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.
