Clean Spark Arrester

Cleanout Plug
Instructions for cleaning the combination catalytic converter muffler with an internal
spark arrester.
WARNING: BEFORE TOUCHING ANY PART OF AN EXHAUST SYSTEM, BE
ABSOLUTELY SURE THAT IT HAS HAD SUFFICIENT TIME TO COOL!
Disposal of accumulated particles may be accomplished by following the steps
listed below.
CAUTION: Do not perform this operation in an area with combustible materi-
als.
CAUTION: IN A SAFE AREA take precautions to collect and properly dispose
of residue falling from the spark arrester trap.
1. Remove the cleanout plug (pipe plug) on the bottom half or side of the spark
arrester (muffler). Some particles may begin to drain out at this time. Soot mixed
with condensation or other oily liquids may also empty out.
WARNING: KEEP HEAD AND FACE AWAY FROM POSSIBLE DRAINAGE!
2. Without causing deformation (or any type of damage to the spark arrester)
repeatedly tap on the arrester near the cleanout plug. This may be enough to
begin drainage of the spark trap.
3. Cleaning can be accomplished by the following procedure:
• Industrial vacuum cleaners can do a complete job
• IN A SAFE AREA, start the engine. Idle in a neutral gear, if possible. Then
alternate between low idle and high idle for two to three minutes
• Operate the engine as required by the application for two to three minutes
4. If the engine was started, TURN OFF THE ENGINE AND LET THE ARRESTER
COOL AGAIN.
5. Replace the cleanout plug and tighten securely.
6. Dispose of the accumulated particles.
