3.4 ATC
The power tool is equipped with the ATC (Active Torque Control) quick-
acting electronic cut-out.
If the accessory tool sticks or stalls, the power tool will suddenly pivot about
its own axis in the opposite direction. ATC detects this sudden pivoting
movement of the power tool and switches the tool off immediately.
For ATC to function correctly, the power tool must be free to pivot.
After the power tool has cut out due to ATC, switch it back on again by
releasing the control switch and then pressing the switch again.

The Li-ion battery state of charge and malfunctions of the power tool are
indicated by the display on the Li­ion battery. The Li­ion battery state of
charge is displayed after pressing one of the two battery release buttons.
