Windshield Washer - Komatsu 830E Shop Manual

WINDSHIELD WASHER

Operation
The windshield washer, mounted on the right side of
the hydraulic components cabinet behind the cab,
has a 3.8 liter (1 gal) plastic reservoir (1, Figure 3-5)
with a 24 volt electric pump (2).
The washer is controlled by the windshield wiper
switch mounted on the instrument panel and is acti-
vated by pressing the knob. When the switch is acti-
vated, washing solution is pumped through the outlet
hose (3) and fed to a jet located in each of the wind-
shield wiper arms.
Service
If windshield washer maintenance is required, check
the strainer opening for obstructions and inspect the
hoses for damage. Check the voltage to the pump
from the control switch. If the pump is inoperable,
replace it with a new pump assembly.
Note: The pump is only available as an assembly
and cannot be repaired.
