3.2 Explanation of components Operation
3-20 WA470-6H – VEAM946100
1. Axle oil temperature caution lamp
This lamp (1) lights up to warn the operator that the axle oil tem-
perature 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 dis-
tances 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, the top line of the character display displays
“E02“ and the bottom line displays “BRAKE OVERHEAT“, 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.
" Do not keep the brake pedal depressed continuously;
use the brake only intermittently.
" When using the left brake pedal, turn the transmission
cut-off switch ON to carry out operations.
If use of the brake is reduced for a short time in the way recom-
mended above, the axle oil temperature will go down and the
caution lamp will go out.
2. Torque converter oil temperature caution lamp
This lamp (2) lights up to warn the operator that the torque con-
verter 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)
If the torque converter oil temperature rises, the torque con-
verter oil temperature caution lamp only will light up.
If the oil temperature rises further, the central warning lamp will
light up and the alarm buzzer will sound intermittently.
At the same time, “E02“ is displayed on the top line of the char-
acter display and “TC OVERHEAT“ is displayed on the bottom
line. Stop the machine and run the engine under no load at a
mid-range speed until the lamp goes out.
