1. Make sure the pump is on a level surface.
2. Connect Foot Pump to an external air source that is capable of supplying 90 PSI @ 10 CFM. Next
c
onnect a 3/8” NPT quick disconnect coupler or hose to the oil outlet side
that is rated for 10,000
psi. (PowerX recommends that a gauge adaptor and 10,000 PSI gauge be used during operation).
Connect the pump to tooling (I.e. cylinder, bender, or cutter)
3. Check for leaks in system and repair as needed. Before repairs are made, disconnect air source
and application, then release the pressure from the hydraulic system. Do so simply by pressing the
pedal or pendant button for three seconds (see figure 1).
4.
To build pressure, depress the pedal or pendant button where “PUMP” is located. Operate pump
until desired position is reached and/or pressure is obtained (see figure 1).
5. To retract a cylinder, simply press down on the RELEASE valve or pendant button portion of the
pump. Fully depressing pedal will LOCK the DETENT feature to “on” (see figure 1).
6. For double acting pumps model

, to build pressure depress were indicated (see figure 1).
When the handle is in the center position, the load will not move even if the pump is running. To
actuate the load, start the pump, rotate the handle in either direction to extend or retract the load.
Move the handle back to the center position and release the treadle to stop the pump. Always move
the valve handle to the center position before stopping the pump.
WARNING:
If the pump is stopped and the valve is not in the center position it is possible for
the load to drift or lower. See section 2.0, Safety.
