Crushing Plant.If the material presents such a hazard the Owner and Operator must take all necessary measures to ensure that personnel are protected from the dust. Such measures include, but are not limited to providing dust collection system, using water spray bars at the feed and discharge points, crusher transfer points and screens and providing adequate personal respiratory protection devices to workers. Crushing with a choke level may also reduce the amount of dust issuing from the Crushing Plant itself. Because the configuration of each rock crushing installation is different, Metso Minerals recommends that the Owner and Operator consult Metso Minerals or a dust consultant about possible alternative means of dust reduction.

Noise and Vibration
is an increased risk of falling on a vibrating platform. Avoid standing on a vibrating Operator's platform or walkway. Unexpected or excessive vibrations may be a sign of wear and/or maintenance needs. Excessive vibrations associated with a portable crushing or screening plant is frequently caused by improper cribbing.
•
Crushing Plant Noise
Crushing Plant by its very nature is noisy and the auxiliary equipment found at, on or around the Crushing Plant such as chutes, transfer stations, screens, etc., can at times be noisier than the Crushing Plant itself. Typical Crushing Plant noise level while crushing range from 100 - 110 dB measured at 1 m (3ft) from the Crushing Plant.
It is recommeded to regularly monitor vibration levels of machine components including, but not limited to: – bearings – shafts – rollers – structural members (including conveyor frames, walkways, platforms, hoppers, chutes, etc.)
Metso Minerals recommends wearing ear protection at, on and around Crushing Plant, particularly when the noise level exceeds 85dB. It is recommended that the Owner develop a signaling communication system in noisy environments to reduce the risk of accidents. Proper machine maintenance and replacement of worn parts can help reduce noise. The most commonly applied noise reduction procedures are: – use of isolation techniques – equipment enclosures – operator enclosures – silencers Allowable noise levels and exposure limits are regulated by various agencies such as ISO, OSHA, MSHA, etc. Refer to applicable safety regulations for permissible noise exposures, and take steps to ensure compliance with those regulations. •

Improper Work Methods
typically checked with a tachometer. Make sure that any access openings have a protective cover in place at all times except when RPM readings are being taken. Never change sheave combinations without first consulting your Metso Minerals representative. Ejection of Objects from the Crushing Plant
Improper work methods and motions may cause physical injuries. Use suitable tools, cranes or jacks for moving large and heavy objects. Overreaching and improper support for loads may lead to injuries to the back or other parts of the body. If you are unsure of proper work methods, contact your safety director or other person responsible for ensuring the safety at your work place.
Ejected objects from the Crushing Plant may cause bodily injury. For example rock can be thrown several meters (several yards) into the air out of the crushing cavity during operation. Ejected materials may include rock, tramp metal, metal rods and work implements. Do not look into crushing cavity while crusher is in operation. Never attempt to clear jam on feeder, crushing cavity or conveyors when system is energized.
When lifting equipment by hand, protect your back by lifting close to your body and using your legs without twisting. Use hoists whenever possible. Stand clear of hoisted loads and lifting cables. Rotating Equipment and Moving Components
Rotating and moving components provide pinch points, snagging possibilities and other potential hazards. Keep clear of all moving parts until they come to a complete stop. Do not use any body part, tool or other foreign object to attempt to stop, adjust, clear, or clean any area in proximity to moving equipment such as vibrating feeder, conveyor belts, drives or other rotating parts of the crusher. Engaging in such activities can result in severe personal injury, including death. Crushers, designed to operate within a specific RPM range for maximum efficiency, are

2.3.2 Typical Injury Types
Falling Material from Conveyors, Loading, Unloading and Feeding Operations
Crushing In general, avoid areas where you may be exposed to expected or unexpected machine movements. Crushing injuries typically occur either between two rotating or moving parts, or between a moving component and a stationary object.
Rocks or other objects may fall from conveyors during loading, unloading and feeding operations. Impact of falling material may cause serious bodily injury. To assure safe operation, all personnel must be alert when operating or working at or around the machine. Wear proper protective clothing (including also helmet) and protective devices. Keep all non-operating and non-trained personnel clear of the Crushing Plant at all times.
Keep all body parts, clothing and tools away from areas where they may get trapped, pinched, or crushed, or otherwise come into contact with moving parts on the Crushing Plant. When moving equipment, be sure the path is clear. Horns and lights, where provided, are for your safety to alert you of moving objects. Pay attention to all such devices. Slipping, Tripping, and Bumping
Never walk under any equipment included in loading, feeding, crushing, conveying, discharging or stockpiling material.
Items such as hoses, tools, etc., on walkways and Crushing Plant floors impede movement and create a tripping and slipping hazard. Good housekeeping reduces the risks considerably. Personnel should wear safety shoes that reduce the risk of slipping and provide protection against falling objects or crushing. Hydraulic oil leaked or spilled on the floor must be cleaned up immediately. To help avoid injury, be aware of parts positioned close to the floor level or protruding machine components, changes in elevation of platforms, walkways, and narrow access points. It is recommended that safety shoes be worn at all times. Wear safety helmets and other safety equipment as appropriate.

The location of local E-stop buttons may vary on different machines; therefore the locations of these buttons must be verified from the operating and maintenance manuals specific to the equipment and/or from proper training.
3.1.1 Overview
The machine system has many built-in safety features. Owners and Operators should make themselves familiar with the function and purpose of each feature and make sure all of the features are enabled. Owners and Operators should never attempt to defeat, bypass or disable any safety features. If any of the features are defeated or become disabled, the machine should not be operated until corrective action is taken and all safety features are restored.
In emergency stop situations, the objective is to stop the machine as soon as possible to minimize potential injuries while maintaining the structural integrity of the machine. CAUTION:
Emergency stop not only stops the machine but often it may initiate other protective sequences.
3.1.2 Emergency-Stop (E-Stop)
NOTE: It may be necessary to engage
reset switches before movement can resume. 3.1.3 Safety Interlocks
Use the emergency stop when injury may occur or human life is in danger from continued operation of the machine. This provides the quickest, most sure way to stop the machine. Due to the large inertial forces of the Crushing Plant and Crushing Plant parts and components, the machine can not be stopped abruptly. Large red emergency stop buttons are typically located in control panels near the vicinity of danger points. Emergency stops can be, and often are, in the form of pull cords that run paraller to conveyors and surround hazards. WARNING:
On large complex systems, the E-stop may control only those components that are in the immediate area.
09/2005
A safety interlock is a device that will interrupt the supply of electricity, hydraulic oil or compressed air to an actuator or motor. A machine already in operation may need to stop quickly due to Operator error, safety violations, or an unexpected machine event. For example, a safety gate may be interlocked to stop a machine if the gate is opened while the machine is running. Interlocks can also be used to prevent sudden unexpected movement of a machine function or component. During operation, the logic system (i.e. programmable logic controller, microcontroller, relay system or similar device) controls the functions of the machine. Interlocks built into the system employ limit switches and other sensors to help assure proper machine operation.
EN REV-A
METSO MINERALS SAFETY INSTRUCTIONS 3-1
SECTION 3 - MACHINE SAFETY
The pilot-controlled throttle valve helps prevent uncontrolled actuator movements.
THEREFORE IT IS IMPORTANT THAT INTERLOCKING ARRANGEMENTS ARE NOT REMOVED, MODIFIED OR BYPASSED, AND THAT THEY ARE CORRECTLY ADJUSTED. LIMIT SWITCHES, AND OTHER SENSORS MUST BE KEPT IN GOOD WORKING ORDER.
Pressure transducers monitor the system pressure for information or control purposes. Safety Gates
Electric Motors
Some safety gates are designed so that opening or closing of the gates will prevent or stop a specific machine function in that area. Hydraulic, hydraulic or electric limit interlock switches may cut off the drive or actuator power or initiate an emergency stop mode.
Electric drives and motors may be controlled to stop or reduce speeds, as determined by the safety interlocks at a particular location. Hydraulic System
For specific operation, see later sections of this manual. WARNING:
Components that help protect the hydraulic system include certain valves, such as hose burst valves, pressure relief valves, counterbalance valves and pilot-controlled throttle valves as well as pressure transducers and drain valves for pressure accumulators. Metso Minerals uses these components where applicable in the hydraulic systems to minimize the potential for hazardous situations to occur. A hose break valve functions to lock up if fluid flow is discharged too rapidly from an actuating cylinder, as happens if a hose breaks and the loads react to gravity. The pressure relief valve prevents the system pressure from rising beyond system capabilities. It helps protect the entire fluid system and any operators in the vicinity from bursting hoses and components.

METSO MINERALS SAFETY INSTRUCTIONS
Safety gates must not be opened during normal machine operation. Exceptions to this rule are defined in the operating instructions.
Safety gates may also be opened for maintenance purposes when the machine has been stopped. Follow all lockout procedures. Cable Switches
Cables or ropes connected to the electrical switches can be used as interlocks also. They may stop machine function in areas where control panels cannot be closely located but where Operators may be working . Know the locations of e-stop pull cords for conveyors.

3.1.4 Additional Warning Devices
Horns and Lights
If visual contact between work places is obstructed or if communication is difficult, sound and/or light signaling devices may be used before starting the machine or a machine function. The warning device for start-up should operate so that personnel are given sufficient time to move to a safe distance from the machine. It is the responsibility of the Owner to ensure that the Crushing Plant is always equipped with required horns and lights. Safety Signs and Labels
3.1.5 Walkways, Service Platforms, Ladders And Railings
The design of walkways, ladders and railings follow standards and regulations for the application. The walkways provide access to the machine. Safe operating procedures must be followed when on walkways. Never stand, walk or climb in or on any area of the Crushing Plant not designated for such activity. If an area of the Crushing Plant must be accessed and cannot be reached by designated walkways, ladders, or platforms, then the Owner and Operator must make all necessary arrangements for safe access to the area, including but not limited to safe lifting devices and fall protection. CAUTION:
Extreme caution must always be used on machine walkways.
Safety signs have colors to determine the degree of hazard in particular areas. These signs must not be removed. Temporary placement of safety signs and danger tags should also be used on the control panels to warn of maintenance work and lockout situations. Obey all warning and safety signs on the machine and in the manual. Safety Warning Colors Color of safety warnings are typically safety yellow.

