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 repair 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 attached 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.

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.
