Method For Checking Window Washer Fluid Level, Adding Fluid - Komatsu PW98MR-10 Operation & Maintenance Manual

MAINTENANCE PROCEDURE
1.
Set the work equipment in the position shown in the figure,
then stop the engine and set the lock lever to LOCK posi-
tion (L).
A: Arm
B: Bucket:
2.
Shift O-ring (1) and measure the amount of play "a".
REMARK
Measurement is easier if you move the bucket to one side
so that all the play can be measured at one place (the right
side in the figure).
Use a clearance gauge for easy and accurate measure-
ment.
3.
Loosen plate mounting bolts (2) (4 pieces) and loosen
plate (3).
The shim is a split type, so the work can be performed
without removing the bolts.
4.
Remove shim (4) corresponding to the amount of play "a".
Shim (4) is a set of 2 pieces. The thickness of each piece
of shim (4) is 0.5 mm.
When play "a" is smaller than 1 shim, do not adjust it by
tightening bolts (2).
5.
Tighten bolts (2) (4 pieces).
If bolts (2) are too stiff to tighten, pull out pin stopper bolt
(5) for easier tightening.
