6. 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
remove sawdust. If you do not, it will cause the overheating.
Keep clean area around the muffler.
This engine is air-cooled. Dirt 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 re-
moving the air cleaner and the cylinder cover.
When installing the cylinder cover, make sure that switch wires
and grommets are positioned correctly in place.