4.2.2 Fire Safety During Maintenance And Repair
– Protect yourself and others from sparks with proper personal protective equipment and clothing.
4.2.3 Preventive Maintenance
Observe all regulations on fire safety. Sources for fires include, but are not limited to the following: – sparks from grinding – flames and molten metal from welding or torching – electrical arcing – spontaneous combustion – smoking. Before starting any work take the following steps to prevent a fire hazard:
Preventive maintenance will both increase safety and be economically beneficial. It is more safe and economical to replace a worn part during a scheduled shut-down than to repair a broken device in the middle of a production cycle. A machine or device that is not in proper condition, and that has been left without regular maintenance and inspections, is a safety risk for its user. For instance, without lubrication a bearing may fail, bringing a production line down. Furthermore, the hot bearing may present a fire hazard or cause skin burns. Some preventive maintenance suggestions for a machine include:
– Properly dispose of rags with combustible material to avoid spontaneous combustion.
– observing the maintenance and lubrication instructions of the machine and equipment suppliers
– Move flammable materials 10 m (33 ft) or more away from any fire hazard.
– keeping the machine and surrounding area clean and orderly
– Clean up all oil spills and leaks.
– monitoring the vibration levels of the machine and to help predict bearing failures
– Remove any source of flammable gases, liquids or solids.
– monitoring the power consumption of motors to help detect early failures
– Use proper electrical grounding techniques for welding.
– repairing all leaks as soon as possible to prevent more serious conditions that eventually may occur
– Clean up all debris.
– Provide adequate fire extinguishing equipment; inspect such fire equipment regularly. – Arrange for qualified personnel to guard against fire while welding, cutting, or heating operations are being performed, as well as a sufficient period of time after the work is completed.

– Be sure all control power supplies are turned off, disconnected, and lock out procedures have been followed.
4.3.2 Electrical Fault Situations
– Confirm that ALL power sources are disconnected. Some electrical devices may be supplied by more than one power source.
Diagnostics are provided through pilot lights, alarms, and help messages.
Electrical faults may be caused by component failures such as loose or damaged wiring.
IMPORTANT!
– Be aware that multiple voltage levels may exist in some junction boxes. – Ensure that during lockout procedures, locks and signs are appropriately attached, and subsequently removed only by the person who installed them after all work is completed. Follow Crushing Plant lockout instructions for placement and removal. – For testing and troubleshooting, clear all personnel from the machine just as though the machine were being returned to production mode. Reactivate the necessary power supplies and perform the tests. Then again disconnect all power supplies and follow lockout instructions before further maintenance work is performed. – Be sure electrical supply voltage is disconnected before drilling into any structural frame members. Electrical cables may be inside.
Electrical connections can and do loosen due to vibration in transit and thermal expansion of the wires and lugs in operation. This is especially trua after initial delivery, break in and after major relocation. Loose connections increase current draw, which can result in false trips, intermittent circuits, and burned-out components. As part of the start-up, check and retighten as necessary all electrical connections in the elctrical enclosure. Repeat after the first forty to fifty hours of operation. This work must be performed by properly trained personnel.
IMPORTANT!
Improper phasing will damage backstops in conveyor drive reducers and may damage hydraulic system components.
– Verify that electric motors are disconnected before starting any maintenance work, thereby preventing the supply of electricity to the motor. Generally the disconnects are located in the drive control room. Each person performing maintenance work should install their lock and sign the lockout tag.

WARNING:
– Mineral and other oils and additives can cause skin irritation. Inhaled oil mist can also cause internal irritation, headache or nausea. Avoid repeated exposure to these materials. Use appropriate personal protective equipment.
Risk of personal injury due to high pressure fluid jets. Do not check for pressurized leaks with bare hands. Use cardboard or other appropriate techniques.
– Purge entrapped air from the hydraulic system. Entrapped air in the hydraulic system can cause erratic and unexpected movements. – Oil mist in the work area or oil leaking onto floors and walkways will cause a serious risk of slipping. Clean up all spills and repair leaks immediately.
Hydraulic hoses are subject to wear and tear. Pressurized hoses tend to straighten up, bend or twist due to reaction forces. Replace all weakened or deteriorated hoses promptly. Keep hoses properly clamped and secured to help prevent being whipped by broken hoses.
– Hydraulic oil temperature may be extremely high;
– When changing a cylinder, or other hydraulic device, plug all open ports and hose ends. Catch spilled oil in a suitable storage device and avoid introducing dirt into the system. Dispose of all waste fluids as presented by law.
WARNING:
Elevated temperatures levels can be hazardous and may cause severe burns. Wait until machine cools down before doing maintenance or repair.
– Tighten disconnected pipe and hose couplings immediately after reinstallation. Before finishing the work, check all parts and connections that have been serviced or repaired.
– A mixture of air and oil mist may explode at higher temperatures. Hydraulic oil spilled on hot machine surfaces may start a fire. – Pressurized hydraulic hoses should not be handled with bare hands since high-pressure leaks may easily penetrate the skin. Hydraulic fluid pressure in the hoses may exceed 3000 PSI/210 bar/21MPa.

3.2 DIESEL ENGINE The operating power of the LT106 is generated from the Caterpillar diesel engine. The engine runs the hydraulic pumps.
3.3 TRACKS The LT106 moves with tracks. The tracks ensure safe and fast movements of the machine even in the rough terrain.
3.4 CRUSHER The Lokotrack C106 jaw crusher is the heart of the LT106. The crusher crushes the feed material into smaller pieces.
3.5 FEEDER The feeder ensures even and continuous material flow into the crusher. The feed material smaller than the opening of the feeder grizzly goes through the grizzlies passing the crusher. This increases the capacity and prevents material packing in the crusher.
3.6 MAIN CONVEYOR The main conveyor transfers the crushed material from the crusher to the stock pile or to the next process.
3.7 SIDE CONVEYOR (OPTIONAL) The optional side conveyor transfers the material that has passed the crusher through feeder grizzlies to the stock pile beside the machine.
3.8 MAGNETIC SEPARATOR (OPTIONAL) The optional magnetic separator is installed above the main conveyor. It separates magnetic objects from the crushed material and transfers those to a separate pile beside the machine.

CHAPTER 5 - OPERATION
5.4.7 Crusher speed selection NOTE: The feeder starts automatically when the process is started and stops when the process is stopped. If the hydraulic temperature of the unit is extremely cold (-5oC/23oF), the system will ask to carry out a cold start of the process. The feeder will not start until the temperature of the oil has reached a certain temperature.
The IC system of the Lokotrack controls the crusher speed. The crusher can run either on target speed or with a stabile fixed speed.
5.4.7.1 Target speed When the target speed is set on the IC system, the crusher tries to maintain the desired speed value by adjusting the control current to the crusher pump. Refer to the IC system manual for more details.
When the process is running and the feeder is in automatic mode, the IC controller adjusts the feeder speed according to the crusher and other device operations in the LT. The IC controller tries to keep the best and equal material flow to the crusher to prevent overfilling.
5.4.7.2 Stabile fixed speed When the target speed function is disabled the fixed control current can be used to drive the crusher. With this way of control, the IC system keeps the control current stabile all the time. Therefore it does not effect to the increasing and decreasing loads, which alter the speed of the crusher.
5.4.8 Feed control The feeder can be stopped and restarted again during the crushing process. The “feeder start” and “stop” buttons are located in the remote control box on the service platform. If the machine is equipped with a radio control feature (optional), the feeder can be started and stopped using the radio control feature. To stop and restart the feeder do the following: 1. Stop the feeder during the crushing process by pressing the "feeder stop" button. 2. Restart the feeder after it has stopped completely by pressing the "feeder start" button.
In order to stabilise the feed rate, the feeder always starts at minimum speed regardless of the speed setting. After a while the speed changes to the set value. In order to control the capacity, the feeder speed can be adjusted using the feeder speed +/- switch, but only in feeder manual mode. The switch is located in the control box on the service platform. The speed can also be adjusted by using the optional radio controller. NOTE: When the process is running, the automatic control controls the stopping of the feeder. The feeder will stop if the speed of the crusher decreases or the level indicator (optional) of the crusher indicates an alarm. NOTE: If the feeder speed is too high, stones may fall over the flanks of the hopper. NOTE: Radio control will by-pass the feeder controls located in the remote control box on the service platform. The best capacity can be reached by having the feeder remain running for as long as possible. An overfilled feeder will reduce the capacity and cause unnecessary wear.

CHAPTER 5 - OPERATION
5.4.8.1 Feeder Automatic Control The feeder control mode can be either manual or automatic. The selection is done in the feeder parameter F5. Refer to the IC Instruction Manual for the parameter change. If manual speed is selected, feeder speed is controlled by a remote control housing or radio control. If the crusher operation pressure or speed exceeds the preset alarm values, feeder speed will automatically be reduced in prior to stop. It is recommended to use manual speed when the unit is followed with a secondary stage crushing or a screen. Feed rate does not fluctuate as much as with automatic feeder speed. It is recommended to use automatic feeder speed when material throughput fluctuation does not interfere the following process, eg. recycling. With automatic feeder speed the throughput of the crusher can be maximized.
5.4.10 Clearing of the jammed main conveyor NOTE: Never try to clear the blockage with excavator. If the conveyor stops, follow these instructions: –
Stop the process immediately.
–
Clear the jammed main conveyor as well as possible. When most of the material is removed, the main conveyor can be started by using a manual lever in the hydraulic valve manifold.
NOTE: Do NOT use this method if the rock is too big to pass under the magnetic separator! Use the hook to remove iron bars and wires. Be very careful not to hurt yourself. Never use hook when the machine is running.
5.4.8.2 Feed Material Refer to the C-Jaw instruction manual for the feed material.
5.4.9 Crusher setting The crusher setting is the most important crusher parameter since it determines the crusher's capacity as well as the top size of the crusher product. It is therefore indispensable for everyone to understand how the crusher setting is measured.
5.4.11 Removal of the steel Always stop the machine (feeder, crusher, conveyors and engine) before removing metal from it. Make sure that the machine can not be started when removing metal from it.
Refer to the C-Jaw instruction manual for setting measurement

5.4.12 Crushing site The unit should be located near the material pile to make loading easy and quick. Shape the feed material pile with a wheel loader or excavator so that it is distributed over a small area and piled high enough for easy loading (fig. 5.25).
The place where the crusher is to be located must be even. The machine must not be allowed to sway. The surface below the crusher must be levelled and evened out. Spread some fine-grained material on the ground, distributing it evenly (fig. 5.27). Next, harden the underlying ground by driving the unit back and forth over the site (fig. 5.28).
Figure 5.25 First shape the material pile
The location of the discharge pile must be chosen so that it doesn't cause any danger to workers or passers-by. Make sure that there is enough space for the discharge pile, the discharge machinery (wheel loader or excavator) and the lorry (fig. 5.26).

