1. Filling The Pump Reservoir.

Most pumps are shipped without hydraulic fluid in the reservoir. Hydraulic fluid may have been

shipped with the pump in a separate container. If hydraulic fluid is needed, use 215 SSU @ 100° F

(47 cSt @ 38° C) hydraulic fluid.

Clean the area around the filler cap to remove all dust and grit. Any dirt or dust in the hydraulic fluid can

damage the polished surfaces and precision-fit components of this pump.

Retract all cylinder(s) to their return position.

C. Remove the filler cap and insert a clean funnel with a filter. Fill the reservoir with hydraulic fluid to 1"

(25,4 mm) from the cover plate, replace the filler cap.

2. Hydraulic Connections

Remove the thread protectors or dust covers from the hydraulic ports if applicable. Clean the areas around the

fluid ports of the pump and cylinder. Inspect all threads and fittings for signs of wear or damage, and replace as

needed. Clean all hose ends, couplers and union ends. Connect all hose assemblies to the pump and cylinder.

Use an approved, high-grade pipe thread sealant to seal all hydraulic connections. Tighten securely and leak-

free but do not overtighten.

Hydraulic lines and fittings can act as restrictors as the cylinder or ram retracts. The restricting or slowing of the

fluid flow causes back pressure that slows the cylinder's or ram's return. Return speed also varies because of

the application, condition of the cylinder or ram, inside diameter of hose or fitting, length of the hose, and the

temperature and viscosity of the hydraulic fluid.

3. Bleeding The System

After all connections are made, the hydraulic system must be bled of any trapped air. Refer to the diagrams

below.

With no load on the system and the pump vented and positioned higher than the cylinder or ram, cycle the sys-

tem several times. Check the reservoir for possible low fluid level and fill to proper level with approved, com-

patible hydraulic fluid as necessary (see "Filling The Pump Reservoir" section under Set-up Instructions).
