Maintenance (continued)
CAUTION!
Do not remove the D-shaped shim
washer from the gearcase clamp!
The shim washer prevents damage
from overtightening the tube clamp
bolt.
Slide the gearcase out of the tube. 3.
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.
50-hour maintenance
Every 50 hours of operation; more
frequnetly 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 contamination,
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 dam-
aged 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.
