SERVICING YOUR LAWN MOWER

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 and disconnect the spark plug cap to
prevent accidental starting.
2. Remove the three flange bolts and the heat shield. Remove the
two set screws and the spark arrester from the muffler.
3. 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.
4. Installation is the reverse of removal. Tighten all hardware
securely.
5. Reconnect the spark plug cap.
