Maintenance
Wait until the muffler is cool before
performing any maintenance.
SPARK ARRESTOR SCREEN should be inspected every
100 hours of engine usage.
1. Loosen the two nuts on the clamp and slide clamp off,over
the tailpipe extension.
2. Remove tailpipe extension. The extension may have be-
come tight to the muffler as a result of the crimping action
of the clamp. Pliers may be required for extra grip when
twisting the extension off.
3. Slide the Spark Arrestor Screen out of the muffler and
shake the screen to remove the built up soot and carbon.
The amount of carbon collected will vary with fuel used, air
quality,engine age and condition. (A soft metel brush may
be required to fully clean the screen.)
4. Cartefully inspect the screen for any tears, rips, or any
other damage which will prevent the screen from operating
properly. Replace screen if damaged.
5. Re-install the cleaned and inspected screen.

taining ring is against the tip of the tailpipe.

be “snug” fit.
3. Slide the clamp over the extension until it circles the ex-
panded section of the extension where the tailpipe and ex-
tension overlap. Tighten the two clamp bolts evenly.
