Abstract: A method for operating a hand-held power tool, in particular a rotary impact wrench, the hand-held power tool comprising a tool holder for receiving a tool such as a tool bit or a nut, wherein the tool is configured to rotatably drive the fastening element via a corresponding drive of a fastening element, includes screwing the fastening element into a substrate while rotating the tool holder, and thus the fastening element, in a first direction of rotation, and rotating the tool holder in a second direction of rotation opposite the first direction of rotation at a predefined speed and for a predefined time period.

Abstract: A method for operating a hand-held power tool is disclosed, with the hand-held power tool including an electric motor. The method includes step (S1) providing comparative information, having the steps of (S1a) providing at least one model signal waveform, said model signal waveform being assignable to the work progress of the hand-held power tool, and (S1b) providing a threshold of a match. The method further includes step (S2) ascertaining a signal of an operational variable of the electric motor. The method also includes step (S3) analyzing the comparative information and the signal of an operational variable, having the steps of (S3a) comparing the signal of the operational variable with the model signal waveform and ascertaining a match signal from the comparison, and (S3b) ascertaining a match evaluation, said match evaluation being carried out at least partly using the threshold of the match and using the match signal. In addition, the method includes step (S4) detecting the work progress at least partly using the match evaluation ascertained in step S3, said comparative information being provided at least partly on the basis of an automatic evaluation of the match signal. An associated hand-held power tool is also disclosed.

Abstract: A method for operating a hand-held power tool, preferably a rotary impact wrench, the hand-held power tool comprising a tool holder for receiving a tool such as a tool bit or a nut, wherein the tool is configured to rotatably drive the fastener via a corresponding drive of a fastener includes partially releasing the fastener from a screwed state, by rotating the tool holder and thus the fastener in a first direction of rotation, rotating the tool holder in a second direction or rotation opposite the first direction of rotation, and renewed rotating of the tool holder and thus the fastener in the first direction of rotation.
