Abstract: The invention relates to a power tool (1), especially in the form of a hand-held jigsaw (2). In order to allow for a semi-autonomous operation which assists the user to guide the tool, the tool is provided with a sensor system (27) for observing a detection surface (31, 43) within which the desired working direction is detected as a path default (23) for the saw blade (8) serving as the tool (7) with respect to its alignment relative to the jigsaw (2), the detected path default being intended for downstream control means (26). Said control means align the saw blade (8) relative to the path default (23) by rotating it about its longitudinal axis (25) so that the user guiding the saw blade (2) only has to make sure that the path default (23) extends inside the detection surface (31, 43).

Abstract: A handheld machine tool has a drive motor and a supplementary handle which is mounted on the housing of the handheld machine tool and is assigned a drive-torque limitation device, the drive-torque limitation device limiting the drive torque to a torque level below a maximum torque if the supplementary handle is not mounted on the housing.

Abstract: The disclosure provides a transverse guide of a saw blade for a machine tool, particularly for a hand-guided machine tool in the form of a band saw or jigsaw, wherein the saw blade can be rotated about the longitudinal axis thereof by way of said guide in the opposite direction to said forces as a function of transverse and/or torsional forces acting on the saw blade.

Abstract: A hand-held jigsaw includes a saw blade and control element for automating a tracking the saw blade, the hand-held jigsaw, or both along layout lines. A sensor, preferably a camera unit, detects a layout line provided on a work piece.
