coolIng system
Level 2.
Tools required:
Cleaning brush 25 - 50 mm (1 - 2 in.)
Parts Required: None.
IMPORTANT
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 is considered "Normal Mainte-
nance." Any failure attributed to lack of maintenance is not warranted.
1. Use brush to remove dirt from engine.
