Abstract: A method for determining a remaining service life of a hand-held power tool includes, in an operating mode detection step, detecting an operating mode of the hand-held power tool by an alignment of operating data of the hand-held power tool with a comparative value table stored on the hand-held power tool and/or by a switch position detection function of an operating mode selection switch. In a computing step, the remaining service life of the hand-held power tool is calculated via at least the operating mode and its operating time and output to a user of the hand-held power tool in an outputting step.

Abstract: A suction adapter, in particular a suction drill suction adapter, for connecting an insertion tool, in particular a suction drill, to a suction apparatus includes at least one insertion tool receiving region, in which the insertion tool is arranged, at least one connection interface with respect to an insertion tool suction channel of the insertion tool, and at least one, in particular dimensionally stable, discharge guiding unit configured to delimit a suction channel. The at least one discharge guiding unit has at least one discharge guiding element configured to delimit a suction channel outlet of the suction channel and which has a longitudinal axis. The longitudinal axis of the at least one discharge guiding element is orientated parallel with a main extent axis of the at least one insertion tool receiving region in a region of the suction channel outlet in at least one operating state.

Abstract: A method for generating at least one identifier of at least one article, in particular a power tool, includes sensing at least one usage parameter and/or at least one article parameter of the article with at least one sensing unit. The method further includes creating with at least one computing unit, in dependence on the at least one sensed usage parameter and/or the at least one sensed article parameter, a certificate of the article, and/or assigning the article to at least one person.
