Hydraulic Oil Temperature Gauge
Hydraulic oil temperature gauge (23,
Figure 5-7) indicates oil temperature
in the hydraulic tank. There are two
colored bands: green and red.
Green indicates normal operation.
As the needle approaches the red zone, minimum
engine idle speed will increase to help cool the oil.
Red indicates high oil temperature in the hydraulic
tank. Continued operation could damage compo-
nents in the hydraulic system. There is also a red
temperature warning light in the overhead panel (A1,
Figure 5-8) that will illuminate when the temperature
exceeds a certain level (when the needle enters the
red zone). If this condition occurs, the operator
should safely stop the truck, move the directional
control lever to PARK, and operate engine at 1200 -
1500 rpm to reduce system temperature.
If temperature gauge does not move into the
green range after a few minutes, and the red
overhead indicator light does not go out, stop the
engine and notify maintenance personnel imme-
diately.
