Cooling System
Level 2.
To maintain proper engine operating temperatures, 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.
• 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.
Cleaning Grill
1. Brush accumulated debris from
crankcase intake grill above the
fuel tank.
Parts Required: None if you are careful.
