Lubricate the cutter assembly gearbox
by pumping one or two strokes of
lithium-base grease into the grease fit-

CAUTION!
Overlubricating can cause the gearbox
to operate sluggishly and can cause
grease to leak out.

50-hour Maintenance
Every 50 hours of operation
(more frequently in dusty or
dirty conditions):
Remove and clean the cylinder cover
and clean dirt and debris from the cylin-
der cooling fins.
Lubricate the gearcase.
To perform
this operation, first remove the gearcase
from the outer tube as follows:
CAUTION!
Do not remove the D-shaped shim
washer from the gearcase clamp! The
shim washer prevents damage from
overtightening the tube clamp screw.
a. Loosen the gearcase clamp bolt.
b. Remove the index bolt from the
gearcase.
c. Slide the gearcase out of the tube.
Using a grease gun, pump lithiumbase
grease (about 10 grams) into the
grease fitting on the gearcase until you
see old grease being purged from the
gearcase. Purged grease will be visible
in the outer tube cavity. Clean up excess
grease, then reassemble the gearcase
onto the outer tube. Make sure the
index bolt fits into the hole on the outer
tube. Securely tighten both bolts.

CAUTION!
Make sure you do not pierce the fuel
line with the end of the hooked wire.
The line is delicate and can be dam-
aged easily.
Use a hooked wire to extract the fuel
filter from inside the fuel tank. Inspect
the fuel filter element for signs of
contamination. Replace it with a new
one if required. Before reinstalling
the filter, inspect the fuel line. If you
find damage or deterioration, remove
the unit from service until it can be
inspected by a Shindaiwa-trained
service technician.
