To prevent accidental changes in the set torque, the 666N dynamometer key is equipped with a safety knob. To change the pair it is necessary to pull the knob until the red colored band is visible. In this position you can rotate the handle and set the desired torque on the reading scale. Once this operation is finished, it is necessary to push the safety knob to the handle to lock the key and proceed with the lock.
