Spark Arrester Inspection
The spark arrester must be serviced every 1,000
miles (1,600 km) of running or 100 operating
hours to maintain its efficiency.
Regular servicing prevents carbon buildup
(which can diminish engine performance) and
also complies with USDA regulations for regular
maintenance to assure proper function.
The spark arrester prevents random sparks from
the combustion process in your engine from
reaching the environment.
1. Allow the engine and muffler to cool.
2. Remove the bolts (1), spark arrester (2), and
gasket (3) from the muffler.
