Operation 1. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times. 2. Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. 3. After striking a foreign object, stop the engine (motor), remove the wire from the spark plug, disconnect the cord on electric motors, thoroughly inspect the snow thrower for any damage, and repair the damage before restarting and operating the snow thrower. 4. If the unil should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibration is generally a warning of trouble. 5. Stop the engine (motor) whenever you leave the operating position, before uncloggingthe collector/impeller hous~ngor discharge chute, and when making any repairs, adjustments or inspections.
6. When cleaning, repairingor inspectingthe snow thrower, stop the engine and make certain the collector/impeller and all moving parts have stopped. Disconnect the spark plug wire and keep the wireaway from the plug to prevent someone from accidentally starting the engine. 7. Do not run the engine indoors, except when starting the engine and for transporting the snow thrower in or out of the building. Open the outside doors; exhaust fumes are dangerous. 8. Exercise extreme caution when operating on slopes. 9. Never operate the snow thrower without proper guards, and other safety protective devices in place and working. 10. Never direct the discharge toward people or areas where property damage can occur. Keep children and others away. 11. Do not overload the machine capacity by attempting to clear snow at too fast a rate. 12. Never operate the machine at high transport speeds on slippery surfaces. Look behind and use care when operating in reverse. 13. Disengage power to the collector/impeller when snow thrower is transported or not in use. 14.
