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 from spark plug and throttle linkage end
from the carburetor swivel.
2.
Remove the four screws that retain the engine cover (A). 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 Power Pruner
