Level 2.

Tools required: 3 mm Hex wrench, 25 or 50 mm (1 or 2 in.) clean-

ing brush

Parts required: None if you are careful.

IMPORTANT

To maintain proper engine operating temperatures, cooling air must

pass freely through the cylinder n area. This ow of air carries com-

bustion heat away from the engine.

Overheating and engine seizure can occur when:

• Air intakes in the crankcase 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 crankcase cooling passage blockages or cleaning of cooling

ns is considered “Normal Maintenance.” Any failure attributed to lack

of maintenance is not warranted.
