COOLING SYSTEMS CLEANING
Level 3.
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 engine cover
(A) from the engine and lay to the front of the edger.
