SPARK ARRESTER
• The muffler is equipped with a spark arrester to prevent red
hot carbon from flying out of the exhaust outlet. Periodically
inspect and clean as necessary with a wire brush in the re-
pair specialty store.

INTAKE AIR COOLING VENT
WARNING
• Check the intake air cooling vent after every 25 hours of
use for blockage, and remove any waste which has at-
tached itself to the machine.
IMPORTANT
• If waste gets stuck and causes blockage around the intake
air cooling vent, it may cause the engine to overheat, and
that in turn may cause mechanical failure on the part of the
machine.

GUIDE BAR
Remove sawdust in the guide bar groove and the oiling port.
(Type: Sprocket nose)
Grease the nose sprocket from the feeding port on the tip of the
bar.
The guide bar rail should always be a square. Check for wear
of the guide bar rail. Apply a ruler to the bar and the outside of
a cutter. If a gap is observed between them, the guide bar rail
is normal. Otherwise, the guide bar rail is worn. Such a bar
needs to be corrected or replaced.
