  • Page 3: Working Pressure

    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. HYDRAULIC CONNECTIONS Our hydraulic pumps are equipped with a zero-pressure relief valve.

  • Page 4: 3:1 General Setup

    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.

    The reaction arm for all RT Monobloc Housing is splined to slide over the rear (cylinder) portion of the tool. In operation, the reaction arm must be fully engaged and secured by inserting the spring loaded reaction arm lever at the base of the housing ( End Cap ). Ensure the reaction is fully engaged prior to operation.

    Should the tool "lock-on" after the final cycle, push down on the remote control button once more (to build pressure) and, while maintaining this pressure, pull back on the external disengagement lever (RT) or reaction Pawl (RTX). Releasing the remote control while continuing to hold back on the pawl lever/reaction pawl will allow the tool to be removed easily.

  • Page 7: Setting Torque

    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.

  • Page 8: Operation

    OPERATION Before starting your electric Panther Pump, connect your hydraulic hoses to both the pump and torque wrench. To start the pump, press briefly the white button on the remote control.

    DRIVE SIZE: The square or hex drive of each drive is limited in its maximum output by its material and its engagement area. Since Atlas Copco uses a specially suited alloy-steel for its drive members, the following maximum torque output can be achieved without drive failure, provided the reaction member abuts close to the same plane as the nut to be turned.