5.4.13 Feeding measures
If the feed material contains metals, someone should stand next to the feeder and remove the metal pieces before they are able to enter the crusher.
5.4.13.1 Loading Equipment The unit can be loaded with the help of either an excavator or a wheel loader.
• •
LOADING USING AN EXCAVATOR
The unit can be loaded from the side or the rear. Find a suitable loading site and move the excavator bucket to its loading position. Then drive the unit into a suitable position below the excavator bucket. The operator of the excavator must have full visibility to the upper part of the feeder (fig. 5.32).
LOADING USING A WHEEL LOADER
The unit can only be loaded from the rear. The maximum bucket width is 2400 mm (95") for standard-size hoppers. In the case of 6 m3 hoppers, the maximum bucket width is 3200 mm (126"). If required, use the feed material to make a loading ramp to ease access to the feeder. Drive the unit as close to the pile as possible to make loading quick and easy. NOTE: The feeder has two basic applications: a. stabilising the feed rate b. separating the fine material before it enters the jaw crusher. If the feeder is too full, it will not separate the fine material, which in turn will result in decreased operating capacity. NOTE: Do not drive the excavator bucket into the material or try to force the material into the jaw cavity.
Figure 5.32 The operator of the excavator must have full visibility to the upper part of the feeder.
NOTE: Keep feed gate closed during operation.
Load the material into the rear end of the feeder, on top of the solid base (fig. 5.33). WARNING! When the impactor crusher is fed from rear, the crusher rotor might shoot the feed material directly backwards if e.g. the protective chains / rubbers are worn.

MOVING AND TRANSPORTING
CHAPTER
6
6.1 GENERAL Because of the size and weight of the equipment, special attention must be paid when moving the LT. Always make sure that nobody is on top of or near the LT. Use always approved lifting equipment with adequate capacity when preparing for a transport.
IMPORTANT! The hydraulic oil temperature must be observed during longer moves. The temperature may be a maximum of 90 °C. Oil that is too hot might damage the sealings.
WARNING!
NOTE!
Make sure that the lighting is appropriate at the site or near the LT.
Longer moves (more than 100 m) must be driven with the feeder end of the machine first, when the driving gear comes after the track. In that case, the lower end of the track remains tight, because the ground supports the track and it does not bend down. This helps to prevent the chain from jumping over the driving wheel teeth.
MAXIMUM INCLINATIONS Sideways 5° Lengthwise 15 °
NOTE! WARNING! Make sure that there is nobody on top of or near the LT.
When driving on a sloping surface or onto a trailer truck, the automation may stop the LT if the hydraulic fluid or the coolant level is too low. If the machine stops unexpectedly, check the fluid levels.
IMPORTANT! NOTE!
Make sure that –
the driving route is smooth enough
–
differences in altitude or inclinations do not prevent driving
The track drive does not function if the selector switch of the hydraulic functions has been switched ON.
WARNING! In case the surface is slippery or icy, make sure that the sanding is sufficient enough to prevent the unpredictable movement of the LT.

Engine speed idle...1200 1200...1900 1900...
7. In the case the ground is soft , drive the tracks backwards and forwards few times in order to make the ground more compact before placing the LT on a new crushing site. 8. If you do not proceed with crushing after moving the machine, shut down the engine as instructed in section 5. NOTE! When the radio control use is switched on, you cannot use the cable drive control box.
6.2.1 Some hints for turning the LT: –
the LT turns easier when driven forward with the minimum power required.
–
the LT turns easier on hard than soft ground.
–
If the LT cannot be turned when driving uphill, drive a short way downhill and turn the unit at the same time.
–
By driving the center of one of the track onto a small rise, rock, or similar, it becomes easier to turn towards the lifted side.
–
Always select an appropriate surface for turning the LT. Only attempt to turn the LT in a location where the turning is easiest.
–
When turning on soft ground, change the direction gradually.
–
Avoid turning the unit completely at one time, so that material does not accumulate on the sides of the tracks.
IMPORTANT! If driving on uneven ground or with the LT connected to Lokolinks, you have to exercise special caution when driving the unit. Always note the ground clearance of the machine and the irregularities of the ground. IMPORTANT! Avoid turning the machine in situations when the traction force is on the upper section of the chain track. The chain track may loosen as the tension spring inside the track frame cannot hold the pressure any longer, which might cause the track chain to jump over the sprocket.

CRUSHING
CHAPTER
7
7.1 CRUSHING LOCATION The LT106 should be located near the material pile to make loading easy and fast. Shape the feed material pile with the wheel loader or excavator so that it is in small area and high enough for easy loading (Figure 7.1). The location of the discharge pile must be chosen so that it doesn't cause any danger to workers or passers-by. Ensure that there is enough space for the discharge pile, discharge machinery (a wheel loader or excavator) and a lorry (Figure 7.2).
Figure 7.3 Spread some fine material on the ground, then rub it smooth.
Figure 7.1 First shape the material pile
Figure 7.2 General measures taken on the site.
07/07
The location where the crusher is to be placed must be even. The machine must not be allowed to sway. The surface below the crusher must be levelled and evened out. Spread some fine-grained material on the ground, distributing it evenly (Figure 7.3). Next, harden the underlying ground by driving the LT106 back and forth over the site (Figure 7.4).

7.2 FEEDING MEASURES LOADING EQUIPMENT The LT106 can be loaded with the help of either an excavator or a wheel loader. LOADING USING AN EXCAVATOR The LT106 can be loaded from the side or the rear. Find a suitable loading site and move the excavator bucket to its loading position. Then drive the LT106 into a suitable position below the excavator bucket. The operator of the excavator must have full visibility to the upper part of the feeder (Figure 7.8). Load the material into the rear end of the feeder, on top of the solid base (Figure 7.9).
Figure 7.8 The operator of the excavator must have full visibility to the upper part of the feeder.
If the feed material contains metals, someone should stand next to the feeder and remove the metal pieces before they are able to enter the crusher. LOADING USING A WHEEL LOADER The LT106 can only be loaded from the rear. Maximum bucket width is 3200 mm (126"). If required, use the feed material to make a loading ramp to ease access to the feeder. Drive the LT106 as close to the pile as possible to make loading quick and easy. NOTE: The feeder has two basic applications: stabilising the feed rate and separating the fine material before it enters the jaw crusher. If the feeder is too full, it will not separate the fine material, which in turn will result in decreased operating capacity.
Figure 7.9 Load the material into the rear end of the feeder on top of the solid base.
CAUTION! Do not hit the excavator bucket into the material or try to force the material into the jaw cavity.

CHAPTER 7 - CRUSHING
NOTE: A lifting instrument, such as a rope or chain, that is used to lift a single side wall, will not be strong enough to lift the entire LT106 unit.
Turn up the side walls of the feed hopper and lock them in place with the help of the wedges (Figure 7.13).
When the side wall is lifted vertically against the joint hinge, the mass of the entire LT106 may apply to the lifting instrument.
Figure 7.13 Turn up the side walls of the feed hopper. NOTE: Do not stand in side of the frame when mounting the wedge on it's place
If the additional side walls of the unit are not lifted with hydraulic cylinders, be extremely careful when lifting or lowering them. In this case, the side walls must be lifted and lowered using a crane. WARNING! Make sure that there is no-one below the side walls, or too near them, as it may cause an accident risk.
When lifting the side walls, first lift the side wall to its uppermost position with the crane (phase 1) and position the wedges. When positioning the wedges, the crane must not make any corrective measures. If the wedge cannot be fitted in its place, the mechanic must move away from the side wall and give new instructions to the crane attendant. After this, place the wedge first at the crusher end (phase 2) and then at the feeding end (phase 3). Once the wedges are fitted in their positions, make sure that they are tightly in their positions by hammering them. Finally, secure them with screws or chains. Lifting or lowering the side walls must in no circumstances be done with the help of an excavator. The order of lifting the walls: first, lift both side walls, then the back side wall. After lifting the back side wall, position and lock its wedge as well. To lower the walls, perform the steps above in reverse order. Before removing the wedges, first set and tighten the lifting ropes of the crane. Do not perform any corrective measures during the operation. NOTE: If the side walls are lifted with the help of a hydraulic cylinder, they are lifted in the same order as explained above. Lift and lock one side wall at a time, as explained above. When positioning the wedges, do not lift or lower anything.

