Operating Instructions
Hydraulic Connections
1.
It is necessary to vent the pump before using it.
Loosen the oil fill knob by turning it counterclockwise.
(The oil fill knob was installed and tightened to prevent the oil from leaking during shipment.)
2. Clean all the areas around the fluid ports of the pump and cylinder.
3. Inspect all threads and fittings for signs of wear or damage, and replace as needed.
4. Clean all hose ends, couplers, and union ends.
5. Remove the thread protector from the hydraulic fluid outlet. Connect the hose assembly to the hydraulic
fluid outlet, and couple the hose to the cylinder.
Important: Seal external pipe connections with high-grade thread sealant.
Air Connections
