TM 9-1425-450-12
WARNING
A lithium battery is used in this equipment, and is potentially hazardous if misused or tampered with. The battery contains pressurized sulfur dioxide gas which is toxic. The following precautions must be strictly observed to prevent possible injury to personnel or damage to equipment: Do not heat, incinerate, crush, puncture, disassemble, or otherwise abuse the battery in any way that may cause it to rupture. Do not short-circuit the battery, test for capacity, or attempt to recharge. Do not use any battery showing signs of damage, such as bulging, swelling, disfigurement, a brown liquid in the plastic wrap, or a swollen plastic wrap. Do not bypass internal fuse or replace with a fuse of a different rating. Do not store battery in unused equipment for more than 30 days. Do not dispose of lithium batteries with ordinary trash/refuse. Turn in batteries to your local Defense Reutilization and Marketing Office. Turn off the equipment immediately if you detect the battery compartment becoming unduly hot, hear battery venting (hissing sound), or smell irritating sulfur dioxide gas. Remove and dispose of the battery only after it is cool to touch. In the event of a fire near a lithium battery, rapid cooling of the battery is important. Flood the equipment with water or use a carbon dioxide extinguisher. Control of the equipment fire and cooling may prevent the battery from venting and potentially exposing lithium metal. In the event that lithium metal becomes involved in fire, the use of a graphite based Class D fire extinguisher is recommended, such as Lith-X or Met-L-X. Do not use a Halon type fire extinguisher on a lithium battery fire. Remove the battery when the voltage drops below 20 volts under load (or equipment does not operate properly) and replace with a new battery. If there is a safety incident, or if you believe a safety hazard exists, notify your local safety officer.

WARNING
Serious injury to personnel could result if crew members are in firing danger zones when missile is fired. Make sure that all personnel are clear of firing danger zones before doing missile loading procedure. Make sure crew is out of firing danger zones before pressing trigger. All crew members stay in their firing positions until missile hits target or explodes. Ear damage can occur when missile is fired. All personnel within 50 meters of launcher must wear ear plugs (V-51R or equal). For complete danger zone information and range safety guidelines, refer to AR 385-62.

WARNING
If forward slope at launch site is greater than 30 degrees (300), injury to personnel and damage to equipment may occur when missile is fired. If sideways slope is greater than 10 degrees (100), adequate tracking may be impossible.
WARNING
Do not fire missile over or in the direction of electrical wires. If command-link wires contact a live high voltage power line, injury to personnel and damage to equipment may occur.
WARNING
When launcher is mounted on a vehicle, position vehicle so front or rear of vehicle is in line with target. If launcher is loaded, keep missile pointed toward target area at all times. Observe firing angle limitations when firing over front or rear of vehicle (para 2-66 and 2-78). If missile fails to launch, hand off malfunctioned missile to either left or right side of vehicle so missile always points downrange.

Battery Assembly
Two nickel cadmium battery assemblies are issued with each TOW launcher. One to be installed in the missile guidance set and one spare. Long-lasting because they can be recharged many times on the TOW battery charger. To recharge battery assemblies, see TM 9-6130-470-12. Easily removed from and installed in the missile guidance set. Has enough energy for at least 50 missile firings or training exercises when fully charged. Can be stored at temperatures ranging from -50°C (-60°F) to +50°C (+122°F) without damage. Even though a battery may eventually lose all or part of its charge through self discharge, it can be returned to service on the TOW battery chargers. Charge retention (the ability of a stored battery to retain its energy once it has been charged) is both time and temperature dependent. To minimize this self discharge it is recommended that batteries be stored at lowest possible temperature. Has acceptable life span of three to five years. Battery Charge Retention Storage Schedule
Schedule 1 2 3
Storage temperature 25 ±2.8°C (77 ±5°F) 37.8 ±2.8°C (100 ±5°F) 51.6 ±2.8°C (125 ±5°F) 65.5 ±2.8°C (150 ±5°F)
Hours per day 24 20 4 24
Storage period days 30 14 3
The TOW battery must be recharged every 30 days or as defined in schedule above to maintain proper charge. The TOW battery will not be adversely affected if stored on the ground or on metal, concrete, or wood shelves. 1-14

PERSONNEL:
PROCEDURE
Two MOS 11H (Soldier A will perform all steps except those which call for Soldier B)
WARNING
Do not perform system checkout procedure with encased missile loaded. Missile can be accidentally fired during system checkout.
CAUTION
Before performing system checkout procedure the TOW 2 launcher must be completely set-up. Failure to do this could result in damage to the system. Do system checkout procedure as quickly as possible. If too much time is taken to do system checkout procedure, battery assembly may not have enough power to fire missiles.
NOTE A self test can be initiated by performing steps 10 thru 15 of the system checkout procedure. If the day sight tracker boresight knobs are moved to obtain a steady green lamp indication on the azimuth/ elevation cross. YOU must also perform the night sight boresight check (steps 22 thru 34). The self test and night sight boresight check must be performed if: Moved over rough terrain 10 degree F temperature change System operated more than 4 hours Location change using extended travel mode Operating site changed (ground mode only).

