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 muffler heat 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. Installation is the reverse of removal. Tighten all hardware 

securely.

6. Install the spark plug cap on the spark plug.
