WORKING PRESSURE
The tool's maximum Working Pressure is 10,000 PSI (700 bar). Make sure that all hydraulic equipment (pumps,
hoses, couplers) used with this tool are rated for 10,000 psi (700 bar) working Pressure. Review the
documentation for the hydraulic pump in use to ensure pressure does not exceed 10,000 psi.
2.2
HYDRAULIC CONNECTIONS
Our hydraulic pumps are equipped with a zero-pressure relief valve. However, it could be possible that the
retract side remain pressurized after the pump has been switched "off". This trapped pressure prevents the
user from loosening the retract-side fittings by hand. To release the pressure, simply push the black button on
top of the solenoid. All fittings are free to be manually tightened.
Never disconnect or connect any hydraulic hoses or fittings without first unloading the wrench and the pump.
If the system includes a gauge, double check the gauge to assure pressure has been released. When making
connections with quick disconnect couplings, make sure the couplings are fully engaged. Threaded
connections such as fittings, gauges etc. must be clean and securely tightened and leak free.
CAUTION: Loose or improper threaded fittings can be potentially dangerous if pressurized. Severe over
tightening can cause premature thread failure. Fittings need to be only tightened secure & leak free. Never
grab, touch or in any way, come in contact with a hydraulic pressure leak. Escaping oil can penetrate the skin
and cause injury.

ELECTRICAL CONNECTIONS
Ensure proper power availability to prevent motor failure or dangerous electrical overloading. Use the
recommended amperage listed on the motor nameplate. Do not use electric pump if ground is not connected
on plug.
Minimize the length of extension cords and be sure they are of adequate wire size, with ground connections.
Extension cord should be #10 AWG gauge.
WARNING: Electric motors may spark. Do not operate in an explosive atmosphere or in the presence of
conductive liquids. Air driven pumps are better suited for these applications.
2.4
AIR CONNECTIONS
Ensure that you have sufficient air flow
(58 up to 100 PSI / 4 up to 7 bar) to
operate you pneumatic pump. If in
doubt, compare the pump
manufacturer's recommended air flow
rating prior to pressurizing pump.
Improper air flow may damage the pump
motor.
For best results use air hoses equal or
larger than 3/4" internal diameter.
Use of a F.R.L. (Filter Regulator
Lubricator) is highly recommended. Fill
with oil and adjust the air admission with
the adjustment knob.