Before starting the crushing process, always make sure that the crusher cavity is empty. If there is material on the cavity, clear the cavity as instructed in Chapter 7.8 .
WARNING!
When the crushing process has started, the RPM speed of the diesel engine cannot be adjusted by the operator before the crushing process has been stopped again. Initiate the crushing process by pressing “Process ON” -button (ref 4.1 and 4.2) NOTE: When starting the crushing process, the automatic control function takes care of starting the devices, delays, monitoring any possible problems and adjusting the RPM level of the diesel engine. The initiation of the crushing process takes about one minute after the process button has been pressed. –
Connect the water supply (if needed).
–
Turn on the lights if required.
In case of emergency press the "Emergency stop"-button to stop the LT106. Do not attempt to crush stones that are too large to fit inside the cavity. Having to reposition rocks wastes time, reduces capacity, and imposes unnecessary loads on the crusher. You can stop the feeder and crusher in order to safely remove uncrushable objects from the feeder. Both the crusher and the feeder can be restarted from the remote control box located in the service platform. CAUTION! Clay, wood and any non-stone-based materials must be prevented from entering the crusher. This may overload and damage the crusher. Also make sure that no explosives are allowed to enter the crusher.
Stop the crushing process by pressing the "Process OFF” -button. NOTE: When stopping the crushing process, the automatic control function takes care of turning off the equipment, delays, monitoring any possible problems and adjusting the RPM level of the diesel engine. The termination of the crushing process takes approximately 1 minute. 1. Process options eg. side conveyor, magnet separator or hydraulic PTO must be selected before the process start. Process options are editable during the process. 2. You can stop the feeder and crusher in order to safely remove uncrushable objects from the feeder. Crusher and feeder can be restarted from the service platform. Load some material into the feed hopper while the vibrating chute is running. For further instructions, refer to Chapter 7.6 . When loading with the help of a wheel loader, the feed hopper must be almost empty before any more material can be loaded into it. When loading with the help of an excavator, more than one bucketful can be loaded in to the hopper at a time.

If the machine is equipped with a radio control feature (optional), the feeder can be started and stopped using the radio control feature.
The best capacity can be reached by having the feeder remain running for as long as possible.
To stop and restart the feeder do the following: 1. Stop the feeder during the crushing process by pressing the "feeder stop" button. 2. Restart the feeder after it has stopped completely by pressing the "feeder start" button. NOTE: The feeder starts automatically when the process is started and stops when the process is stopped. If the hydraulic temperature of the unit is extremely cold (10oC/14oF), the system will ask to carry out a cold start of the process. The feeder will not start until the temperature of the oil has reached a certain temperature. In order to stabilise the feed rate, the feeder always starts at minimum speed regardless of the speed setting. After a while the speed changes to the set value. In order to control the capacity, the feeder speed can be adjusted using the crusher speed +/-switch. The switch is located in the control box on the service platform. NOTE: When the process is running, the automatic control takes care of stopping of restarting the feeder. The feeder will stop if the speed of the crusher decreases or the level indicator (optional) of the crusher indicates an alarm. DANGER! If the feeder speed is too high, stones may fall over the flanks of the hopper.
NOTE: Radio control will by-pass the feeder controls located in the control box on the service platform.

CHAPTER 7 - CRUSHING
7.8 CLEARING OF THE BLOCKAGE CAUTION! Never try to clear the blockage with an excavator. If the process is initiated with material in the cavity, the crusher tries to start with slow ramp and if the rock is strong enough to prevent crusher from starting, the alarm # 3 (“Crusher pressure rising too fast on start”) will be shown in the display. The process will be fully activated but the feeder and the crusher will not function. You can swing the crusher clockwise and counter clockwise with the buttons 8 and 9 (Figure 7.23) of the remote control box, located on the service platform. When the cavity is clear, switch on the crusher using the “Crusher start” -button (# 7, Figure 7.23). Start the feeder. Figure 7.23 Remote control
7.9 REMOVAL OF THE STEEL WARNING! Always stop the machine (feeder, crusher, conveyors and engine) before removing metal from it. Make sure that it can not be started during removing metal from it.
WARNING! Use a hook to remove iron bars and wires. Be very careful not to hurt yourself. Never use a hook when the machine is running.

CHAPTER 7 - CRUSHING
7.10 RECYCLING In carrying out recycling processes with the crusher, all metal objects should be removed from the feed before they enter the crusher.
The optional magnetic separator can be used for the removal of small metal objects. The maximum diameter allowance for steel objects entering the crusher is 20 mm. The maximum length allowance is 0,5m.
The most efficient method is to prepare the feed material for the process and remove all the metal pieces from it before loading it to the LT106. Someone should stand next to the feeder and remove the metal pieces. Be very careful when touching the feed material. The feeder must be stopped when removing larger objects. Never climb on top of the feeder.
Figure 7.24 Removal of metal objects during the crushing of recyclable materials.
7.11 OPTIONAL EQUIPMENT LEVEL INDICATOR
INTERMEDIATE CABLE FOR SECONDARY UNIT
The purpose of the level indicator is to control the feed material level that enters the crusher. The indicator stops the feed process and emits a light signal when the material level is too high. The indicator resets itself automatically.
The LT106 unit is equipped with a 6-pin socket allowing information flow between the primary and the secondary unit. The socket has three different functions:
Keep the level indicator clean to ensure that it functions proper function.
Pins 1&2: When connected, LT106 gets information on the connection of the secondary unit..
Refer to the IC500 Instruction Manual for further information on switching the level indicator to ON or OFF position. HYDRAULIC OUTPUT
Pins 3&4: Feeder ON/OFF information (secondary feed/emergency functions can be connected to this). Normally open contact required. Pins 5&6: For the level sensor of the secondary unit. Normally closed contact required.
The hydraulic output can be set ON/OFF permanently or ON with the process. Refer to the IC500 Instruction Manual for further information on how to select the hydraulic output.

SERVICE INSTRUCTIONS
CHAPTER
10.1 GENERAL Only skilled and experienced mechanics must be allowed to service the plant. In any work related to the operation, adaptation to manufacture, conversion or adjustment of the LT and its safety equipment, as well as to inspection, maintenance and repair, observe starting and stopping procedures in accordance with the Instruction Manual and any indications relating to maintenance work! Secure extensively, as far as necessary, the area of maintenance works! In case the LT is completely switched off during maintenance and repair works, it must be safeguarded against unexpected switching-on. Lock-up main starting equipment, draw off keys and affix a hazard pictorial at the main switch. Smoking and any open flame is prohibited in the immediate area of the machine when refuelling or servicing the fuel system.
10
Service facilities must be kept clean. Oil and water can make floors slippery and highly dangerous. Avoid severely soiled clothing, they can be a fire hazard. Keep the LT and equipment free from oil spillage and dust. A clean machine reduces the fire risk and simplifies visual checks for components requiring attention. Be careful when using pressure cleaning equipment. Even low pressures and temperatures can damage wire insulation. Check wiring for signs of abrasion damage or kinks. This can cause short circuits and fire. Check hydraulic hoses for abrasion damage or kinks. Never weld or grind containers of inflammable liquids. Always have a fire extinguisher on hand when carrying out welding or grinding operations. Notify the location and use of fire extinguishers.
IMPORTANT!
10.2 BATTERY MAINTENANCE
In case of fire:
10.2.1 Fluid level check
–
Move the LT away from the dangerous area
–
Stop the engine
–
Turn off the main switch
–
Start fire fighting and give the alarm if necessary.
The fluid level in the batteries must be checked every 100 operating hours (figure 10.2.1). The level should be approximately 10 mm(1/4") above the plates. Add clean distilled water as required. Monitoring the fluid consumption will give an indication of the charge of the battery, but a separate test of the specific gravity of the acid will confirm the state of charge. If the fluid consumption is high it is possible for the alternator charging rate to be too high.
Diesel fuel is flammable - do not use as cleaning fluid. Use solvents of accepted quality only. Always stop the engine during maintenance unless it is mentioned in the instruction manual to keep the engine running. Do not check for leaks with a bare hand, use suitable cleaning cloth. Never adjust any hydraulic valve beyond the pressure recommended by the manufacturer. Always ensure adequate ventilation when running the engine in a confined area. Remember that some solvent qualities may cause skin irritation and may be extremely inflammable. Avoid breathing of solvent fumes.

Figure 10.2.1 Check battery fluid level every 100 operating hours. Add clean distilled water in the accumulator as required
LOKOTRACK LT106 INSTRUCTION MANUAL
10-1
CHAPTER 10 - SERVICE INSTRUCTIONS
10.2.2 Battery check
10.2.3 Cleaning batteries, terminals and cables
The level of charge in the battery must be checked regularly using a hydrometer. Do not make this check immediately after adding any distilled water to the battery; the water and acid will be more evenly mixed after some charging has taken place. The specific gravity of a fully charged battery is approximately 1.28, and if only half-charged the reading will be about 1.2. These values relate to a battery temperature around +20ºC(68ºF).
Batteries and terminals must be cleaned at least once per year. The terminals and the cable ends should be cleaned with the special tools which will restore the contact area to the right form and size. After cleaning, the terminals and cable ends should be liberally covered with petroleum jelly to protect against oxidation. Check also the fastening of: battery earth cables to the main frame, engine starter cables, and electrical connections for the alternator. Clean and tighten as necessary. Keep battery cases clean and dry.
Batteries must always be maintained as far as possible at full charge. If the charge is allowed to remain low, the plates will become sulphated reducing the capacity and efficiency of the whole battery. Remember that a half-charged battery will freeze at a temperature of -25ºC(-13ºF) and a flat one at only -10ºC(14ºF).
10.3 OTHER ELECTRICAL EQUIPMENT 10.3.1 Charging circuit
Never use an open flame when checking the acid level of a battery. The gases given off by the chemical reaction during the recharging process are highly inflammable. The liquid used in lead-acid batteries is dilute sulf acid. This acid is corrosive, will cause severe burns to exposed skin and will damage clothing. Be very careful when handling a battery.
–
Check and tighten connections regularly.
–
The alternator requires only periodic attention.
NOTE: It is important to strictly follow the instructions for protecting the alternator: –
Do not remove battery cables or any other connections in the charging circuit while the engine is running.
–
Never start the engine if any wire in the charging circuit is disconnected or loose.
–
Whenever the batteries are charged using an external source, the earth lead to the frame must be disconnected from the battery. When reconnecting batteries, using jumper leads or a charger, be sure to identify the correct polarities.
–
Always disconnect the batteries when servicing the electrical equipment of the LT.
–
Do not cause a short circuit in any part of the system, nor take a test reading with an instrument with low internal resistance.
Always wear protection glasses and gloves while handling and maintaining.
NOTE: If auxiliary batteries are used to assist engine start, make sure that:

–
batteries have the same voltage
–
the correct poles are connected

CHAPTER 10 - SERVICE INSTRUCTIONS
10.3.2 Starter circuit Normally the starter circuit requires little attention, but all components should be kept clean and electrical connections tight. The batteries are an essential part of the electrical system and are required to be kept fully charged, clean and topped up properly to maintain the acid level. Battery cables must also be checked for tightness and kept clean and greased.

