• Read and understand the installation and start-up manual
HY28-2709-02/P1/EN.

• Ensure that all necessary ports are properly connected.
• Check reservoir for cleanliness. Drain and clean as required.
• Check uid level and ll as required with ltered uid to a minimum
ISO cleanliness level of 20/18/14.
• Fill pump case with clean oil prior to starting.
• If pump is mounted vertically with the shaft up, bleed the air out the D1
drain port located near the mounting ange.
• Check alignment of drive.
• Check oil cooler and activate it, if included in circuit. Check uid temperature.
• Reduce pressure settings of compensator and relief valve. Make sure accurate
pressure readings can be made at appropriate places.
• If solenoids in system, check for actuation.
• Jog the pump drive. Check for proper shaft rotation. Make sure pump lls
properly.
• Start the pump drive.
• Bleed system of air. Recheck uid level.
• Cycle unloaded machine at low pressure and observe actuation
(at low speed, if possible).
• Increase pressure settings gradually in steps. Check for leaks in all lines
especially in pump and motor inlet lines.
• Make correct pressure adjustments.
• Gradually increase speed. Be alert for trouble as indicated by changes in
sounds, system shocks, and air in uid.
• Equipment is operational.
