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, it being possible for the machine tool to be operated in a first operating mode and a second operating mode, and the control device transferring the machine tool 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. The electric motor () is controlled in the second operating mode by an amperage profile comprising current pulses (), a level a maximum amperage (A, A', A) of the current pulses () being varied depending on an actual charge status of the battery (). A machine tool that can be operated using a method of this kind is also described.
