Torque value 

Determine the corresponding pressure of the hydraulic power pack to achieve the 

required torque value.  

You can find this information in the Pressure - Torque Chart provided with the hydraulic 

torque wrench. 

Important  

To avoid hydraulic torque wrench malfunction: 

• DO NOT reverse connectors.

 

• DO NOT tamper with the set screw on the swivel assembly.  (It is factory preset

for safety purposes and adjustments  should only be made by trained personnel.)

 

Connect the hydraulic hose  assembly

 

to the swivel as shown below:

 

Ensure the connectors are fully engaged and screwed snugly together.
