SETTING TORQUE

All Atlas Copco power packs operate at a pressure range from 500 to 10,000 PSI and are fully adjustable.

They have been engineered and designed for portability and high flow for increased speed. Before using your

Atlas Copco power pack, check the following points.



Is the reservoir filled with oil?



Where is the closest electrical outlet at the job site?



Is there enough air pressure (60 to 100 PSI) and Air flow at the job site? (Air units only)



Is the gauge mounted and rated for 10,000 PSI/700 bar?

WORKING PRESSURE

The pump's maximum working pressure is 10,000 PSI / 700bar. Make sure all hydraulic equipment and

accessories are rated for 10,000 PSI / 700bar operating pressure. Hydraulic pumps are available with higher

pressure outputs, if not using an Atlas Copco power pack verify maximum operating pressure of the unit being

used and ensure the system maximum operating pressure (10,000 PSI / 700 bar) is not

HYDRAULIC CONNECTIONS

Never disconnect or connect hydraulic hoses or fittings without first unloading the wrench. Unplug the electrical

cord of the pump, and open all hydraulic controls several times to assure that the system has been

depressurized. If the system includes a gauge, double check the gauge to assure pressure has been released.

When making a connection with quick disconnect couplings, make sure the couplings are fully engaged

threaded connections such a fittings, gauges etc. must be clean and securely tightened and leak free.

CAUTION: Loose or improperly threaded couplers can be potentially dangerous if pressurized,

however, severe over tightening can cause premature thread failure. Fittings need to be only tightened

secure and 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. Do not subject the hose and potential hazard

such as sharp surfaces, extreme heat or heavy impact. Do not allow the hose to kink and twist. Inspect

the hose for wear before it is used.

ELECTRICAL POWER

CHECK FOR PROPER ELECTRICAL SUPPLY BEFORE CONNECTING.

THIS MOTOR MAY SPARK. DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE OR IN PRESENCE

OF CONDUCTIVE LIQUIDS.

Do not use a power or extension cord that is damaged or has exposed wiring.

All single phase motors come equipped with a three prong grounding type plus to fit the proper

grounded type electrical outlet. Do not use a two prong ungrounded extension cord as the pump's

motor must be grounded.

Compare motor nameplate against power availability to prevent motor burnout or dangerous electrical

overloading.

4.5

PRIOR TO USE

Check hydraulic oil (Use Grade 46) level to prevent possible pump burnout. Open the filler plug located on the

reservoir plate. Look at oil fill level on the oil sight gauge. The oil level should be approximately 2" from the top

of the reservoir plate- with motor off. Add oil as necessary. Do not mix different grades of oil. Make sure all

desired gauge, valve, hose and quick coupler connections are tight and secure before operating. The use of a

pressure gauge is required for normal pump operation. Mounted on the manifold, the gauge permits the

operator to monitor the load on the wrench. Class1 certified calibrated gauges are available for most

applications.
