MAINTENANCE

Exhaust Pipe

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
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 hand brake and block the
wheels. Make sure the machine is in neutral and repeat
Steps 2 and 3. See WARNING in this section.
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 hand brake and block the
wheels. Make sure the machine is in neutral and repeat

combustible materials in the area when purging the
spark arrestor.

* Do not stand behind or in front of the vehicle while
purging the carbon from the spark arrestor.Never
run the engine in an enclosed area.
* Exhaust contains poisonous carbon monoxide
gas.
* Do not go under the machine while it is inclined.
Set the hand brake and block the wheels to prevent
roll back.
Failure to heed these warnings could result in
serious personal injury or death.
