Overheating and engine seizure can
occur when:
• Air intakes are blocked,
preventing cooling air from
reaching the cylinder.
• Dust and grass build up on the
outside of the cylinder. This build
up insulates the engine and
prevents the heat from leaving.
Removal of cooling passage
blockages or cleaning of cooling fins is considered “Normal Maintenance.”
Any failure attributed to lack of maintenance is not warranted.
