• Aged fuel is one of major causes of
engine starting failure. Before storing
the unit, empty the fuel tank and run
the engine until it uses all the fuel left in
the fuel line and the carburetor. Store
the unit indoor taking necessary
measures for rust prevention.

11. Disposal
• When disposing your machine, fuel or
oil for the machine, be sure to allow
your local regulations.
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 brushcutter.
Note that it is necessary to remove the
engine cover shown in (MA7) in order
to be able to view the upper part of the
cylinder.
• If waste gets stuck and causes
blockage around the intake air cooling
vent or between the cylinder fins, it may
cause the engine to overheat, and that
in turn may cause mechanical failure
on the part of the brushcutter. (MA7)

■ PROCEDURES TO BE PERFORMED
AFTER EVERY 100 HOURS OF USE
1. Remove the muffler, insert a
screwdriver into the vent, and wipe
away any carbon buildup. Wipe away
any carbon buildup on the muffler
exhaust vent and cylinder exhaust port
at the same time.
2. Tighten all screws, bolts, and fittings.
3. Check to see if any oil or grease has
worked its way in between the clutch
lining and drum, and if it has wipe it
away using oil-free, lead-free gasoline.
IMPORTANT
■ 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. (MA5)

■ GEAR CASE (MA6)
• The reduction gears are lubricated by
multipurpose, lithium-based grease in
the gear case. Supply new grease
every 25 hours of use or more often
depending on the job condition.
• Remove the side bolt in gear case
opposite of grease nipple before
installing new grease to arrange for old
grease to exit.
■ 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
