10. Maintenance
5. Spark arrester
The muffler is equipped with a spark arrester to
prevent red hot carbon from flying out of the exhaust
outlet. Periodically check and clean as necessary with
a wire brush after removing two muffler cover nuts and
one screw.

NOTE
Never use a muffler if the spark arrester is missing or
defective.
6. Exhaust port
Remove the muffler, insert a screwdriver into the vent,
and wipe away any carbon buildup after every 100
hours of use. Wipe away any carbon buildup on the
muffler exhaust vent and the cylinder exhaust port at
the same time.

7. Sprocket
Check for cracks and for excessive wear interfering
with the chain drive. If the wear is considerable,
replace it with new one. Never fit a new chain on a
worn sprocket, or a worn chain on a new sprocket.
