K. HYDRAULIC FLUID TEMPERATURE GAUGE
The gauge shows the hydraulic oil temperature. The operating normal temperature is within the green area.
When the hydraulic oil temperature rises, the gauge goes to the yellow area, the warning alarm sounds for
3 seconds, and the master warning indicator changes to yellow. When the temperature continues rising, the
gauge goes to the red area and the warning alarm sounds continuously. The master stop indicator becomes
red. The machine MUST NOT be operated when the temperature is in the red area.
