Complete a walk-around inspection of the unit to understand the unit, your work area and all safety decals. 3. DANGER! Understand how to operate all controls, the functions of all controls and how to STOP in an emergency. Danger! ROTATING PARTS! Keep clear of auger while engine is running. • Read operator’s manual. • Allow operation only by properly-trained adult, never children. • Stop engine and remove ignition key prior to leaving the operator’s position for any reason.
Never attempt to make any adjustments while the engine is running (except when specifically recommended by manufacturer). Always allow unit and engine to adjust to outdoor temperature before clearing snow. 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. Operation Never operate the snow thrower without proper guards, and other safety protective devices in place and working.
Avoid contact with sharp edges; sharp edges can cut. Always refer to operator's manual for important details if the snow thrower is to be stored for an extended period. Do not throw snow higher than necessary. Maintain or replace safety and instruction labels as necessary. Clearing a Clogged Discharge Chute Hand contact with the rotating auger / impeller inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute.
Fuel DO NOT run engine in an enclosed area. Always provide good ventilation. Fumes from engine exhaust can cause injury or death. Fuel is highly flammable and its vapors are explosive. Handle with care. Use only an approved gasoline container with an appropriately-sized dispensing spout. No smoking, no sparks, no flames. Always allow engine to cool before servicing. Never fill fuel tank when engine is running or hot from operation. Never fill or drain fuel tank indoors.
