CLEANING

Level 2.

Tools required:

Cross-head screwdriver, 3 and 4 mm hex wrench,
25 - 50mm (1 - 2 in.) cleaning brush.

Parts Required: None if you are careful.

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 or cleaning of cooling fins is
considered “Normal Maintenance.” Any failure attributed to lack of
maintenance is not warranted.
