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)

INTAKE AIR COOLING VENT
• Never touch the cylinder, muffler, or spark
plugs with your bare hands immediately after
stopping the engine. The engine can
become very hot when in operation, and
doing so could result in severe burns.
• When checking the machine to make sure
that it is okay before using it, check the area
around the muffler and remove any wood
chips or leaves which have attached
themselves to the brushcutter. Failing to do
so could cause the muffler to become
overheated, and that this in turn could cause
the engine to catch on fire. Always make
sure that the muffler is clean and free of
wood chips, leaves, and other waste before
use.
• Check the intake air cooling vent and the area
around the cylinder cooling fins after every 25
hours of use for blockage, and remove any
waste which has attached itself to the