10.4 WELDING
10.6 CRUSHER SPEED SENSOR
If any welding is to be done on the machine, care must be taken to protect sensitive electrical equipment.
FUNCTION
–
Stop the engine.
The crusher is equipped with a speed sensor. The sensor controls the pitman rotation and gives one impulse per one pitman revolution.
–
Turn the main switch OFF.
MOUNTING
–
Disconnect the earth lead to the batteries.
–
Fasten the earth cable of the welding apparatus as close to the part to be welded, as possible and make sure that no welding current is able to pass through any bearings or electrical equipment.
The sensor is mounted at the back side of the pitman, close to the eccentric shaft. To locate the sensor, lift the rubber cover behind the pitman.
–
Disconnect engine wire harness sockets.
–
Disconnect control module sockets.
10.5 PRESSURE ACCUMULATOR
The sensor is mounted on its support with a plastic clamp. The correct distance from the sensor end to the pitman is 3-5 mm. (The minimum distance while the crusher is running). When replacing the sensor there is no need to adjust the sensor itself. Sensor has a LED-indicator. The function can be controlled from this led indicator. Possible reasons if the speed sensor is causing an alarm:
NOTE: Before removing / repairing any components from the hydraulic setting control circuit release the pre-charge pressure by opening the SHUT off VALVE. Make sure that the pressure gauge above accumulator indicates NO pressure. Make sure that the security valve of the gauge is open.

2.1.1 General safety instructions
5. It is prohibited to stay in the danger area during the crushing process. The crushing material may be thrown into a few meters distance from the crusher. Always use helmet and safety glasses.
WARNING! Before performing any maintenance or repair work, make sure that the crusher is stopped and locked out.
6. Do not look into the jaw cavity during crushing. Material may be thrown from the crusher during crushing and cause injuries. Always use a helmet and safety glasses.
LOCKOUT PROCEDURE of the Lokotrack installed crushers
7. Because the crusher is installed on rubber dampers, it moves during crushing. This movement causes a crushing danger. Never put your hands or feet between the moving parts and the structure of the crusher during crushing. The movement may be as much as ± 10mm.
1. Switch off engine 2. Remove the ignition key and keep it on person during lockout 3. Place appropriate maintenance warning signs (TAG OUT)
8. Clearing a jammed cavity is extremely dangerous. Do not attempt to clear the cavity until the crusher has stopped completely.
LOCKOUT PROCEDURE of the electrical motor driven crushers
9. The crusher does not stop immediately after the motor has been turned off. Make sure that the crusher has stopped completely before opening any covers, performing any maintenance, or adjusting the crusher.
1. Switch off motor 2. Lock the main switch of the motor with a padlock or make sure in some other way that the engine cannot be started
10. The crushing plant and auxiliary equipment such as chutes, transfer stations, screens, etc. can create dust and, if not contained, the dust can escape into the air. Metso Minerals highly recommends that dust protective devices such as an appropriate respirator be worn by anyone exposed to airborne dust to prevent its inhalation. It is the responsibility of the Owner and Operator to determine the necessity and adequacy of protective devices and warnings, to provide them, and to ensure that they are used and followed!
3. Lock the main switch of the hydraulic adjustment power unit (if delivered) with padlock 4. Keep the keys on person during lockout 5. Place appropriate maintenance warning signs (TAG OUT). 1. Ignoring the safety instructions or the warning signs increases the risk of the severe injury or death.
11. The noise level is dangerously high near the crusher. All personnel working near the crusher must wear hearing protection. The noise level is typically about 102-110 dB next to the crusher during crushing.
2. Nordberg C series jaw crushers has been designed for safe operation when used by professional staff in the operating situations included in this instruction manual. All other service and repair procedures must be performed by specially trained personnel or authorized Metso service staff.

Feed: The raw material to be crushed, such as the rock type (limestone, basalt, granite, etc.) or man-made materials such as concrete and asphalt. The feed size is typically denoted in terms of a size distribution or based on an average top (maximum) size. Product size: The size of the material after it has been crushed. Similarly to the feed size, the product size is typically denoted in terms of a size
EN
distribution or based on an average top (maximum) size. Capacity: The output of the crusher in tons per hour. Feed Opening: The opening where the feed material is fed into the crusher. The feed opening has two dimensions: a width and a depth. The feed opening depth is a critical dimension because it dictates the maximum feed size a given jaw crusher model can accept.
140588-3_K
NORDBERG C SERIES INSTRUCTION MANUAL 3-1
CHAPTER 3 - GENERAL CRUSHER INFORMATION
Maximum Recommended Feed Size: As a general guideline, the maximum average recommended feed size should be about 80% of the feed opening depth. Such measures will ensure that any bridging events resulting from oversized feed are kept to a minimum. A rock hammer is recommended for applications where the maximum feed size is regularly close to the feed opening depth.

Nip Angle: The angle between the fixed and moving jaws. The nip angle is often referred to as the "bite" angle as well. Jaws: The members that perform the crushing are commonly referred to as jaws. The jaws consist of a stationary and moving jaw, and depending on the model each one of these may consist of either 1 or 2 pieces. Different jaw profiles are available for different applications. Discharge Setting: The shortest distance between the bottom of the fixed and moving jaws as measured at the point where the jaws are at their closest relationship during their work cycle (i.e. the closed side setting, or c.s.s.). The method in which the setting is measured varies depending on the jaw profile. These differences are explained in detail in the CRUSHER SETTING section.

CHAPTER 3 - GENERAL CRUSHER INFORMATION
3.7 CRUSHER SETTING The Crusher setting is the most important Crusher parameter since it determines the Crusher's capacity as well as the top size of the Crusher product. It is therefore indispensable for everyone to understand how the Crusher setting is measured. The discharge setting is the shortest distance between the bottoms of the fixed and moving jaws during their work cycle. This distance is referred to as the closed side setting (c.s.s.), and it is a calculated distance as the Crusher setting is typically measured when the Crusher is at rest. The largest distance between the bottoms of the fixed and moving jaws is referred to as the open side setting (o.s.s.), and it is typically a distance that is directly measured when the Crusher is at rest.
The Crusher setting is measured in three different ways, first referring to the tooth groove (bottom) or crown (top) of the stationary jaw and then to the tooth groove (bottom) or crown (top) of the movable jaw. Thus, the setting is always measured from the Stationary (bottom or top) to the Movable jaw (bottom or top). The three alternatives are shown in Table 3-3. The measurement type depends on the profile as well as on the Crusher model. This information is also found in the Crusher Spare Parts Book.

CHAPTER 3 - GENERAL CRUSHER INFORMATION
For example, the setting of the C125, equipped with Quarry jaws, is measured from Top to Top (Type 2). However, with Standard jaws, the setting is measured from Bottom to Top (Type 1). IMPORTANT! The Crusher setting must always be measured in a straight line at the bottom of the crushing cavity. Measure the setting always from the least worn area.
Example Crusher: C140 Stroke: 42 mm (15/8” ) (Table 3-4) Jaw Profile: Quarry (top to top) O.S.S.: 230 mm (9") C.S.S.: 230 – 42 = 188 mm (9" – 1 5/8" = 7 3/8")
It is easiest to measure the setting when the Crusher is at rest with a device such as a block of wood of known dimensions (several blocks should be available if more than one setting is typically used). The distance measured this way is larger than the closed side setting (c.s.s.) because the pitman always stops at its lowest point. This value is close (±2mm/±0.08") to the open side setting (o.s.s.). As previously mentioned, the closed side setting is calculated by deducting the stroke from the open side setting (Table 3-4).

CHAPTER 3 - GENERAL CRUSHER INFORMATION
Figure 3.6 Measuring the setting
NOTE: The C.S.S does not have to be calculated if the user knows the Crusher setting limits in terms of the O.S.S. The C.S.S. is typically calculated because Crusher capacity is always denoted in terms of the C.S.S. only.
3.8 CRUSHER SETTING LIMITS All C-Series Crusher models have a maximum possible setting as well as a minimum allowed setting, and it is very important that the user understands why these are important to keep these in mind at all times. The maximum possible setting is simply the maximum setting that the Crusher is physically able to accommodate. Typically, such setting is indicated with new jaws, and the setting actually depends on the jaw profile as well as on whether a spacer is being used or not. This information is always found in the Crusher Spare Parts Book.
3-10
NORDBERG C SERIES INSTRUCTION MANUAL
The minimum allowed setting (c.s.s. or o.s.s.) is the minimum setting at which the Crusher can be used when the Crusher is operated according to Metso Minerals' recommendations. The minimum allowed setting is very important as it takes into account the design and operation limits of the Crusher. Not respecting these recommendations can lead to a poor utilization of the jaws (high scrap rate) as well as a shortened Crusher life. The minimum allowed setting varies depending on whether the application is a normal rock application (Normal), or a recycling application (Special), when materials such as concrete, asphalt and bricks are being crushed. Note that the minimum allowed setting does not depend on the jaw profile (it is always the same for a specific Crusher model). See Table 3-5.

