- Unscrew the lock nut from the bottom of the handle and release the spring.
- Rotate the knob so that the 0 mark on the additional scale coincides with the horizontal line of the main scale related to the corresponding value. If the desired value is not on the scale, turn the knob a few divisions.
- After setting the force range, tighten the lock nut.
- Tighten the fastener until it clicks. When a characteristic sound is heard, it means that the bolt is tightened to the specified limit.
After work, unscrew the lock nut, loosen the spring.
