Priming New Pump
To prevent cavitation or air in the hydraulic system after installing a new pump or even when flushing
the hydraulic system, make sure to prime the pump before starting the engine.
Apply the following procedure for any new installed pump:
1. Make sure the parking brake is applied and the vehicle is tagged out for maintenance purposes
(refer to “Locking Out and Tagging Out the Vehicle” on page 14).
2. With the shut-off valve closed (see Figure 5-15), fill the suction line before installing it on the
pump.
3. Fill the pump housing with new oil.
4. Reinstall the pressure hose on the pump housing.
5. Open the shut-off valve on the suction line.
Danger!
Apply the lockout / tagout procedure at all times when maintenance or inspection is
carried out on the vehicle.
