Abstract
A method for operating a machine tool having a battery and an electric motor which is designed to rotationally drive an output shaft that can be coupled to a tool, is described, a control device for actuating the electric motor and a device for determining a parameter being provided. The machine tool can be operated in a first operating mode and a second operating mode, the machine tool being transferred from the first operating mode into the second operating mode if the parameter determined by the device exceeds or falls below a defined threshold value. In the second operating mode, the electric motor is controlled by an amperage profile, the amperage profile comprising first current pulses () and second current pulses (). The level of a maximum amperage (A) of the first current pulses () is greater than the level of a maximum amperage (A) of the second current pulses (). A machine tool that can be operated using a method of this kind is also described.
