Abstract

A method is for operating a hand-held power tool that includes an electric motor. The method includes determining a signal of an operating parameter of the electric motor; determining an application class at least partly on the basis of the signal of the operating parameter; and providing comparative information at least partly on the basis of the application class including (i) providing at least one model-signal form, and (ii) providing a threshold value for correspondence. The model-signal form can be assigned to an established state in the progress of the work performed by the hand-held power tool. The method further includes comparing the signal of the operating parameter with the model-signal form and determining a correspondence evaluation from the comparison. The correspondence evaluation is at least partly based on the threshold value for correspondence.