APPENDIX
NORDBERG C-SERIES JAW CRUSHER'S CHEEK PLATE LIFTING TOOL SAFETY, OPERATING AND MAINTENANCE INSTRUCTIONS
Load the lifting tool evenly and carry out the lifting and displacement of the cheek plate carefully. Keep the lifting zone free of people during lifting. Do not use the cheek plate lifting tool in a hurry.
1. Purpose of the cheek plate lifting tool The cheek plate lifting tool that is provided with Nordberg C Series jaw crushers is intended for the lifting of genuine Metso Minerals Nordberg C Series wear parts (cheek plates) only. The cheek plate lifting tool is not designed nor tested for the lifting of other types of objects.
4. Commissioning and operating conditions The cheek plate lifting tool is supplied fully assembled and it is ready for immediate use. The cheek plate lifting tool can be used in the same operating conditions as the jaw crusher.
2. Storage of the cheek plate lifting tool When not in use the cheek plate lifting tool should normally be stored carefully away from damaging materials, such as dirt or sand. They should not be left lying on the ground where they may be damaged. If it is likely that the cheek plate lifting tool will be out of use for some time they should be cleaned, dried and protected from corrosion, e.g. lightly oiled. 3. Safe use WARNING! Before lifting any wear parts, check the weight of the component and ensure that the lifting equipment being used is adequate to lift the weight. Read all instructions concerning the cheek plate lifting tool carefully and make sure that the tool is inspected regularly. Prior to lifting, make sure that the cheek plate lifting tool is locked and does not come out of the lifting hole. The cheek plate lifting tool is only meant for the lifting of genuine Metso Minerals Nordberg C Series cheek plates. It is neither designed nor tested for unfastening used cheek plates that may not readily come loose prior to lifting. Do not overload the cheek plate lifting tool. The maximum lifting load is found on the tag of the cheek plate lifting tool (see Table 1). Stop the lifting procedure immediately if the cheek plate is stuck to its location.

Table 1 The cheek plate lifting tool should be clean enough to observe possible damages.
6. The cheek plate lifting tool verification before first use and in service
Adequate lighting should be provided and the cheek plate lifting tool should be examined throughout its length to detect any evidence of wear, distortion, or external damage.
Before first use Before first use of the cheek plate lifting tool it should be ensured that: a. the cheek plate lifting tool is precisely as ordered;
7. Handling the load Preparation
b. the manufacturer's certificate is at hand; c. the identification and working load limit marking on the cheek plate lifting tool correspond to the information on the certificate;
Attention should be given to any specific instructions provided for the handling of the load. Before starting the lift, it should be ensured that the load is free to move and is not bolted down or otherwise obstructed.
d. full details of the cheek plate lifting tool are recorded.
Mass of the load It is essential that the mass of the load to be lifted is known. If the mass is not marked, the information should be obtained from the consignment notes, manuals, plans, etc. If such information is not available, the mass should be assessed by calculation.
Before each use Before each use the cheek plate lifting tool should be inspected for obvious damage or deterioration (see paragraph 8 Maintenance / Inspection). If faults are found during this inspection, the procedure given in paragraph 8 Maintenance should be followed.
Centre of gravity
The cheek plate lifting tool must be inspected visually before every lift and more precisely at least once a year. See detailed instructions below. Inspections must be documented for own as well as authority audits. A damaged cheek plate lifting tool must be replaced or repaired immediately. Special attention should be paid to the condition of the threads, welds, and fasteners.

CHEEK PLATE LIFTING TOOL
The position of the centre of gravity of the load should be established in relation to the possible points of attachment of the chain sling. To lift the load without tilting or toppling it, the following conditions should be met: a. For two leg chain slings the attachment points should be on either side of and above the centre of gravity. b. The hook to which the cheek plate lifting tool is attached should be directly above the centre of gravity.
N11456138_K
EN
APPENDIX B
Method of connection The cheek plate lifting tool is attached to the load and the lifting machine by means of terminal fittings such as hooks and links. Chains should not have any twists or knots. The lifting point should be seated well in the hook and the hook should be free to incline in any direction to avoid bending. For the same reason, the master link should be free to incline in any direction on the hook to which it is fitted. Straight leg
8. Maintenance Inspection During service, the cheek plate lifting tool is subjected to conditions which affect their safety. It is necessary therefore to ensure, as far as is reasonably practicable, that the chain sling should be safe for continued use. If the tag or label identifying the chain sling and its working load limit becomes detached and the necessary information is not marked on the master link itself, or by some other means, the cheek plate lifting tool should be withdrawn from service.
In this case the lower terminals are connected directly to the attachment points. The hooks and attachment points should be selected so that the load is carried in the seat of the hook and tip loading of the hook is avoided.
The chain sling should be withdrawn from service and referred to a competent person for thorough examination if any of the following are observed:
In order to prevent dangerous swaying of the load and to position it for loading, a tag line is recommended.
a. The chain sling markings (information on the chain sling identification and/or the working load limit) are illegible.
When loads are accelerated or decelerated suddenly, high dynamic forces occur that increase the stresses in the chain. Such situations, which should be avoided, arise from snatch or shock loading, e.g. from not taking up the slack chain before starting to lift or by the impact of stopping falling loads.
b. Distortion of the upper or lower terminals. c. Chain stretch.
Safety of lift Hands and other parts of the body should be kept away from the chain to prevent injury as the slack is taken up. When ready to lift, the slack should be taken up until the chain is taut. The load should be raised slightly and a check made that it is secure and assumes the position intended. This is especially important with basket or other loose hitches where friction retains the load. Landing the load The landing site should be prepared. It should be ensured that the ground or floor is of adequate strength to take the weight taking into account any voids, ducts, pipes, etc. which may be damaged or collapse. It should also be ensured that there is adequate access to the site and that it is clear of any unnecessary obstacles and people. It may be necessary to provide timber bearers or similar material to avoid trapping the chain sling or to
EN
protect the floor or load or to ensure the stability of the load when landed.
If the chain links are elongated or if there is any lack of free articulation between the links or noticeable difference in the leg length of multi-leg chain slings, the chain may have been stretched. d. Wear by contact with other objects usually occurs on the outside of the straight portions of the links where it is easily seen and measured. Wear between adjoining links is hidden. The chain should be slack and adjoining links rotated to expose the inner end of each link. Inter-link wear, as measured by taking the diameter indicated (d1) and one at right angles, (d2) may be tolerated until the mean of these diameters has been reduced to 90 % of the nominal diameter (dn) provided.

*(1(5$/ The operation manual deals with vibrating TK feeders and screens. Henceforth these will be generally called vibrating devices.
3.1 Used terms — Capacity = Transport ability of vibrator in tons per hour. — Sorting capacity = Sorting ability of vibrator in tons per hour. — Feeding end (F) = The end of the vibrator, where material is fed into. — Discharge end (D) = The end of the vibrator, where material is discharged from. — Vibrator = The mechanism in the vibrating device that makes the device vibrate. — Grizzly (G) = Grating structure in the vibrating device that separates the fine matter from the fed material. — Screen deck = Cloth structure in vibrating device that sorts the fed material into fractions. — Stroke length = Distance between vibration motion extreme positions of vibrating device. — Stroke angle = Direction of stroke movement in relation to horizontal.
3.2 Nordberg vibrating devices The Nordberg vibrating devices have either a closed bottom, or a screen deck and one or more grizzlies. There are different sizes of vibrating devices for various uses. The vibrating devices have either a direct squirrel-cage motor drive or a regulating drive with a frequency converter, some vibrating device types have a hydraulic drive. Grizzlies and screen cloths are available for different uses and they can be changed.

General
3.3 Uses of Nordberg vibrating devices The vibrating devices manufactured by Metso Minerals are used for feeding, transport and sorting of stone material, concrete and asphalt. 3.4 Principle of operation The body is supported on its base by springs, which the body vibrates on. Material is fed into the feeding end of the vibrating device and it is discharged from its discharge end.
The stroke angle of interconnected shafts is defined by the reciprocal position of the shafts and the position of the vibrator. The vibrating device can have a grizzly or a screen deck that lets the fine grain sizes through. The capacity (feeding efficiency) is regulated by altering the eccentric masses of the vibrator. The capacity can also be regulated by changing the speed of rotation of the vibrator by means of an optional frequency converter or a hydraulic drive, if needed.
Two identical rotating mechanisms revolving in opposite directions provide a rectilinear stroke movement. The material on the vibrating device moves due to the fact that the vertical movement of the base is quicker than that produced by the gravitational pull. Therefor the material comes off the bottom, continuing its movement in the direction of the movement of the moment of the base. The stroke angle of free synchronizing shafts is defined by the center of gravity and the position of the vibrator.

Screen cloths
The grizzlies can be changed and there is a choice of different types of grizzlies with different grizzly openings.
The cloth can be changed and there are cloths with different hole size.
There are three different types of grizzlies in figure 3.6.1. On the left is a plate grizzly, in the middle a rod grizzly and on the right a bar grizzly. Measure G is the grizzly opening at the end, which is mainly used to identify the grizzlies. The choice of the grizzly depends on the feed to be used and the required sorting limit, among others. Contact a Nordberg specialist when you want to choose a grizzly.
The choice of the cloth depends on the feed to be used, the required sorting limit and the purity requirements of the fractions, among others. Contact a Nordberg specialist when you want to choose a screen cloth. The tightening of the screen cloth is done with tightening bars, hook screws and wedges. The tension of the screen cloth always depends on the cloth properties. The biggest recommended cloth screen hole size is 50-60 mm.

