cooling system

Level 2.

Tools required: Air compressor and safety nozzle, or: 4 mm Hex wrench, 25 - 50 mm (1 - 2 in.) cleaning brush.

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

1.Periodically blow dirt and debris off cooling fins with a compres- sor and safety nozzle, or;

2.Remove engine and muffler covers, and brush off dirt and debris using the medium bristle brush.
