Spark Arrester

WARNING

Do not perform clean out immediately after the engine has been run, as the exhaust system becomes very hot. Serious burns could result from contact with exhaust components.

To reduce fire hazard, make sure that there are no combustible materials in the area when purging the spark arrestor.

Wear eye protection.

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. Place the transmission in PARK, lock the parking brake, and block the wheels to prevent roll back.

Failure to heed these warnings could result in serious personal injury or death.

The exhaust pipe must be periodically purged of accumulated carbon as follows:

  1. Remove the clean out bolt 1 located on the bottom of the muffler.

  2. Place the transmission in Park 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 2 and lightly tap on the pipe around the clean out bolt weld nut with a rubber mallet 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. Place the transmission in PARK, lock the parking brake, and block the wheels to prevent roll back. Repeat Steps 2 and 3. SEE WARNING

  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. Place the transmission in PARK, lock the parking brake, and block the wheels to prevent roll back. Repeat Steps 2 and 3. SEE WARNING

  6. Repeat steps 2 through 5 until no more particles are expelled when the engine is revved.

  7. Stop the engine and allow the arrestor to cool.

  8. Reinstall the clean out bolt and torque to specification.
