SPARK ARRESTER SERVICE (optional equipment)
Your engine is not factory-equipped with a spark arrester. In some areas, it is illegal to operate
an engine without a spark arrester. Check local laws and regulations. A spark arrester is
available from authorized servicing dealers.
The spark arrester must be serviced every 100 hours to keep it functioning as designed.
If the engine has been running, the muffler will be very hot. Allow the muffler to cool before
servicing the spark arrester.
1. Remove the three 4 mm screws from the exhaust deflector, and remove the deflector.
2. Remove the four 5 mm screws from the muffler protector and remove the muffler protector.
3. Remove the 4 mm screw from the spark arrester, and remove the spark arrester from the
muffler.
4. Use a brush to remove carbon deposits from the spark arrester screen. Be careful to avoid
damaging the screen.
The spark arrester must be free of breaks and holes. Replace the spark arrester if it is
damaged.
5. Install the spark arrester, muffler protector, and exhaust deflector in the reverse order of
disassembly.
