Abb. 4-3
1. Hold the output drive firmly.
2. Carefully push the size 2 hex wrench through
the hole of the pistol grip housing until it
reaches the torque adjustment screw .
3. Turn the torque adjustment screw and roughly
set the required torque, see Abb. 4-1 ,
page 10.
Total number of turns = 6.
4. Pull out the hex wrench.
The hole closes automatically when the tool
starts.
5. Carry out the rundown.
6. Check the shutoff mechanism worked prop-
erly, see 4.5.3 Measuring the torque, page 12.
7. In case of deviations,
correct the torque setting
8. Repeat the rundown.
Requirement Measure
Greater shut-off accuracy –
particularly for hard joints.
Increase the number of pulses per rundown.
Recommended number of pulses
≥
6.
