•  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 after
removing the air cleaner and the cylinder cover.

When installing the cylinder cover, make sure that switch wires
and grommets are positioned correctly in place.
