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.

1.Remove spark plug lead and throttle linkage end from the carbure- tor swivel.

2.Remove the four screws that retain the cover. Two at the top of the Recoil Starter, two on either side of the front. Lift the cover from the engine and lay to the front of the trimmer.

NOTE

The throttle linkage remains assembled to the cover and the spark plug lead and grommet remain installed.
