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.
