OPERATION
PICTOGRAM DEFINITIONS
Activating the pump with the pedal end marked with this pictogram,
the flow of fluid is directed out of the reservoir.
Activating the pump with the pedal end marked with this pictogram,
the flow of fluid is directed back to the reservoir.
Priming The Pump Unit
Under certain circumstances it may be necessary to prime the pump unit. To accomplish this, perform the following
procedure:
For Hand/Foot Operated Pumps:
1. Press the release end of the pedal while holding down the air intake
valve with a flathead screwdriver. The air intake valve is located directly
under the pedal in the area marked . The valve is depressed
simultaneously with the area of the pedal during priming.
2. Allow the pump to cycle approximately 15 seconds.
3. Remove the screwdriver, and press the end of the pedal once
more.
4. If the cylinder extends or pressure builds, the pump has been
successfully primed. If the pump does not respond, repeat the procedure,
jogging the air intake valve while holding the pedal in the position.
For Manual Valve Operated Pumps:
Disconnect the hose end at the advance port of the cylinder. Direct the hose
end into a suitable container or back into the pump reservoir. Shift the valve
to the ADVANCE position and depress the end of the foot pedal inscribed
with . Allow the pump to cycle until fluid begins to flow freely into the
container or reservoir. Reconnect the hose end to the cylinder advance port.
Shift the valve to the ADVANCE position and reactivate the pump. If the
cylinder extends or builds pressure, the pump has been successfully primed.
If not, refer to the Trouble-shooting Guide of these instructions.
For Remote Controlled Pumps:
Depress the AND buttons on the remote hand control simultaneously and allow the pump to cycle for
approximately fifteen seconds. Release both buttons and then depress the button once more. If the cylinder
extends or pressure builds, the pump has been successfully primed. If the pump does not respond repeat the
procedure. If pump still does not respond, tip pump upside down and repeat procedure.
For Tandem Pumps:
1. Connect the fluid line to the pressure port and keep the return port plugged. Place the other end of the fluid line in
the pump filler hole.
NOTE: If the fluid lines are connected to a remote valve, shift the valve into the
center position and plug both cylinder ports on the valve. This lets fluid circulate
through the valve and back to the pump reservoir; thereby allowing the pump to prime.
2. Attach air line with shut-off valve to the pump.
3. Open the air valve. Pump will begin to reciprocate, and fluid will advance
through the hose or fluid line and return to the pump reservoir. Allow the
pump to cycle approximately 15 seconds.
4. Plug the manifold pressure port, or shift the valve to pressurize the circuit.
If the pump builds pressure, it has been successfully primed.
