■ MUFFLER
• Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any sign
of exhaust leakage is found, stop using the
machine and have it repaired immediately.
• Note that failing to do so may result in the
engine catching on fire.
■ SPARK ARRESTER
• The muffler is equipped with a spark arrester to
prevent red hot carbon from flying out of the
exhaust outlet. Periodically inspect and clean as
necessary with a wire brush. In the State of
California it is required by law (Section 4442 of
the California Public Resources Code) to equip a
spark arrester when a gas powered tool is used
in any forest covered, brush covered, or grass
covered unimproved land. (MA4)
