Hydraulic oil temperature gauge
The hydraulic oil temperature gauge
(2)
indicates the oil temperature of the hydraulic
system.
The normal operating temperature is in the green zone.
When the hydraulic oil temperature increases, the gauge
will move into the yellow zone, the warning alarm sounds,
and the caution master indicator turns yellow. If the tem-
perature continues to increase the gauge moves into the
red zone, the audible warning alarm will sound continu-
ously, and the stop master indicator turns red. Do not
operate the machine when the temperature is in the red
zone.

NOTICE:
To prevent damage to the hydraulic system, stop the machine, shift to neutral, and run the engine at partial
throttle, approximately
1700 RPM
until the system cools. If the hydraulic oil temperature does not return to normal
operating temperature, check the hydraulic oil level. Correct the problem before continuing to operate the machine.
