SPARK ARRESTER MAINTENANCE
It is recommended to inspect and clean the spark arrester every
200 hours of operation.
1. The spark arrester is located outside the muffler, which gets very
hot during operation. Allow the engine to cool completely before
servicing the spark arrester.
2. Remove the two screws holding the cover plate that retains the
end of the spark arrester to the muffler.
3. Remove the spark arrester screen.
4. Carefully clean and remove the carbon deposits from the spark
arrester screen with a wire brush. Replace the spark arrester if it is
damaged.
5. Reinstall the spark arrester in the muffler and secure it in place
with the screws.
