SET-UP
Hose Connections
1. Clean all areas around the oil ports of the pump and cylinder.
2. Inspect all threads and fittings for signs of wear and damage. Replace as needed. Clean all hose ends, couplers,
or union ends.
3. Remove thread protectors from hydraulic oil outlets. Connect the hose assembly to the hydraulic oil outlet, and
couple the hose to the cylinder.
IMPORTANT: Seal all pipe connections with an approved thread sealant. Teflon tape can also be used to seal
hydraulic connections if only one layer of tape is used. Apply the tape carefully to prevent it from being
pinched by the coupler and broken off inside the pipe end. Any loose pieces of tape could travel through the
system and obstruct the flow of oil or cause jamming of precision parts.
4. Refer to Figure 1.
OPERATION
a. If your pump has a
two-way, three-way or automatic
valve,
attach one end of the hose to port "C" and the
other end of the hose to advance port "B" of the cylinder.
b. If your pump has a
four-way valve
for operating double-
acting cylinders, attach one hose between the upper port
"A" on the pump and the return port "D" of the cylinder.
Attach a second hose between the lower port "C" on the
pump and the advance port "B" on the cylinder.
1. Open the filler plug two full turns to vent the reservoir.
2. Place the control valve in the neutral position. (Refer to the
following information about valves.)
3. Insert the power cord into an outlet.
WARNING: To help prevent personal injury, check the
voltage rating on the motor nameplate to be sure the outlet
has the right voltage.
Priming The Pump
1. Back the priming screw out two complete turns. See Figure 2.
2. Jog the pump three times.
3. Tighten the priming screw to 15-25 in. lbs.
Two-Way Valve
(use with single-acting cylinders)
1. Turn the valve handle all the way clockwise. Back the handle
out until it reaches the stop. Always start the pump in this
neutral position.
2. Using the toggle switch, jog the motor several times. Place the
switch on RUN, and let the pump idle for a few minutes.
3. To advance the cylinder, turn the valve handle in all the way
clockwise. See Figure 3.
4. To retract the cylinder, turn the valve handle counterclockwise
until it reaches the stop. See Figure 3.
5. Place the cylinder at a lower level than the pump. Advance
and retract the cylinder several times to remove air from the
hydraulic system.
