Safety Rules

OPERATION

MAINTENANCE & STORAGE

Keep hands and feet away from rotating parts. Keep clear of discharge opening at all times.

Always clear snow up and down the face of slopes, never across the face. Use extreme caution when changing direction on slopes. Do not attempt to clear slopes over 17.7% (10o).

Use extreme caution when operating on or crossing gravel drives, walks or roads. Stay alert for hidden hazards and traffic.

Be especially careful not to touch snowthrower parts which might be hot from operation. Allow such parts to cool before attempting to maintain, adjust or ser- vice.

If unit starts to vibrate abnormally, disengage drives and stop the engine. Check immediately for the cause. Vibration is generally a warning of trouble.

Before leaving operator’s position for any reason:

-shut off engine,

-remove the Engine Key and

-wait for all moving parts to stop.

Before cleaning, repairing or inspecting the unit, make certain all moving parts have stopped. Remove the key and then disconnect the spark plug wire to prevent accidental starting.

Always use a grounded, 3-wire plug receptacle for electric starting.

Adjust snow discharge angle for safe flow when oper- ating near glass enclosures, automobiles, window wells, dropoffs, etc.

Do not overload machine capacity by clearing snow at too fast a ground speed.

Never operate machine at high transport speeds on slippery surfaces. Use care when backing up.

Disengage Auger Control when transporting or not in use.

Never operate the snowthrower without good visibility or light. Always be sure of your footing.

Do not change the engine governor settings or over- speed the engine.

Never direct the discharge chute at bystanders; nor allow anyone in front of the unit while it is operational.

Never operate this machine without all of the proper guards or other safety protective devices in place.

Keep all nuts, bolts and screws tight to ensure that the equipment is in safe operating condition.

Never store equipment with gasoline in the tank in a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.

Always refer to the Operator’s Manual for important details if snowthrower is to be stored for an extended period.

Run auger drive a few seconds after completion of throwing snow to help clear out snow and prevent icing and freeze-up on unit.
