■ 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. (MA6)
• When removing and installing the holder(A), use
care not to allow any dirt and dust entering in to the
gear case. (MA6)
