Operations Manual
Changing Drive Direction (continued)
To change direction insert the drive to the opposite side of the tool end
removed. Gently turn the square drive until it can be engaged in the spline and
pushed in. Depress the drive retainer button, engage the button with the drive
retainer and release the button locking the square drive into position.
Reaction Arm
All Hydraulic Torque Wrenches are equipped with universal reaction arms.
The reaction arm is designed to absorb and counteract forces created as the
Hydraulic Torque Wrench operates. The reaction arm should extend in the
same direction as the square drive, however slight adjustments can be made to
suit each particular application. Reaction arms rotate 360 degrees.
Setting the Torque
Ensure the Hydraulic Torque Wrench being used has been calibrated and
checked within the manufactures guidelines.
Once the Hydraulic Torque Wrench is fully connected and power or air supply
confirmed, the operator may now adjust the pressure to the required torque
setting.
When tightening, refer to the manufactures torque setting and bolt tightening
sequence requirements. Bolt pattern and tightening sequence can vary
between different manufactures or gasket materials.
Torque settings vary between different manufactured Hydraulic Torque
Wrenches. Refer to the relevant manufacturer Hydraulic Torque Wrench
Tension Chart. Different sized Hydraulic Torque Wrench’s, for example ¾ drive,
1 drive, 1 ½ drive and 2 ½ inch drive, all have different torque charts. Ensure
you use the correct chart for the Hydraulic Wrench being used.
