6.When cleaning, repairing or inspecting the snow thrower, stop the engine and make certain the collector/impel- ler and all moving parts have stopped. Disconnect the spark plug wire and keep the wire away 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 work- ing.

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.Use only attachments and accessories approved by the manufacturer of the snow thrower (such as wheel weights, counterweights, or cabs).

15.Never operate the snow thrower without good visibility or light. Always be sure of your footing, and keep a firm hold on the handles. Walk; never run.

16.Never touch a hot engine or muffler.

Clearing a Clogged Discharge Chute

Hand contact with the rotating impeller inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the dis- charge chute. To clear the chute:

1.SHUT THE ENGINE OFF!

2.Wait 10 seconds to be sure the impeller blades have stopped rotating.

3.Always use a clean-out tool, not your hands.

Maintenance and Storage

1.Check shear bolts and other bolts at frequent intervals for proper tightness to be sure the equipment is in safe working condition.

2.Never store the machine with fuel in the fuel tank inside a building where ignition sources are present such as hot water heaters, space heaters, or clothes dryers. Allow the engine to cool before storing in any enclosure.

3.Always refer to operator’s manual for important details if the snow thrower is to be stored for an extended period.

4.Maintain or replace safety and instruction labels, as necessary.

5.Run the machine a few minutes after throwing snow to prevent freeze-up of the collector/impeller.
