- Page 2 TorcUP Inc. is not responsible for customer modification of tools for applications on which TorcUP Inc. was not consulted.
- Page 3 Avoid sharp bends and kinks that will cause severe back-up pressure in hoses an 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 To change the direction of rotation for model 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 model TU-20, TU-27 & TU-60, loosen and remove the square drive retaining screw 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 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 out-doors 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.
