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.
ENGLISH
Remove and replace the filter element.
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 (22T
Only)
1. To perform this operation, first remove
the gearcase and debris
shield from the outer tube as follows.
See Figure 4.
CAUTION!
Do not remove the D-shaped shim
washer! The shim washer prevents
damage from overtightening the tube
clamp screw.
Remove the index bolt from the
gearcase.
Loosen the gearcase clamp screw.
Loosen the four socket head cap screws
that secure the cutting attachment
shield.
Slide the gearcase and cutting
attachment shield off the tube. (Do not
lose the two shims).
. Remove the filler plug and press new
grease into the gearcase until old
grease is purged from the gearcase,
which can be seen in the outer tube
cavity.
3. Clean up the excess grease and reinstall
the cutting attachment shield, two
shims and the gearcase.
