■ 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.
■ MAINTENANCE BEFORE STORAGE
• Old fuel left in the carburetor may cause
starting failure. When a series of operation
finished, make sure to empty the fuel tank
and drain the carburetor.
• Check all parts and the functions. If the
failured or damaged parts have been found,
replace them with new ones.
■ 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 depending 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
• 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 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.
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.

■ IMUFFLER

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.
