Spark Arrestor
WARNING
Failure to heed the following warnings while servicing the spar k
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 combus tible materials from the area. Wear eye
protec tion and leather work gloves. Do not stand behind or in
front of the vehicle while purging. Never run th e engine in an
enclosed area. Exhaust contains poisonous carbon monoxide
gas. Never go under the vehicle while it’ s inclined.
Use the following pr ocedure to periodically pu rge accumulated carbon
from t he exhaust pipe/muffler.
1. Remove the arrestor clean-out
plug (1) from the bottom of the
muffler.
2. Place the transmission in PARK
and start the engine.
3. Purge carbon from the system by
momentarily revving the engine
several times.
4. If carbon is expelled, cover or plug the
exhaust outlet (2) and rap on the pipe around
the cleanout 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. Set the parking brake
and block the wheels. Make sure the vehicle is in PARK and
repeat steps 3 and 4 until no more particles are expelled when the
engine is revved.
6. Stop the engine and allow the arrestor to cool. Reinstall the
arrestor plug and remove the outlet cover or plug.
