Maintenance (continued)
50-hour maintenance
Ever y 50 hours of operation; more fre-
quently in dusty conditions:Remove and
clean the cylinder cover and clean dirt and
debris from the cylinder 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 bolt.
2. Remove the index bolt 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 bolt.
3. Slide the gearcase out of the tube.
Using a grease gun, pump lithium-
base grease (about 10 grams) into the
grease fitting (B) 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 reas-
semble the gearcase onto the outer
tube. Make sure the index bolt fits into
the hole on the outer tube. Securely
tighten both bolts.
