GeneralFollow this procedure when starting-up a new Series 45 installation or when restarting an installation inwhich the pump has been removed.W WarningUnintended movement of the machine or mechanism may cause injury to the technician or bystanders.To protect against unintended movement, secure the machine or disable / disconnect the mechanismwhile servicing.Prior to installing the pump, inspect for damage incurred during shipping. Make certain all systemcomponents (reservoir, hoses, valves, fittings, heat exchanger, etc.) are clean prior to filling with fluid.Start-up procedure1. Connect the pump to the prime mover. Ensure that pump shaft is properly aligned with the shaft ofthe prime mover.C CautionIncorrect shaft alignment may result in damage to drive shaft, bearings, or seal which can causeexternal oil leakage.2. Fill the reservoir with recommended hydraulic fluid. Always filter fluid through a 10 micron filterpouring into the reservoir. Never reuse hydraulic fluid.3. Fill the main pump housing with clean hydraulic fluid. Pour filtered oil directly into the upper mostcase drain port.4. Fill the inlet line leading from the pump to the reservoir. Check the inlet line for properly tightenedfittings and be certain it is free of restrictions and air leaks.5. To ensure the pump stays filled with oil, install the case drain line in the upper most case drain port.6. Install a gauge at port M2 (or equivalent system pressure measurement port if M2 not present) tomonitor system pressure during start up.Follow recommendations in the vehicle / machine operator’s manual for prime mover start upprocedures.7. While watching the pressure gauge installed at M2 or equivalent system pressure measurement port,jog the prime mover or run at the lowest possible speed until system pressure builds to normal levels(minimum 11 bar [160psi]). Once system pressure is established, increase to full operating speed. Ifsystem pressure is not maintained, shut down the prime mover, determine cause, and take correctiveaction. Refer to Troubleshooting on page 19.8. Operate the hydraulic system for at least fifteen minutes under light load conditions.9. Check and adjust control settings as necessary after installation. Refer to Adjustments on page 22.10. Shut down the prime mover and remove the pressure gauge. Replace plug at port M2 or equivalent.11. Check the fluid level in the reservoir; add clean filtered fluid if necessary.The pump is now ready for operation.Service ManualSeries 45 Frame K and L Open Circuit Axial Piston PumpsInitial start-up procedures© Danfoss | August 2016 520L0532 | AX00000040en-US0401 | 17
