AXLE OIL TEMPERATURE CAUTION LAMP
This lamp (1) lights up to warn the operator that the brake oil
temperature has risen.
During checks before starting (when the starting switch is turned to
the ON position but the engine is not started), this monitor does not
light up.
During operation (engine running)
In continuous heavy-duty operations or when traveling long
distances downhill where the brake is used frequently, the axle oil
temperature becomes high, so the axle oil temperature caution
lamp and central warning lamp light up and the alarm buzzer
sounds intermittently.
At the same time, "E02" and "BRAKE OVERHEAT" are displayed on the character display in turn, so take the
following action.
1. Release the accelerator pedal and move the speed range selector switch down one range to reduce the travel
speed.
2.
Avoid using the brake.
1) Do not keep the brake pedal depressed continuously; use the brake only intermittently.
If use of the brake is reduced for a short time in the way recommended above, the axle oil temperature will go down
and the caution lamp will go out.
