FUEL GAUGE

E: The tank is empty
F: The tank is full
During operation, the indicator of the fuel gauge should be in the green
range . The control light of the fuel gauge and the central warning light
(CAUTION) start to flash, if the indicator enters the critical (red) range.
Fill up with fuel if the indicator enters the red range.
8.

ENGINE COOLANT TEMPERATURE

This measuring instrument indicates the temperature of the coolant.
During operation, the indicator lights up in the green range if the
temperature is normal. If the red range lights up, stop the machine and
run the engine at medium rpm without load until the indicator returns to
the green range.
The instrument control lights and the central warning light (CAUTION)
start to flash, if the indicator lights up in the 1st red section. An acoustic
alarm will also be issued, if the indicator enters the 2nd red section.
9.

TEMPERATURE FOR CONVERTER OIL

This measuring instrument indicates the temperature of the converter
oil. During operation, the indicator will be in the green range, if the
temperature is normal. The converter oil temperature is too high, if the
indicator is in the red range.
The instrument's control light and the central warning light (CAUTION)
start to flash, when the indicator enters the first red section. An acoustic
alarm is also issued, if the indicator enters the second red section.
The torque converter's oil can extremely heat up, if the machine is driven
in an inappropriately high gear. In this case, select the next lower gear so
that the oil temperature can cool down.
If the temperature is still too high, stop the machine, put the driving direction
lever in its neutral position and run the engine at medium speed until the
gauge's indicator has returned to the green range.
10.

OPERATING HOURS METER

The operating hours meter indicates the total operating hours. It is only
active when the engine is running and the alternating current generator is
generating power - independent whether the machine is being driven or
not.
When the engine is running, the meter's green light starts to flash indicating
that it is counting the operating hours.
