A motor-driven saber saw includes a guide device releasably connectable with the saw housing () in a region of the neck () and including a guide element () for guiding the saber saw () over a workpiece, a connection device () for connecting the guide element () to the housing () and having at least one connection part extending along an axis (A) and connectable with the neck (), with the guide element () being supported on the at least one connection part () for displacement along the axis (A), and with the guide device () further including at least one spring element () located between the at least one connection part () and the guide element ().

Motor-driven saber saw with guide device

An automatic balancing device for a rotatable system includes a track (18) arranged about a rotational axis (H) of the rotatable system and having two surfaces (22, 22) inclined toward each other in a direction of a centrifugal force acting (F) acting on at least one balancing body (20) which is received in a cross-section formed by the two inclined surfaces (22, 22) and limited by an elastic locking element (24) arranged therebetween for displacing the at least one balancing body (20) away from the inclined surfaces (22, 22) in a direction opposite the direction of the centrifugal force (F) and for pressing the at least one balancing body (20) against an inner boundary of the track (18) for locking the balancing body (20) when a rotational speed of the system is below a predetermined threshold.
