EXHAUST PIPE
The exhaust pipe must be periodically purged of accumu-
lated carbon as follows:
1. Remove the clean out plugs located on the bottom of the
muffler as shown at right.
2. Place the transmission in neutral and start the engine.
Purge accumulated carbon from the system by momen-
tarily 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 neu-
tral and repeat steps 2 and 3. WARNING: SEE
BELOW.
5. If particles are still suspected 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 parking brake
and block the wheels. Make sure the machine is in neu-
tral and repeat steps 2 and 3. WARNING: SEE
BELOW.
6. Repeat steps 2 through 5 until no more particles are ex-
pelled when the engine is revved.
7. Stop the engine and allow the arrestor to cool.
8. Reinstall the clean out plugs.

no combustible materials in the area when purging the spark
arrestor.
