Cylinder Cooling Fins; Spark Arrester - Maruyama E23 Manuel Du Propriétaire/De L'utilisateur

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, dirt 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
1. With the engine at ambient (room) temperature,
loosen the knob and remove the air filter cover.
