GENERAL SETUP

All our hydraulic torque wrenches are supplied completely assembled, ready for use. An Atlas Copco hydraulic

power pack, for use with your Atlas Copco hydraulic torque wrench, is recommended to provide the speed,

pressure and portability that make your Atlas Copco System efficient and accurate.

The accuracy of your Atlas Copco hydraulic torque wrench is +/-3% based upon our manufacturer's

specifications. This accuracy is certified through calibration tests conducted by Atlas Copco or any other

qualified calibration facility whose program is traceable to the National Institute of Standards and Technology

(N.I.S.T). We strongly suggest using Atlas Copco certified gauges (with a class 1 accuracy) to enhance the

accuracy your torquing system.

CONNECTING THE SYSTEM

The Atlas Copco hydraulic torque wrench and the power pack are connected by a 10,000 PSI (700 bar)

operating pressure twinline hose assembly. The safety ratio of the Atlas Copco Hydraulic Hose is 4/1. On each

twin hydraulic hose, one line must be MALE-MALE and the other line must be FEMALE-FEMALE in order to

assure a correct interaction between Pump and Machine. Connect the twinline hose to the swivel as shown:

IMPORTANT: Ensure connectors are fully engaged and screwed snugly together.

Never use two twin hydraulic hoses between Pump and Machine. If so, you have the high pressure on the

retract side and your machine is no able to work properly. To avoid tool malfunction, do not reverse connectors.

Do not try to loosen the swivel assembly at any moment.

WARNING: Electric motors may spark. Do not operate in an explosive atmosphere of in the presence of

conductive liquids. Air driven pumps are better suited for these applications.

OPERATING THE ATLAS COPCO RT SERIES SQUARE DRIVE

CHANGING DRIVE DIRECTION

To remove the square drive, push the round button on the drive

retainer and gently pull on the square end of the square drive (for

RT20, 25 & 50, push on the drive retainer while turning it counter-

clockwise). To insert the drive in the tool, place the drive in the

desired direction, engage drive and bushing splines, then twist drive

and bushing until ratchet Spline can be engaged.

Push drive through ratchet. Depress drive retainer button, engage

retainer with drive and release button to lock the square drive in

position.

REACTION ARM

All Atlas Copco hydraulic torque wrenches are equipped with a

universal reaction arm. These reactions arms are employed to

absorb and counteract forces created as the unit operates. The

reaction arm should extend in the same direction of the square

drive; however, slight adjustments may be made to suit your

particular application. The RT Reaction Arm is made of Special

Aircraft Alloy and is 360° adjustable.

NOTE: The standard RT reaction arm cannot be welded on and should not be modified.
