MAINTENANCE
Spark Arrester
Failure to heed the following warnings while servicing the spark
arrester could result in serious injury or death.
Do not perform service on the spark arrester while the system is hot.
Exhaust system temperatures can reach 1000° F. Allow components
to cool sufficiently before proceeding.
Remove any combustible materials from the area.
Wear eye protection and gloves.
Do not stand behind or in front of the vehicle while purging.
Never run the engine in an enclosed area. Exhaust can cause loss of
consciousness or death in a very short time.
Never go under the vehicle while it's inclined.
Use the following procedure to periodically purge accumu-
lated carbon from the exhaust pipe.
1. Remove the arrester
clean-out plug located
on the bottom of the
muffler.
2. Place the transmission in
Park. Start the engine.
3. Press the brake pedal and then press the travel control
pedal to increase engine RPM. Purge accumulated carbon
from the system by momentarily revving the engine sev-
eral times.
4. If carbon is expelled, partially cover the exhaust outlet and
rap on the pipe around the clean-out plug while revving
the engine several more times.
5. If particles are still suspected to be in the muffler, elevate
the rear of the vehicle one foot higher than the front. Block
the wheels.
6. Repeat steps 3 and 4 until no more particles are expelled
when the engine is revved.
7. Stop the engine. Allow the arrester to cool.
8. Reinstall the arrester plug and remove the partial outlet
cover.
