■ MUFFLER
• Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any
sign of exhaust leakage is found, do not use
the brushcutter 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. (MA8)
■ GEAR CASE
• The reduction gears are lubricated by
multipurpose, lithium-based grease in the gear
case. Supply new grease every 50 hours of use
or more often depending on the job condition.
• Remove the cutter holders before installing new
grease to arrange for old grease to exit. (MA9)
■ 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 brushcutter 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. Note that
failing to do so could cause the muffler to
