Cylinder Cooling Fins

Maintenance Interval

The cylinder cooling fins should be cleaned after every

25 hours of operation, or once a week, whichever

comes first

Air must flow freely around and through the cylinder

cooling fins to prevent engine overheating. Leaves,

grass, diit and debris buildup on the fins will increase

the operating temperature of the engine, which can

reduce engine performance and shorten engine life.

Cooling Fin Cleaning

With the engine at ambient (room) temperature,

loosen the knob and remove the air filter cover.
