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 engine. 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 suspected to be in the muffler, back the
machine onto an incline so the rear of the machine is one foot
higher than the front. Set the parking brake and block the wheels.
Make sure the machine is in neutral and repeat steps 2 and 3.
WARNING: SEE BELOW.
5. If particles are still suspected to be in the muffler, drive the

WARNING: SEE BELOW.
6. Repeat steps 2 through 5 until no more particles are expelled when
