DESCRIPTION
This Air/Hydraulic Pump supplies hydraulic fluid pressure to selected tools. It consists of an in-line air and hydraulic cylinder. The
ratio of hydraulic fluid pressure generated compared to supply air pressure is 100:1.
In other words, 100 PSI out for every 1 PSI in – 100 PSI input air pressure equals 10,000 PSI output pressure.
Depressing the RELEASE pedal causes a decrease in pressure and pressing the PUMP end of the pedal provides fluid pressure.
BEFORE USE
To prevent oil leak during shipment, a metal knob is installed and tightened to ensure the best sealing
function. Loosen it counterclockwise before use.
Note: Always secure threaded port connections with non-hardening pipe thread compound. Tighten securely to prevent accidental
removal of components while in use. Take care not to introduce compound into part orifices. Familiarize yourself with the
specifications and illustrations in this operator's manual. Know your pump, it's limitations and how it operates before attempting to
use. Refer to the Specification Chart for details of oil port thread size, usable oil capacity, and more
OPERATION
Operation of the unit is as follows:
1.
Connect the hose of the Air/Hydraulic Pump to the hydraulic coupling on the selected tool.
2.
Connect the air supply line to the Air/Hydraulic Pump. Air supply should be 5-10 CFM at 100 PSI to obtain proper
operating characteristics. In addition, the air line should be equipped with an airline filter.
3.
Stepping on the PUMP end of the pedal engager the pump, producing the force necessary to run the tool.
4.
Depressing the RELEASE end of the pump pedal will release the pressure.
MAINTENANCE
1.
Inspect hoses and connections daily.
2.
Tighten connections as needed. Use non- hardening pipe thread compound when servicing connections.
3.
Use only good quality hydraulic fluid. We recommend AW- 32 WEIGHT OIL.
When not in use or during storage:
a.
Depressurize and disconnect hydraulic hoses from application.
b.
Wipe clean, thoroughly.
c.
Store in clean, dry environment. Avoid temperature extremes.
d.
Shield pump with a protective cover.
Adding Hydraulic Fluid
1.
Depressurize and disconnect hydraulic hose from application.
2.
With pump in it's upright, horizontal position, remove the oil filler plug located on the top plate of the reservoir.
3.
Use a small funnel to fill reservoir to within 3/4" (19mm) of the opening.

WARNING
The air/hydraulic pump is capable of generating fluid
pressure up to 10,000 PSI. Make certain the tool in
use is held securely and is in proper working condition.
DO NOT continue to operate the pump once the work is
Completed. Failure to comply with these instructions
Could result in personal injury or damage to the
equipment.
