Maintenance and care
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.
