Cooling system maintenance
Tools required: Cleaning brush
Parts required: None, if you are careful.
Cleaning Grill
1.
Brush accumulated debris from crankcase intake grill above
the fuel tank.
Exhaust system
Carbon deposits in silencer will cause a drop in engine output
and overheating. Spark arrestor screen must be checked pe-
riodically. Clean deposits from silencer.
IMPORTANT
To maintain proper engine operating temperature, cooling air must pass freely through the cylinder fin area. This flow of air car-
ries combustion heat away from the engine.
Overheating and engine seizure can occur when:
Air intakes are blocked, preventing cooling air from reaching the cylinder,
or
Dust and grass build up on the out side of the cylinder. This build-up insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages or cleaning of cylinder fins is considered "Normal Maintenance". Any resultant failure
attributed to lack of maintenance is not warranted.
1. Silencer
IMPORTANT
Do not remove the silencer cover. If necessary, Please consult
your dealer.
