to cool before proceeding.
The spark arrester must be serviced every 100 hours to keep it
functioning as designed.
Clean the spark arrester as follows:
1. Loosen the screw by the exhaust port of the muffler and remove the
spark arrester.
2. Use a brush to remove carbon deposits from the spark arrester
screen.
Inspect the screen for breaks or tears and replace it if necessary.
3. Install the spark arrester in the reverse order of removal.
