Mobile hand-held machine saw with a pivoting scoring assembly

A mobile handheld machine saw having a saw assembly, which has a saw toolholder for a saw tool, and a saw drive motor for driving the saw toolholder, and having a guide device, which has a guide body having a guide surface extending along a longitudinal axis for guiding the handheld machine saw along a working direction on a workpiece or a guide rail and, on its upper side opposite to the guide surface, the saw toolholder as a whole is movably mounted by means of a saw depth setting bearing between an upper depth setting position and at least one lower depth setting position, in which the saw toolholder is adjusted closer to the guide surface than in the upper depth setting position, so that the saw tool, to introduce a saw cut into the workpiece, protrudes farther from the guide surface in the lower depth setting position than in the upper depth setting position;

• wherein the hand-held machine saw further comprises a scoring assembly, arranged in front of the saw assembly on the guide device with respect to the working direction, having a scorer toolholder for a scoring tool, and having a scorer drive for driving the scorer toolholder, which is movably mounted on or with respect to the guide device by means of a scorer depth setting bearing, which is separate from the saw depth setting bearing, between at least one active position, in which the scoring tool arranged on the scorer toolholder protrudes from the guide surface to introduce a score, which is upstream in the working direction from a saw cut to be introduced, into the workpiece, and an inactive position, in which the scoring tool is adjusted behind the guide surface;
• wherein the handheld machine saw, further comprising a driving device to provide a driving coupling between the saw toolholder and the scorer toolholder, by which, upon a movement of the saw toolholder between depth setting position, the scorer toolholder is carried along between the inactive position and the at least one active position, wherein the driving device has an actuation generator arranged on the saw assembly for actuating an actuation acceptor arranged on the scoring assembly.
