Abstract: A power tool with a drive motor and a drive belt guided about a drive pulley and an output pulley has a tool driven by the drive motor through the drive belt. A tensioning device is provided that changes a spacing between the drive pulley and the output pulley and has at least one tensioning position and at least one release position. In the at least one tensioning position, the drive pulley and the output pulley have a first spacing relative to one another and in the at least one release position have a second spacing to one another that is smaller than the first spacing. The drive belt is an elast belt and the tensioning device, as a result of inherent tension of the elast belt, is secured in the at least one tensioning position.

Abstract: A guide cart for a hand-held power tool with a driven tool has a pivot device that is pivotable between an open position and a fixation position. A fixation elements is provided that releasably secures the power tool on the guide cart. The fixation element is secured on the pivot device. The pivot device has at least one support for supporting a tool of the power tool in the fixation position of the pivot device. The guide cart has a holder for the power tool, wherein holder is provided with a base plate and has at least one lateral guide for the power tool. The pivot device is supported on the base plate. The pivot device and the baseplate together form a C-shaped frame.
