SAFETY WARNING: AVOID INJURY. This snow thrower is capable of crushing or amputating body parts. Failure to observe the safety instructions in the manuals and on decals could result in serious injury or death. ALWAYS disengage auger, stop unit and engine, remove key and allow moving parts to stop before leaving operator’s position. Read these safety rules and follow them closely.
4. Notice Safety Decal Descriptions NOTICE: Indicates information or procedures that are considered important but not hazard related. If not followed, property damage could result. 1. CAUTION! Danger! 5. Important IMPORTANT: Indicates general reference information worthy of special attention. SAFETY DECALS The safety decals on your machine are visual reminders of the important safety information in this manual. All messages on your unit must be fully understood and carefully followed.
Complete a walk-around inspection of the unit to understand the unit, your work area and all safety decals. 2. 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.
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 Disengage all controls before starting engine. Never operate the snow thrower without proper guards, and other safety protective devices in place and working. Never leave a running unit unattended.
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. Clearing a Clogged Discharge Chute Maintain or replace safety and instruction labels as necessary. 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.
