OPERATION
EXPLANATION OF COMPONENTS
3-13
POWER TRAIN OIL TEMPERATURE GAUGE
NOTICE
If the power train oil temperature gauge often enters the red range (C), we recommend you to lower the
travel speed one range (for example, F2
→
F1) to reduce the load on the power train when operating.
Gauge (2) indicates the torque converter outlet oil temperature.
If the temperature is normal during operation, green range (B)
will light.
If red range (C) lights up during operation, move the fuel con-
trol dial to lower engine speed to approx. 3/4 of the full speed,
reduce the load and run until the oil temperature enters green
range (B).
If red range (C) lights up during operation, and the power train
oil temperature caution lamp flashes and the alarm buzzer
sounds, stop the machine, run the engine at low idle, and wait
for the oil temperature to go down to green range (B).
(A): White range
(B): Green range
(C): Red range
HYDRAULIC OIL TEMPERATURE GAUGE
Gauge (3) indicates the hydraulic oil temperature.
If the temperature is normal during operation, green range (B)
will light.
If the red range (C) lights up during operation, move the fuel
control lever to lower the engine speed to approx. 3/4 of the full
speed, reduce the load and run until the oil temperature enters
the green range (B).
(A): White range
(B): Green range
(C): Red range
FUEL LEVEL GAUGE
Gauge (4) fuel level in the fuel tank.
During normal operation, the green range (B) should be lit.
If red range (A) lights up during operation, add fuel immedi-
ately. If this is not done, the engine speed will become irrgular
or an error display will be shown on the monitor.
(A): Red range
(B): Green range
REMARK
The display is not proportional to the amount of fuel remaining.
If only the red range (A) lights up, there is less than 60 liters of
fuel remaining.
