Level 2.

Tools required: 4 mm Hex wrench, 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 or cleaning of cooling fins is

considered “Normal Maintenance.” Any failure attributed to lack of

maintenance is not warranted.
