16.DO NOT overload the machine capacity by attempting to clear snow at too fast a rate.

17.Never operate the machine at high transport speeds on slippery surfaces. Look behind and use care when backing.

18.Disengage power to the auger/impeller when snow thrower is transported or not in use.

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

20.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.

MAINTENANCE AND STORAGE

1.DO NOT store machine or fuel container inside where fumes may reach an open flame, spark, or pilot light as in a water heater, furnace, clothes dryer or other gas appliance. Allow engine to cool before storing machine in an enclosure. Store fuel container out of reach of children in a well ventilated, unoccupied building.

2.Keep machine and engine free of excess oil, grease and spilled fuel to reduce fire hazard.

3.When draining fuel tank, drain fuel into an approved container outdoors and away from open flame.

4.Inspect all bolts, nuts and screws frequently and keep properly tightened.

5.Use only recommended shear bolts (if equipped) to prevent possible damage to machine.

6.Service engine and make adjustments only when engine is stopped. Remove key, remove wire from spark plug, secure wire away from plug, and disconnect cord from electric starting motors to prevent accidental starting.

7.DO NOT change engine governor speed settings or overspeed engine.

8.DO NOT test for spark by grounding the spark plug next to spark plug hole. Spark from the plug could ignite gas exiting engine.

9.Have machine serviced by an authorized SNAPPER dealer at least once a year and have the dealer install any new safety devices.
