Spark Arrester Service (Optional Part) - Honda HP400 Owner's Manual

Spark Arrester Service (Optional part)
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 Honda 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 two 6 mm nuts and remove the muffler protector, identification
plate, muffler and gasket.
2. Remove the spark arrester from the muffler.
