In order to avoid any damage to your tool, never regulate it below 10 newton meter
1. Hold the wrench so that the direction arrow and the scale are visible.
2. Unblock the knurling knob by loosening the rear locknut anti-clockwise.
3. Rotate the knurling knob clockwise until you are near the desired scale value.
4. Proceed as follows:
- for values of 10 –18 – 42 Nm
- for values of 55 – 65 – 75 Nm
100 Kg x cm (10 Nm)
180 Kg x cm (18 Nm)
420 Kg x cm (42 Nm)
550 Kg x cm (55 Nm)
650 Kg x cm (65 Nm)
750 Kg x cm (75 Nm)
*For different torque values you can start from tabulate value and increase or decrease torque by
rotating the knob considering each dent corresponds at 10 Kg x cm (10 Nm).
5. Block the torque regulation by screwing the locknut again.
When you reach the desired tightening torque, you will hear a click and the screwing will be easier.
-
In order to avoid any damage to your tool, stop bringing pressure on the wrench after you have reached
the desired tightening torque.
-
Always bring the wrench back to the minimum values after use, in order not to damage the tightening
precision.
-
In case you have not used the wrench for a long period of time, make a few clicks with the torque at the
scale lowest value, so that the wrench can lubricate.
The fork face with the number on it must be on the same level as the direction arrow and as the
-
scale, as shown on the drawing.