MALFUNCTIONS
After the missile leaves the launch tube, a DUD or IRREGULAR FLIGHT can occur.
DUD. A dud is when the warhead fails to explode. The warheads of all duds should be noted and reported to EOD personnel for disposal. Refer to para 2-40 for DUD procedures. IRREGULAR FLIGHT. An irregular or uncontrolled flight of a missile may occur because of any of the following conditions: Defective missile Poor operator tracking Defective launcher Refer to para 2-41 for IRREGULAR FLIGHT procedures. b. FAILURE TO LAUNCH. When the missile fails to leave the launch tube after the normal 1.5 second delay after pressing the trigger, either a FAILURE TO LAUNCH HANGFIRE or a FAILURE TO LAUNCH - MISFIRE condition exists. FAILURE TO LAUNCH - HANGFIRE. After the trigger is pressed, usually the distinctive impulse of the squibs firing to activate the missile batteries and gyro and the gyro spin noise can be heard. When the missile fails to launch and these prefire functions ARE heard, the condition is FAILURE TO LAUNCH - HANGFIRE. Refer to para 2-38 for FAILURE TO LAUNCH - HANGFIRE procedures, FAILURE TO LAUNCH - MISFIRE. When the missile fails to launch and these prefire functions are NOT heard, the condition is FAILURE TO LAUNCH MISFIRE. Refer to para 2-39 for FAILURE TO LAUNCH - MISFIRE procedures.

FIRING ANGLE LIMITATIONS OF HMMWV (Sheet 1 of 2)
Injury to the gunner and damage to the equipment can occur if the TOW 2 system is fired at angles greater than 20 degrees or less than -20 degrees for all firing positions except over the cargo/loader’s door. If firing over the cargo/loader’s door, firing angles should not exceed +20 degrees or -13 degrees. Pressure waves and flying debris can cause injury to personnel and equipment damage. There are restrictions to the elevation angle in which a missile may be fired from a HMMWV launcher. The restricted firing angles are those greater than 20 degrees or less than -20 degrees for all firing positions except over the cargo/ loader’s door. If firing over the cargo/loader’s door, firing angles should not exceed +20 degrees or -13 degrees. The HMMWV may be struck by the missile or severely damaged by the back blast if the launcher is pointed in a restricted position while being fired. In addition, personnel may be injured. An elevation and depression limiter assembly is provided with the HMMWV as a safety device. When the elevation and depression stops are in the “up” position and pinned, firing angle limitation will be +20 degrees and -10 degrees.

If the elevation and depression stops are disengaged, the following three examples show how the firing angle is limited by the danger of the missile or back blast striking the HMMWV. A.
If the launcher is pointed directly forward then the gunner must not allow the elevation of the launcher to exceed +20 degrees or -20 degrees.
B.
If the launcher is pointed over the right front tire then the gunner must not allow the elevation of the launcher to exceed +20 degrees or -20 degrees.

AIR PRESSURE
The air is “thinner” at higher altitudes. The missile will require more time to correct for a steer error at high altitude than for the same steer error at a low altitude. Since missile steering is done automatically by the weapon system, the gunner only has to track the target through the day sight tracker. The TOW 2 Weapon System will operate properly up to an altitude of 10,000 feet.
2-91.
HIGH WINDS NOTE • Firing missile into a high cross wind can cause slight tracking problems. • Generally, however, the TOW 2 Weapon system will automatically adjust for the effects of cross winds on the TOW missile.
A.
The launcher should be shielded from high winds if possible to avoid tracking problems.
B.
Try to select targets either up or down wind from the launcher.

SALT WATER
NOTE Salt water in contact with night sight could corrode and damage the lens. Do the following procedure to clean the night sight.
A.
Clean lens carefully with fresh water.
B.
Use a clean cotton pad and dab lightly over lens in order to remove traces of water and dry the lens.
C.
Use clean cloth and wipe out traces of water on other parts.

OVER WATER (CONT) (Sheet 3 of 6)
The missile firing range for the given heights above water is determined by using the following four graphs. To use the graphs, first determine the height above water of the TOW 2 launcher. Put a mark at the height on the left-hand column of the graph. Then determine the height above water of the target. Put a mark at that height on the right-hand column of the graph. Connect the two marks with a straight line. Find where the line crosses the center column. The reading at that point on the center column tells the maximum range the missile can travel without getting too close to the water. NOTE If you are measuring in feet, use the graph in step 5 or step 8. If you are measuring in meters, use the graph in step 6 or step 7.
Use to find range of TOW missile BGM-71A, BGM-71A-2, BGM-71A-2A, BTM-71A, BTM-71A-2, BTM-71A-2A or BTM-71A-2B in feet. For example, line (a) on the graph shows the missile can hit the target across an 8000-foot strip of water when launcher is 12 feet above water and target is 36 feet above water. Line (b) shows that when the launcher is 75 feet above water and the target is 3 feet above water, the missile can hit the target across a 9840-foot strip of water.

SMOKE AND AREA FIRES
A. Smoke can obscure the gunner’s line-of-sight and hide the target when using the day sight tracker. The gunner should use the night sight when visibility is limited.
B. A fire can burn through the command-link wire causing you to lose control of the missile. Avoid firing through fire and over fires if there is the possibility that the wires will contact the fire before missile impact.
