50-Hour Maintenance
AH231_36
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 cylinder cooling fins.
■
Lubricate the gearcase
. To
perform this operation, first remove
the gearcase from the outer tube as
follows (Figure 28.):

Gearcase
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 lithium-
base grease (about 10 grams) into
the grease fitting on the gearcase
until you see old grease being
purged from the gearcase (Figure
29). 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 damaged easily.
■
Use a hooked wire to extract the
fuel filter from inside the fuel tank
(Figure 30). Inspect the fuel filter
element. If it shows signs of
contamination from debris, replace
it with a genuine Shindaiwa replace-
ment fuel filter element. Before
reinstalling the filter, inspect the
fuel line. If you discover damage or
deterioration, the unit should be
removed from service until it can be
inspected by a Shindaiwa-trained
service technician.
CAUTION!
Do not remove the D-shaped shim
washer from the gearcase clamp!
The shim washer prevents
damage from overtightening the
tube clamp screw.
