Cooling system maintenance
IMPORTANT
To maintain proper engine operating temperature, cooling air must pass freely through the
cylinder fin area.
This flow of air carries 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. Air intake. 2. Cylinder fins.
 Remove dust and dirt from between fins.
 Before each use, remove accumulated debris from bottom engine intake grille located
between the fuel tank and starter.
