Reducing the Fluid Temperature
The hydraulic power unit (HPU) will be shut down if the hydraulic fluid reaches
a temperature of 77°C (170° F).
Note The thermometer is for reference only. Use a calibrated thermometer
submersed in the reservoir for an accurate reading.
To reduce the fluid temperature, you need to make adjustments to the heat
exchanger.
• If you have the air-cooled version go to “Adjusting the Air Flow” on page

• If you have the water-cooled version go to “Adjusting the Water Flow” on
page 23.
