■ 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)

■ GEAR CASE
• The reduction gears are lubricated by
multipurpose, lithium-based grease in the gear
case. At every 25 hours of use, supply the gear
case with new grease. (MA5)
• Remove the cutter holders before installing new
grease to arrange for old grease to exit. (MA7)
• When removing and installing the holder(A), use
care not to allow any dirt and dust entering in to
the gear case. (MA7)
■ DRIVE SHAFT (MA6)
• The drive shaft is lubricated by multipurpose
lithium-based grease (NLGI No.2). Pull out the
shaft from the pipe and supply new grease every
50 hours of use or more often depending on the
job condition.
