MAINTENANCE
Spark Arrestor
Use the following procedure to periodically purge accumulated carbon
from the exhaust pipe.
1. Remove the arrestor clean-out
plugs located on the bottom of
the muffler.
2. Shift the transmission to neutral.
Apply the brakes. Start the
engine.
3. Purge accumulated carbon from
the system by momentarily rev-
ving the engine several times.
4. If carbon is expelled, cover or
plug the exhaust outlet and rap
on the pipe around the clean-out
plugs 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. Engage the park brake.
Block the wheels. Make sure the transmission is in neutral and
repeat steps 3 and 4 until no more particles are expelled when the
engine is revved.
6. Stop the engine. Allow the arrestor to cool.
7. Reinstall the arrestor plugs and remove the outlet cover or plug.
WARNING
Failure to heed the following warnings while servicing the spark arrestor
could result in serious injury or death.
Do not perform service on the spark arrestor 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 contains poisonous
carbon monoxide gas that can cause loss of consciousness or death in a
very short time.
Never go under the vehicle while it's inclined.
