Maintenance (continued)
50-hour maintenance
Ever y 50 hours of operation; more
frequnetly in dusty conditions:
■
Remove and clean the cylinder cover
and clean dirt and debris from the cyl-
inder cooling fins.
Remove and replace the fuel filter
element.
■
Use a hooked wire to extract the fuel filter
from inside the fuel tank. Inspect the fuel
filter element. If it shows signs of contam-
ination, replace with a genuine Shindaiwa
replacement fuel filter element.
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.
Before reinstalling the new filter element,
inspect the condition of all the fuel
system components (fuel pick-up line,
fuel return line, tank vent line, tank
vent, fuel cap and fuel tank). If damage,
splitting or deterioration is noted, the
unit should be removed from service
until it can be inspected or repaired by a
Shindaiwa-trained service technician.
Gearcase lubrication
To perform this operation, first remove the
gearcase from the outer tube as follows:
1.
Loosen the gearcase clamp screw.
2.
Remove the index screw from the
gearcase.
CAUTION!
Do not remove the D-shaped shim
washer from the gearcase clamp! The
shim washer prevents damage from
overtightening the tube clamp screw.
3.
Slide the gearcase out of the tube.
Using a grease gun, pump lithium-
base grease (about 10 grams) into the
grease fittings on the gearcase until
you see old grease being purged from
the gearcase. Purged grease will be
visible in the outer tube cavity.
4.
Clean up excess grease, then reassem-
ble the gearcase onto the outer tube.
Make sure the index screw fits into
the hole on the outer tube. Securely
tighten both screws.
