Connect the air supply to the ¼” F-NPT port at the rear of the pump.
The air supply should be at least 20 CFM (.57 m³/min) and 100 PSIG
(7 BARG) to obtain the rated hydraulic pressure. Air pressure must
be regulated to no more than 120 PSIG (8.3 BARG) maximum.
2.1. Bleeding the system
With no load on the system, the Pump properly vented, and
positioned higher than the Ram, cycle the system several times.
Check the reservoir to ensure proper fluid level; fill as required.
3. TESTING
3.1. Test Ram/Pump set-up
To operate/verify Ram/Pump set-up, step on the end
of the pump pedal marked "PUMP"
while
watching the Hydraulic Ram. Within a few seconds,
the Ram should begin to stroke. Note that the piston
strokes out of the back of the hydraulic Ram. If the
Ram does not stroke, check all connections, the oil
level and repeat this step.
Proper operation will be indicated by cylinder of the
ram extending 1” – 3” (25.4 to 76.2 mm) (model
dependent) followed by the pressurization indicated on
the gauge increasing to 7500 PSIG (517 BARG).
3.2. Release Pump pressure
While holding the Ram handle step on end of the
Pump Pedal marked "
RELEASE
".
This will
allow the piston of the Ram to retract.
To remove the pneumatic power to the equipment,
disconnect the pneumatic quick connect.
