Spark Arrestor

WARNING

Failure to heed the following warnings while servicing the spark arrestor could result in serious injury or death.

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.
Do NOT perform service on the spark arrestor while the system is HOT. Exhaust system temperatures can reach extreme temperatures. Allow components to cool sufficiently before proceeding.
Do not stand behind or in front of the vehicle while purging the exhaust system.
Never go under the vehicle while it is inclined.
Wear eye protection and gloves while servicing.

Use the following procedure to periodically purge accumulated carbon from the exhaust pipe.

Remove the arrestor clean-out plug1 located on the bottom of the muffler.
Place the transmission in PARK.
Start the engine.
Purge accumulated carbon from the system by momentarily revving the engine several times.
If carbon is expelled, cover or plug the exhaust outlet and rap on the pipe around the clean-out plug while revving the engine several more times.
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.
Repeat steps 4 and 5 until no more particles are expelled when the engine is revved.
Stop the engine. Allow the arrestor to cool.
Reinstall the arrestor plug and remove the outlet cover or plug.
