cooling system

Level 2.

Tools required: 25-50 mm (1-2 in.) cleaning brush, 4 mm Hex

Wrench

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.

Cleaning Grill

1.Brush accumulated debris from crankcase intake grill above the

fuel tank.

Cleaning Cylinder Fins

1. Remove engine cover (two screws), pull cover away from engine. Clean cylinder fins to allow cooling air to pass freely.

2. Loosely reassemble engine cover with two screws.

3. Tighten all screws securely.
