Abstract
The invention relates to a method for operating a hand-held machine tool with a tangential impact mechanism which can be driven by means of a drive shaft and an electric motor, according to which method an actual torque provided by the drive shaft is adjusted to a required torque depending on a measured motor current, wherein the required torque is less than a triggering torque of the tangential impact mechanism.
