ADDITIONAL INFORMATION
SPARK ARRESTER SERVICE (optional equipment)
Your lawn mower 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. An optional USDA
approved spark arrester is available from an authorized Honda
servicing dealer.
The spark arrester must be serviced every 100 hours to keep it
functioning as designed.
1. Allow the engine to cool, then remove the two nuts from the muffler
shield, using a 10 mm socket wrench.
2. Remove the muffler shield, identification plate, muffler, and gasket.
3. Remove the spark arrester from the muffler.
4. Check for carbon deposits on the spark arrester and the exhaust
port. Brush carbon deposits away. Be careful to avoid damaging
the spark arrester screen.
5. Install the spark arrester in the muffler.
6. Install the muffler components on the engine, and tighten the two
nuts securely.
