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