Abstract

A motor unit has a tool for engaging a work piece with a frame unit, which has a gripping element for the handheld operation of the device, wherein a mechanical coupling is provided between the motor unit and frame unit, which encompasses at least one dampening element, in such a way that makes it possible to precisely guide the tool while improving the dampening of vibrations between the motor unit and frame unit. The frame unit has at least one abutting element, against which the motor unit abuts when a working force exerted by the work piece on the tool has a value below a minimum value.
