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
