摘要： A method for operating a hand-guided machine tool. The method contains detecting at least one linear acceleration value by means of the at least one sensor apparatus (6); subtracting the gravitational acceleration from the at least one linear acceleration value to form an adjusted linear acceleration value; integrating the adjusted linear acceleration value into a speed value; integrating the speed value into a distance value; multiplying the speed value by a time constant to form at least one further distance value; adding the distance value to the further distance value to form at least one total distance value; filtering at least one of the linear acceleration values and/or at least one of the speed values; comparing the total distance value with a defined limit value; and initiating a predefined action when the total distance value exceeds the defined limit value. A hand-held machine tool for carrying out such a method is also described.
