Abstract: The disclosure relates to a method for operating a hand-held power tool comprising at least one acceleration sensor, said hand-held power tool being monitored for any faults and the operating behavior thereof being influenced when a fault is sensed. The disclosed method involves the following steps: having the acceleration sensor sense vibrations of the hand-held power tool, comparing the sensed vibrations with previously stored reference vibrations, identifying a fault of the hand-held power tool when the sensed vibrations differ from the reference vibrations by a predefined measure.
