Service
Determining the hydraulic pressure
Diagnostics window of the Service display shows the current
pressure of the machine. See Service display page 64.
Idling pressure or circulation pump pressure
The pump provides idling pressure when none of the
machine functions have been activated. The hydraulic oil
flows through the control valve into the container.
Measuring:
Current hydraulic pressure can be monitored from
diagnostics section of the Service display.
If the Service display doesn’t provide the data, the pressure can be measured manually.
• Measuring point PX is located on the right hand side of the tower.
• Remove the protective cover from the PX measuring point and connect the pressure gauge.
• Circulation pump pressure should be 20 bar.
• Adjust the pressure from the pump LS-adjuster.
Measuring the maximum pressure
The maximum pressure occurs when a function is set to the extreme position.
Measuring:
• Maximum pressure is measured the same way as idling pressure (above).
• When measuring the pressure of the breaker line, remove the breaker hoses before measuring.
• Movement specific maximum pressures can be found from the chart below.
• Adjust the correct pressure from the control valve. (See Adjusting the hydraulic pressure, page 43)
Measuring the supply pressure
• Connect the test nipple of the pressure gauge to the measuring point PS of the control valve.
• The supply pressure of pilot valves is automatically 35 bars, which is generated with an integrated
decompression valve.
• Can be checked by installing a pressure measuring nipple to the PS terminal of the rear end.
