JCB Torque Wrench - 1/2" Drive - 20-120Nm

Rotate the handle to align the desired Newton-meter (Nm) value on the main scale with the indicator mark. Ensure the handle is locked after setting the desired torque.

Returning the wrench to its lowest torque setting (20 Nm) helps to relax the internal spring mechanism, maintaining its accuracy and extending its service life.

For professional use, annual calibration is recommended. For less frequent use, recalibrate if you notice inconsistent readings or after any accidental drops or significant impacts.

It is not recommended to use a torque wrench for loosening fasteners, as this can damage the internal mechanism and affect its accuracy.

The primary benefit is ensuring fasteners are tightened to the precise specification required, preventing damage from over-tightening or failure from under-tightening, thus ensuring safety and component longevity.

The torque range is from 20 Nm to 120 Nm.

This wrench features a 1/2" drive size.

Ensure the torque setting is above the lowest value and that you are applying smooth, continuous force. Check if the drive head is properly engaged with the socket.

Ensure the handle locking mechanism is disengaged. Clean the handle area if there is any debris preventing smooth adjustment.

The wrench may require recalibration. Ensure you are applying force smoothly and steadily. Check for any damage to the wrench mechanism.
