In an electrically operated manual labour device (1), the electric motor which actuates an axially displaceable impact element (32) is constructed as an AC oscillatory magnet (12) whose armature (15) acts, with a high impact sequence as a function of the mains frequency, on the impact element (32) equipped with a small mass. And said element is inserted, following the frequency of the armature (15), in a cylinder (31) held fixed in a housing (11) of the device (1), with which cylinder an attachment sheath (41) can be detachably coupled, which sheath receives a tappet (43) which is displaceable with respect to said sheath by means of the impact element (32) and acts on a component (2) which is to be driven or on a tool. By means of this design, it is made possible to make a nail driver or the like of extremely compact design since the cylinder (31) which is provided with the impact element (32) can be arranged directly next to the AC oscillatory magnet (12). In addition, the power losses are low since the armature (15) which oscillates about an axis acts directly on the low-mass impact body (32). Furthermore, attachment sheaths which are designed for different applications can be coupled to the cylinder (31). <IMAGE>
