Maintenance
■
GEAR CASE
• The reduction gears are lubricated by
multipurpose, lithium-based grease in the
gear case. At every 20 hours of use, supply
the gear case with new grease.
• When removing and installing the cutter
holder(a), use care not to allow any dirt and
dust entering in to the gear case.
■
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 stick edger 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 stick
edger. Note that failing to do so could
cause the muffler to become
overheated, and that this in turn could
cause the stick edger 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
WARNING
NOTE
every 25 hours of use for blockage, and
remove any waste which has attached itself
to the stick edger. Note that it is necessary
to remove the plug guard shown in the
picture below 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
stick edger.

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 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.
