2. DEF (AdBlue
®
) Level Gauge
This gauge indicates the amount of DEF remaining in the
DEF (AdBlue
®
) tank.
White range - Normal amount of DEF.
Red range - Not enough DEF.
If the needle moves into the red range, the SCR error
warning indicator activates.
In such cases, be sure to stop the engine and add DEF
immediately. Check the DEF level on firm, level ground.
3. Engine Coolant Temperature Gauge
This gauge indicates the temperature of the engine coolant.
C range - Overcooled or initial start-up period.
H range - Engine is overheated.
The needle must remain in the white range while the
machine is in operation.
If the needle moves into the red range, the engine coolant
temperature warning indicator turns on, the warning buzzer
sounds and the engine speed decreases automatically.
Operate the engine at the "lowest engine speed" until the
temperature gauge returns to the white range. Once the
gauge reaches the white range, idle the engine for another
3 ~ 5 minutes before stopping the engine.
Failing to idle the engine may damage the engine due to a
sudden increase in temperature. Idling the engine releases
heat. Check the coolant level; check whether the fan belt is
loose; and check for any debris near the radiator.
Once the temperature reaches the normal range, the engine
speed returns to normal automatically.
4. Hydraulic Oil Temperature Gauge
This gauge indicates the temperature of hydraulic oil.
C range - Low hydraulic oil temperature.
H range - Hydraulic oil is overheated.
The needle must remain in the white range while the
machine is in operation.
If the needle moves into the red range, the hydraulic oil
temperature indicator activates.
Operate the engine at the "lowest engine speed" until the
temperature gauge returns to the white range.

indicator and other indicators, please refer to "22.
