MAINTENANCE
Spark Arrestor
The exhaust pipe must be periodically purged of accumulated carbon as follows:
1. Remove the clean out
plugs located on the bottom
of the muffler as shown
above.
2. Place the transmission in
neutral and start the en-
gine. Purge accumulated
carbon from the system by
momentarily revving the
engine several times.
3. If some carbon is expelled,
cover the exhaust outlet
and rap on the pipe around
the clean out plugs while
revving the engine several
more times.
4. If particles are still sus-
pected to be in the muffler,
back the machine onto an
incline so the rear of the ma-
chine is one foot higher
than the front. Set the park-
ing brake and block the
wheels. Make sure the ma-
chine is in neutral and re-
peat steps 2 and 3. WARN-
ING: SEE BELOW.
5. If particles are still sus-
pected to be in the muffler,
drive the machine onto the
incline so the front of the
machine is one foot higher
than the rear. Set the park-
ing brake and block the
wheels. Make sure the ma-
chine is in neutral and re-
peat steps 2 and 3. WARN-
ING: SEE BELOW.
6. Repeat steps 2 through 5
until no more particles are
expelled when the engine is
revved.
7. Stop the engine and allow
the arrestor to cool.
