Way of the cooling air

• The engine metal parts can burn your skin. Never touch the

cylinder, muffler or ignition plug etc. during operation or right
after stopping the engine.

• Before starting the engine, check around the muffler and

take off sawdust. If you do not, it will cause the overheating
and a fire. For preventing the trouble, please keep clean
around the muffler.

This engine is air-cooled. Dust clogging between the inlet port
of the cooling air and cylinder fins will cause overheating of the
engine. Periodically check and clean the cylinder fins in the
repair specialty store.

that engine has stopped and is cool. Disconnect the spark
plug to prevent accidental starting.
