EXPLANATION OF COMPONENTS
HYDRAULIC OIL TEMPERATURE GAUGE
• To display the hydraulic oil temperature indicator the rear camera needs to be deactivated. To deac-
tivate it, engage the travelling on street mode or put the controls locking lever to L (LOCK).
For more details, see "STREET MODE SWITCH (3-51)" and "CAMERA IMAGE SELECTOR SWITCH
(3-55)"
• Check the oil temperature when the machine is not carrying out any work and afterwards start the
camera again before using the machine.
Hydraulic oil temperature gauge shows the hydraulic oil tem-
perature.
If the indicator is in green range during operations, it is normal.
When the indicator comes close to (A) of the red range during
operation, the hydraulic oil temperature has exceeded 102 °C.
Then run the engine at low idle or stop it and wait for the oil
temperature to drop.
(A) to (B): Red range
(A) to (C): Green range
(C) to (D): White range
REMARK
When the indicator reaches red range (A), the hydraulic oil temperature is as follows.
Red range (A) position: 102 °C or more
Red range (B) position: 105 °C or more
When the indicator is in red range (A) to (B), hydraulic oil temperature caution lamp (E) indicates abnormality.
When the engine is started, if the indicator is at position (C), the hydraulic oil temperature is below 20 °C and
hydraulic oil temperature caution lamp (E) indicates low temperature. In this case, perform warm-up operation.
For details see "METHOD FOR HYDRAULIC SYSTEM WARM-UP OPERATION (3-156)".
Display (G) when temperature is low: Caution lamp background
(K) is white.
Display (H) when temperature is proper: Caution lamp back-
ground (K) is blue.
Display (J) when condition is abnormal: Caution lamp back-
ground (K) is red.
FUEL GAUGE
Fuel gauge shows the amount of fuel in the fuel tank.
The indicator should be in the green range during operations.
If the indicator starts to enter red range (A) during operation,
the remaining fuel is 32 ℓ or less, so perform inspection and
add fuel.
(A) to (B): Red range
(A) to (C): Green range
