OPERATION Hydraulic Oil Temperature Gauge This meter (10) shows the hydraulic oil temperature. During normal operations, the indicator should be in the green range. If the indicator enters the red range (A) during operations, the hydraulic oil temperature is 102°C (215.6°F) or more. Run the engine at low idling or stop it and wait for the hydraulic oil temperature to go down. (A) - (B): Red range (A) - (D): Green range (D) - (C): White range Remark When the indicator reaches red range (A), the hydraulic oil temperature is as follows. Red range (A) position: 102°C (215.6°F) or more Red range (B) position:
105°C (221°F) or more When the indicator is in red range (A) - (B), hydraulic oil temperature monitor (1) shows the abnormality display. When the engine is started, if the indicator is at position (C) and the hydraulic oil temperature is 20°C (68°F), hydraulic oil temperature monitor (1) shows the low-temperature display. If this happens, carry out the warming-up operation for the hydraulic equipment. For details, See “Engine Warm Up” on page 2-139.