,167$//$7,2123(5$7,21 $1'75$163257 4.1 Foundation The vibrating device is mounted on springs, and the spring fixing plates are installed onto a firm foundation. The mounting surfaces for the fixing plates have to be horizontal. Vertical springs have to be in vertical position. If the upper spring support is adjustable, verify that it is parallel to the lower fixing plate. See if the springs on both sides are compressed an equal amount, you will notice the distortion of the base from the compression. Spacer plates can be used underneath the fixing plates, if needed.
stroke movement of the vibrating device becomes vague decreasing the output. Observe that you also have to pay attention to the horizontal rigidity of the base. The support forces of the vibrating device can be found in the information related to each type. No undue parts may be fixed onto the body of the vibrating device, e.g. feeding funnels, chutes, etc. These have to be fixed onto their own support structures, apart from the vibrating device.
Figure 4.1.1 Straightness requirements of the vibrating device foundation Figure 4.1.1 shows the straightness requirements for the foundation. The spring bases of the vibrating device have to be on the same level with each other up to a precision of 10 mm. The supporting structures have to be placed directly below the springs. Verify that the lower structures of the vibrating device are not elastic. If the lower structure is elastic, the

Installation
The vibrating device should be installed in such a way that the distances between the vibrating device and other structures (e.g. supporting structures, funnels, chutes, silos), when loaded, are at least as follows. This relatively large free space between the body and other structures is needed for the momentary irregular swinging motion when starting and stopping the device. Eventual beams under the body have to be installed in such a way that the material that gathers on top of them does not touch the body. Correspondingly, the fixing points of the springs have to be such that there is no possibility for sufficient material to gather near to them as to cover the springs and damage them. If the body hits the funnel, or another fixed structure, when the vibrating device is running, loading increases to a multiple of the designed loading, leading to a device failure. The discharge opening of the funnel that feeds material onto the vibrating feeder may not be essentially smaller than the body width. This way the whole transversal area of the body can be utilized. Nevertheless, movement gaps of the previously mentioned size have to be left between the body side plate and the side of the funnel. The sides may not extend too far down into the body in order for fed material not to get squeezed between the lower edge of the funnel and the bottom of the vibrating device. The sides have to reach, however, to at least 70 mm below the top edge of the vibrating device body. Chains or a hatch may be used to conduct the material flow discharging from the feeding funnel onto the vibrating device. The hatch may not extend too near to the bottom of the vibrating device. Especially in connection with vibrating devices with a closed bottom, the feeding funnel discharge opening has to be designed and placed in such a way that material cannot have a free flow over the discharge end when the vibrating device is not running. When designing feeding funnels, it has to be observed that the pressure caused by material
4-2
does not exceed the maximum allowable value of the vibrating device (see specifications, chapter ASupport loads and AMinimum measure of springs, loaded). The design of the feeding funnel has to be such that it carries part of the feed mass. When installing funnels, channels or other structures near to the feeder body, the gaps between the structures have to be guarded according to safety regulations of the country of operation (e.g. EN 294).
4.2 Service level There has to be a service level around the vibrating device in order to make maintenance and operation easy. If the service level has not been ordered and delivered together with the device, it has to be built by the user. The service platform of crushing equipment has to comply with the safety regulations valid in the country of operation. All instructions on crushing equipment service levels in force in the country of operation of the vibrating device must observed.
4.3 Transport During transport, the vibrating device must be firmly fixed onto the trailer. Most vibrating chute types have transport supports designed for this purpose. Turn the device into the most appropriate position according to the way of transport (e.g. vibrators upwards and the body downwards).
4.4 Welding The body and other parts of the vibrating device may not be welded without the consent of the manufacturer.

4.5 Electrification It has to be noted that the separate vibrators of electrically driven vibrating devices have to be connected to turn in opposite directions. Safety regulations of the country of operation of the vibrating device have to be observed in electrification. When the operation frequency of the device changes, the vibrators’ regulating values have to be set to correspond to the new frequency. Especially when connecting a spare part vibrator, the regulating values have to be checked. The regulating values can be found in the specification annex.
4.6 Connecting a hydraulic drive It has to be observed that the separate vibrators in hydraulically operated vibrating feeders must be connected to turn in opposite directions.

5.4 Operation
NOTE! Remove eventual transport supports and inspect the device as indicated in point 7.1.
Do not drop big stones into an empty vibrating device, the bottom might get damaged. Try to keep material on the bottom of the device in order to soften the blows of falling big stones. Stones may not be dropped onto the grizzly of the vibrating device. Stones stuck into grizzly openings must be removed in order not to damage the grizzly.
Make sure that the electric connections are properly done and that the cables etc. are in condition of operation. Operate the device only when all necessary safety devices are installed (e.g. covers, emergency stop devices, etc.) and they are in condition of operation.
Material should be fed correctly onto the vibrating device, this conserves the device and gives it a longer service life.
Make sure before starting the device that startup puts nobody in danger. Walk around the device and make sure that nobody is on top of, beside or under it. Warn those in the vicinity before starting.
Check at least once during a shift, as indicated in point 7.1, that the device works properly and for possible failures. Report changes (also in the operation of the device) immediately to the person responsible at the job-site. The device has to be stopped and safety measures have to be taken, if needed.
5.2 Starting When starting the process, the devices removing material from the vibrating feeder have to be started before starting the vibrating device, and the feeding devices after the vibrating device.
Do not climb onto the device when it is running. Also, do not touch moving parts on the device when it is running. When the device is running, do not approach it so much that feed material may pose a risk.
Make sure that in a vibrating device with two vibrators, both vibrators start. Using the vibrating device only with one vibrator (e.g. in a failure situation) leads quickly body damage.
5.3 Stopping The vibrating device and the peripheral devices are stopped in the opposite sequence in respect to starting.

Operation
5.5 Measuring the stroke and the stroke angle There are stickers on the device, where the stroke and stroke angle can be read on during operation. There are black circles of a diameter of 1...20 mm on the sticker. The difference between the diameters is one millimeter. When the body vibrates, the eye perceives two circle rows underneath each other. The stroke is indicated by the circles below each other that are tangent to each other. The diameter of the circle concerned is the stroke. In order to help the determination of the diameter, there is a circular ring in the circles of 5, 10, 15 and 20 mm.
In order to determine the stroke angle, there is a dot in the sticker and lines at 15° intervals. The line, the direction of which the dot seems to move, determines the stroke angle. If the dot moves between the lines, the stroke angle can be estimated according to the nearest lines. In the example of figure 5.5.2 the stroke is 13 mm and the stroke angle is 55°.

Checking the oil level and changing the oil The oil level is checked by opening the cap shown in figure 946894 (7) while the machinery is in the angle of 45 degrees. Some oil should drip from the cap. The oil level indication is reliable when the machinery has been stopped for at least 30 minutes. The oil is changed for the first time at 200 running hours. In the future, oil must be changed every 1,000 running hours and at least twice a year. For oil change, drain the machinery of oil by opening the cap (2) in figure 946894 while the machinery is in operational position. Oil is filled through either of the two caps (3). The recommended oil volume is 4 litres (allowable range is 3.5 to 4.5 litres, this corresponds to oil level of the cap (1) with the angle of 42.5º to 47.5º). Absolute cleanliness is imperative when changing the oil. Recommended oil qualities: For summer use (temperature above -10 ºC): Manufacturer BP ESSO FINA MOBIL NESTE SHELL TEBOIL TEXACO

Grizzlies Grizzly 1 Two adjustable bar grizzly cassettes. Part no. 912977-A Grizzly opening [ mm ] 47 - 96 Weight [ kg ] 894
Follow these instructions when adjusting the grizzly. 1.Clean the grizzly so that the bars can move sideways, and no sand goes between the wedge surfaces. 2.Loosen the screw at the end of the bar. Do not loosen too much, because the counterpart may fall into the funnel or it can come off its loop. If the screw is damaged, it can be changed into a new one. There is a normal nut in the counterpart.
grizzly openings at regular intervals are 47, 54, 62, 71, 82 and 96 mm. The bar should always be added to or removed from the border; this way the packing rubbers overlap the right way. 4.Adjust the outermost openings to the desired size and the bars in the right direction. 5.The bars in the middle are adjusted into regular intervals, or if a larger opening is required, every second opening is left bigger. 6.Tighten the screws (M20), beginning from the outermost, with a torque of 382 Nm (281 ft lbs). Tightening is repeated several times, because when a bar is tightened, it always loosens the adjacent bars. 7.The screws are retightened after 50 service hours and after that when need be, if you notice that the grizzlies have moved.
3.Choose the new grizzly opening area and add or remove a bar or bars (observe the overlapping packing rubbers at the end). The

4.1 OPERATING
4.1.2 Before starting
4.1.1 General
•
Check that the conveyor is free from foreign objects.
•
Make sure that the conveyor belt, the drive and tensioning pulleys, and the idler assemblies are free to rotate. Wet belts can freeze to the pulley so firmly that the rubber will tear loose from the fabric when the conveyor is started. A thin coating of ice on an inclined belt surface can cause a load to slide.
•
Make sure that the mechanical parts and guards of the conveyor are in place, and the inspection and service doors closed.
IMPORTANT! Only persons with a proper training on the operation of the conveyor are allowed to operate the conveyor during a test run and normal work. The operator must be well acquainted with the following: – Structure of the conveyor –
Operating functions
–
Points of danger
•
–
Safe working and moving near the conveyor
Check that all personnel are clear of the conveyor and the discharge area.
•
Give a starting alarm.
–
Removing a block WARNING! Before starting the conveying process and during the operation, make sure that the restricted area is clear of people.
Normal starting and stopping are done with the operating switch, or with the IC panel. (IC = Intelligent control) Further information about using the IC control system is provided in the separate IC instruction manual. When the conveyor is in operation, working and moving in its immediate surroundings must be done with caution. If the conveyor stops by itself, the reason for this must be determined and corrected before attempting to restart the conveyor. A running conveyor must be constantly monitored. The safety switch (Located in the main panel) should not be used to stop the conveyor in normal operation. This can cause unnecessary wear on the switch or a blockage of overflowing material. When the conveyor is running, any cleaning, maintenance, and block removing operations are strictly forbidden. When the diesel engine is running, operations such as cleaning, maintenance, and removing blockages are strictly forbidden.

