Operating Instructions
Form No. 105001
Hydraulic Connections
Clean all 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. Remove the thread protectors from
the hydraulic fluid outlets. Connect the hose assembly to the hydraulic fluid outlet and couple the hose to the cylinder.
See illustrations below.
IMPORTANT: Seal all external pipe connections with a high-grade, nonhardening thread sealant. Teflon tape
may also be used to seal hydraulic connections, provided only one layer of tape is used. Apply the tape
carefully, two threads back, to prevent it from being pinched by the coupler and broken off inside the system.
Any loose pieces of tape could travel through the system and obstruct the flow of fluid or cause jamming of
precision-fit parts.
For Hand/Foot Operated Pumps:
For Manual Valve Operated Pumps:
This pump is equipped with a two position, 3-way/4-way control valve for operating single- or double-acting hydraulic
cylinders and requires attaching the hoses in the following manner:
When using a single-acting cylinder,
attach one end of a hose to port "A" of valve and the end of the hose to the
advance port "C" of the cylinder. Then install a pipe plug in valve port "B." If the hoses are frequently connected and
disconnected, quick couplers should be used to prevent wear and tear on the fittings.
When using a double-acting cylinder,
attach one hose to port "A" of valve and the other end of the hose to the
advance port "C" of cylinder. Attach the second hose to valve port "B" and the other end of the hose to return port "D"
of cylinder.
