MAINTENANCE
Note that using any spark plug other than those
designated may result in the engine failing to operate prop-
erly or in the engine becoming overheated and damaged.
To install the spark plug, first turn the plug until it is fin-
ger tight, then tighten it a quarter turn more with a socket
wrench.
MUFFLER
Inspect periodically 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.
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.
MAINTENANCE
PROCEDURE 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 be-
tween the clutch lining and drum, and if it has, wipe it away us-
ing oil-free, lead-free gasoline
ANGLE TRANSMISSION:
The reduction gears are lubricated by multipurpose, lith-
ium-based grease in the angle transmission. Sup-ply new
grease every 25 hours of use or more often depending on
the job condition.
Remove the cutter
holders before installing
new grease to arrange
for old grease to exit.
