rotation, the impact wrench runs at the highest torque setting.
In this operating mode a total of 30 torque settings are available. The setting to be selected for a particular
type of tightening application depends on the diameter of the threaded fastener and the specified torque.
The setting is determined graphically on the basis of these data.
For the “Tightening” operating mode, the display shows the following:
The number to the right of the threaded-fastener symbol shows the selected setting.
5.6.2.1 Determining the required setting for the “Bolting” operating mode
1. Determine the specified torque and diameter for the bolted connection to be tightened.
Note
For the sake of clarity, examples are shown in the diagram; the arrows show the direction in which
it should be read.
Printed: 13.02.2017 | Doc-Nr: PUB / 5331875 / 000 / 00

English 13
2. Start at the required torque on the vertical axis of the applicable diagram and then move horizontally to
the right until you reach the line for the correct diameter.
3. Then move vertically downwards until you reach the horizontal axis and read the setting at this point.
Note
The curves in the diagram were determined under specific conditions. Since the conditions in
everyday use constantly vary, the values determined using the diagram should be used only as a
guide. The correct setting should therefore be determined as described below by comparison with
a conventional torque wrench.
4. Set the specified torque on a torque wrench and tighten a bolted connection using the torque wrench.
5. Mark the exact position of the bolt or nut relative to the base material.
6. Release the bolt or nut again.
7. First select a slightly lower setting on the torque module than the one indicated in the diagram.
Note
This should prevent damage to the bolted connection as a result of overtightening.
8. Now use the impact wrench to tighten the bolt or nut.
9. Check whether the bolt or nut was tightened to exactly the same extent as with the torque wrench.
Result 1 / 3
The bolt or nut was not adequately tightened
▶Release the bolt or nut and reset the torque module to the next higher setting.
▶Tighten the bolt or nut using the new setting and carry out this step of the test again.
Result 2 / 3
The bolt or nut was overtightened.
▶Release the bolt or nut and reset the torque module to the next lower setting.
▶Tighten the bolt or nut using the new setting and carry out this step of the test again.
Result 3 / 3
The bolt or nut was tightened to exactly the same extent as with the torque wrench
Printed: 13.02.2017 | Doc-Nr: PUB / 5331875 / 000 / 00

14 English
The correct setting for the bolt or nut has been determined.
5.6.3 “Unregulated” operating mode
Adaptive torque control is deactivated in this operating mode. The impact wrench then functions as though
the adaptive torque control module was not fitted to the tool. The adaptive torque module therefore does
not have to be removed for short periods of use without adaptive torque control.
