Servicing Spark Arrestor Muffler
Every 200 hours operation, clear the muffler of carbon
buildup.
1. Remove pipe plug from clean–out port at lower side
of muffler.
CAUTION
Be careful while working around muffler as it
may be hot and could cause injury.
2. Start engine. Plug the normal muffler exit with block
of wood or metal plate so exhaust flow will be forced out
of the clean–out port. Continue to block exit until carbon
deposits cease coming out port.
CAUTION
Do not stand in line with the clean–out
port. Always wear safety glasses.
3. Stop engine and replace pipe plug.
