Operating modes

The descriptions of the individual operating modes below apply only to forward rotation of the impact
wrench (tightening). In reverse (slackening), the action of the impact wrench is not controlled.
5.6.1

Adaptive operation

In this operating mode the adaptive torque module regulates the tightening of the selected type of threaded
fastener. The tightening parameters from the most recently installed software update are used. Product
designations and tightening parameters can change, so it essential to ensure that the software version
installed in the torque module is always up to date.
• When the "Adaptive" operating mode is selected, the impact wrench's "AT" torque indicator lights up.
• The switch for selecting the operating stage is not active. But you can use the control switch to turn the
impact wrench ON and OFF.
Follow the operating instructions for your impact wrench.
