Pump Startup

Make sure the reservoir and circuit are clean and free of dirt and debris prior to filling with hydraulic fluid.

Fill the reservoir with filtered oil to a level sufficient to prevent vortexing at suction connection to pump inlet. It is good practice to clean the system by flushing and filtering using an external slave pump.\Before starting the pump, fill with fluid through one of the ports. This is par- ticularly important if the pump is above the fluid level of the reservoir.