4.2 REMOVING A BLOCK
4.2.1 Clearing of a jammed main conveyor
CAUTION! Never try to clear the blockage with an excavator. This will cause severe damage to your Lokotrack. If the conveyor stops, follow these instructions: • Stop the process and the feeding equipment. Shut down the engine. Wait until the process has stopped completely. •
Lock the safety switch/valve into the off or disabled position to make sure that the conveyor cannot be accidentally started while the block is being removed.
•
Make sure that material feed to the conveyor cannot start while the block is being removed. Make sure also that the primary Lokotrack is not feeding your LT. Alert loader/excavator operator that maintenance is in process. When removing the block, use suitable equipment and wear appropriate personal protection.
•
If guards or other structures have to be removed, install them back into place when the block has been cleared. Unlock the safety switch/valve.
•
Start the conveyor according to the starting procedures.
Stop the process immediately.
•
Shut down the engine. Wait until the process has stopped completely.
•
Lock the safety switch/valve into the off or disabled position to make sure that the conveyor cannot be accidentally started while the block is being removed.
•
Clear the jammed main conveyor as well as possible. Do not use the excavator. When most of the material is removed, start the main conveyor by using a manual start on the IC panel. If necessary, the main conveyor can be driven in both directions (This is an optional feature in some models).
NOTE: The opposite direction drive is not used with the vibrating chute. •
•
•
•
Observe the belt running direction. Do not reverse the conveyor more than 0,5 m (1’6”). Do NOT use this method, if the rock is too big to pass under the magnetic separator.
For more information please consult separate IC and LT instruction manuals. WARNING! Do NOT use this method, if the rock is too big to pass under the magnetic separator! Use a hook to remove iron bars and wires. Be very careful not to hurt yourself. Never use the hook when the machine is running.

MAINTENANCE
CHAPTER

5.1 BELT TRACKING A properly trained conveyor belt will travel over the center of the troughing rolls, pulleys and return rolls, resulting in lower maintenance costs and improved operation. Conveyor belts can be trained to track properly, unless they are warped or curved from improper manufacture, use or storage. Before any belt adjustment is done, make sure that the conveyor is in level. To inspect that the conveyor is levelled correctly, refer to the unit level indicator for the unit straightness. When adjusting the belt, the following items can be used to control the belt tracking: –
Drive drum position
–
Return roller position
–
Carrying rollers
–
Tail pulley position
Before adjustment, make sure that the conveyor belt is undamaged. A damaged belt will not track properly.
5.1.1 Squaring the pulleys In short conveyors the belt tracking is heavily affected by the position of the drive drum and tail pulley. Before making tracking adjustments, check that the head and tail pulleys are both square to the conveyor frame.
Figure 5-1 Squaring the tail pulley
Squaring the head pulley - Repeat the above process for the head pulley. When adjusting the drive drum location, remember always to loosen the slide beam locking bolts on both sides of the conveyor. This function allows the parts to move without causing any torsion on the drive motor. Adjust until the belt is properly tensioned and the drive pulley is square to the conveyor frame. Tighten the slide beam locking bolts slightly on both sides of the conveyor to the proper torque (30 Nm).
Squaring the tail pulley - Mark the frame member close to the tail pulley (Point A). Use a large square (1) to mark (Point B) on the opposite frame member so that a line between the two points is at a 90° angle to the imaginary centerline of the frame. Adjust tail pulley bearing blocks so that the distance C (the distance between marks A and B and the ends of the tail pulley shaft) is equal on both sides of the frame (fig. 5.1).
Figure 5-2 Loosen the slide beam locking bolts on both sides of the conveyor.

CHAPTER 5 - MAINTENANCE
5.1.2 Adjusting the idlers Adjust for run off by finding the point of maximum run off (D) and adjusting the idler or idlers (E) "ahead" of it. "Ahead" means those idlers which the belt contacts before the point of run off. Roller position exaggerated for illustration purposes in figure 5.3. 1.
Before adjustment
2.
After Adjustment
a. Return roller adjustment is used to center the belt on the tail pulley. Run the conveyor with the belt empty. Loosen the bolts (indicated with arrows in the figure 5.2) and displace the roller assembly. Tighten bolts and test for run off again.
Figure 5-4 Return idler adjustment
b. Carrying idler adjustment is used when the belt does not center with material. Each end of the carrying idler fits into an elongated hole that provides two mounting locations. See figure 5.5. Determine which direction the idler must turn and turn the idler by moving one end to the alternate location.
Figure 5-3 Eliminating run off
Loosen bolts and pivot roll (E) around its mid point the way you would turn a steering wheel to bring a car back into the center of its lane. Make small adjustments, retighten bolts and test for run off after each adjustment. If point of creep changes, adjust idler ahead of the new creep point. Figure 5-5 Carrying roller adjustment
Do not attempt to adjust idlers with the conveyor running. Lock out and tag controls while making adjustments.

CHAPTER 5 - MAINTENANCE
c. If the belt adjustment method a & b have not corrected the belt tracking completely, adjust the tail pulley slightly to make the final correction.
5.2 BELT TENSION The conveyor belt tension is adjusted by relocating the drive pulley position. When adjusting the drive drum location, remember always to release the slide beam locking bolts from both side of the conveyor. This function allows the parts to move without causing any torsion to the drive motor. A belt is properly tensioned when the sag of the loaded belt between two adjacent return rollers is 0,5 - 3% of the distance between the rollers when an empty belt is operating. Sag can be difficult to measure accurately, because of the small distances involved. The practical rule of thumb is, "The proper tension is the lowest possible tension that will prevent the drive pulley from slipping on the belt."
Figure 5-6 Tail pulley adjustment
If the conveyor has a vertical curve, the conveyor belt should remain touching all carrying rollers with material.

CHAPTER 5 - MAINTENANCE
5.3 BELT SCRAPER ADJUSTMENT The scraping force is done by spring force. Rubber, steel or gas springs are generally used methods. Belt scraper tension and condition must be checked daily. Observe the scraper wear daily and replace the scraping element when nesessary. The tension mechanism can be jammed or frosen in muddy / icy conditions and due to this the scraper operation must be checked in the beginning of every shift or daily.
Figure 5-8 Adjusting the rubber spring type pre-cleaner
Use tensioning screw Z to adjust the scraper with a rubber element tensioner.
Figure 5-7 Steel spring type pre-cleaner
Adjust the spring to set the scraper’s pressing force so that the belt becomes properly cleaned.

5.4 BEARING LUBRICATION The bearing size will affect the needed grease amount. In the following table the amount of grease (in grams) is proportined to shaft diameter (in millimeters). Table 5-1 Shaft diameter / mm 40 55 60 80
Amount of grease / g 4 6 6 9
In practice an appropriate amount of grease to each bearing is about 5-10 grams (0.17....0.35 ounch) in every 40 - 50 hours. Use a multi-purpose grease with an NLGI-class 2 rating and a good resistance to water, cold (-30 C/ 22 F) and hot (continuous operating temperature + 100×C/212×F). The grease must have rust and oxidation (RO) inhibitors and it must contain EP-additives. Don't use grease containing molybdenium. The minimum viscosity of the base oil must be 160 mm2/s ( cSt ) in 40×C / 104×F and minimum viscocity index 80.

6.2 CONVEYOR BELT REPAIR
6.1 CONVEYOR REMOVAL AND MOUNTING
6.2.1 Punched belt When it is sensible to repair a punched belt?
DANGER! Always use conveyor’s lifting lugs and approved lifting equipment with adequate capacity when removing or mounting the conveyor.
As a rule of thumb, when a tear is larger than 15% of the belt’s width, it might be more reasonable to renew it. In case the belt is quite new and the tear is small, there are usually 3 possibilities to repair it –
Mechanical connector Repair like this is recommended only for a temporary solution. To avoid damage to the belt scraper, pick the correct fastener, set it properly and grind the bolt ends.
–
Surface patch Repair like this is recommended only for small areas. The patch material is available from belt distributors.
–
Fabric patch A glue-bonded layered patch of rubber and fabric is the recommended way of repairing the belt. The patch material is available from belt distributors.
DANGER! Never attempt to maintain or service the conveyor until the conveyor has stopped completely.
WARNING! Always use appropriate protective equipment (e.g. protective helmet, goggles) when operating, maintaining or servicing the conveyor.
If the conveyor is removed for a maintenance or a repair, ensure that the replacement structure is identical to the original one. If the conveyor’s supporting structure is damaged, the new repaired structure must always be equivalent to a new one. Use only genuine Metso spare parts. The warranty does not cover if either non-Metso or non-conforming parts are used. Never attempt to operate, maintain or service the conveyor unless you understand all procedures necessary to safely and properly perform the task. If you are unsure at any stage, please do not hesitate to contact the nearest authorized Metso Minerals’ service or dealer.

DANGER!
Find out the most appropriate bonding method; hot vulkanizing, cold vulcanizing or mechanical splicing. If electricity is needed, find out the power requirement.
Always use conveyor’s lifting lugs and approved lifting equipment with adequate capacity when removing or mounting the conveyor.
The power requirement depends on the equipment; e.g. Almex 1400 mm vulcanizing press with 32 A three-phase current operates in 400 V voltage.
Although they may look alike, all belts are not the same. Differences in carcass construction and covers will affect belt life and belt tracking. Use only genuine Metso spare parts.
The power requirement in this case: 400V x 32A x 1,73 = 22,5 kW –
The conveyor belt needs to be replaced when: –
The surface rubber is worn out
–
The edges are ripped, the belt is punctured, or the surface has bulged [indicating delamination].
–
When the belt can not be made to track properly.
WARNING! Hot vulcanizing press can cause burn injury. Follow manufacturer instructions. Use protective gloves and avoid contact with hot surfaces. Keep unauthorized personnel away from work area.
A worn belt might damage other parts of the conveyor. Replace the belt promptly when these conditions are observed. When ordering a new belt, notice the following –
Part number
–
Belt width, number of plies, cover thickness and length. If the belt will be field vulcanized, allow enough extra length to make the splice.
Whether you are using mechanical fasteners, hot vulcanizing or cold vulcanizing, always follow manufacturers instructions precisely.
WARNING! The vulcanizing process may release poisonous vapours with a narcotising effect. The vapours irritates eyes and skin, may cause cancer, have a possible risk of irreversible effects and may cause drowsiness and dizziness.
NOTE: If you are unsure at any stage, please do not hesitate to contact maker of the splice.
When preparing for a belt renewal, proceed as follows. –
