IMPORTANT
• Note that using any spark plug other than those des-
ignated may result in the engine failing to operate prop-
erly or in the engine becoming overheated and dam-
aged.
• To install the spark plug, first turn the plug until it is
finger tight, then tighten it a quarter turn more with a
socket wrench.
MUFFLER
WARNING
• Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust leak-
age is found, stop using the machine and have it re-
paired 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 pre-
vent red hot carbon from flying out of the exhaust out-
let. Periodically inspect and clean as necessary with
a wire brush.

GEAR CASE
• 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 depend-
ing on the job condition.
• Remove the bolt opposit to the grease nipple before
installing new grease to arrange for old grease to exit.
INTAKE AIR COOLING VENT
WARNING
• 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 muf-
fler to become overheated and that 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 in order to be able to view the upper part
of the cylinder.
IMPORTANT
• 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.
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 cylin-
der 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.
10. Storage
Aged fuel is one of major causes of engine starting fail-
ure. 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.
