  • Page 3: Failure To Observe The Following Warnings Could Result In Injury

    Avoid sharp bends and kinks that will cause severe back-up pressure in hoses and lead to premature hose failure. • Use accessories recommended by TorcUP. • Use only impact sockets and accessories. Do not use hand (chrome) sockets or accessories.

  • Page 4: Setting The Torque

    To change the direction of rotation for models TU-2 TU-3, TU-7 and TU-11 simply push the square drive into the housing until the drive projects out the opposite side of the tool. For models TU-5, TU-20, TU-27 and TU-60, loosen and remove the square drive retaining knob and pull the square drive out of the housing.
  • Page 5 SETTING THE REACTION ARM The function of a reaction device is to hold the tool in position against the forces generated to tighten or loosen bolts or nuts. Hydraulic wrenches generate tremendous force. An improperly positioned reaction arm may result in operator injury or damage to tooling.

  • Page 6: Operating The Wrench

    OPERATING THE WRENCH Square Drive Position for Loosening and Tightening (Dwg.02) The position of the square drive relative to the shroud determines whether the action will tighten or loosen the nut. (Refer to Dwg. 02 for application examples). The power stroke of the piston assembly will always turn the square drive toward the shroud.
  • Page 7 LUBRICATION MARINE MOLY GREASE Lubrication frequency is dependent on factors known only to the user. The amount of contaminants in the work area is one factor. Tools used in a clean room environment will obviously require less service than a tool used outdoors and dropped in loose dirt or sand. Marine Moly Grease is formulated not to wash out of the tool in areas where lubrication is critical.
