Abstract
A method is provided for operating a hand-held machine tool including a drive device, with a control device for actuating the drive device and at least two capacitive sensor elements operatively connected to the control device being provided. The method includes the following method steps of determining a first and second electrical charge of the first and second sensor element comparing the determined first electrical charge with a defined first threshold value and the determined second electrical charge with a defined second threshold value which differs from the first threshold value; enabling, via the control device, the actuation of the drive device when the first electrical charge is greater than the defined first threshold value and/or the second electrical charge is greater than the defined second threshold value. A machine tool for carrying out a method of this kind is also described.
