Abstract (en)

[origin: WO2015193022A1] The invention relates to a method for operating a power tool (10) for screwing a screw (61) into a workpiece (110). After the power tool is activated, an electric motor (20) is driven in order to screw the screw into the workpiece, wherein the rotational speed of the electric motor is ascertained while screwing the screw during a specified starting time of an impact operation (t2) of the power tool. After the starting time, a rotational speed of the electric motor is ascertained, and a torque of the electric motor is at least reduced (t5) if the ascertained rotational speed of the electric motor exceeds a specified rotational speed threshold.
