1. A method for operating a mobile machine tool for machining a workpiece, wherein the machine tool comprises a guide element having a guide surface for relatively guiding the machine tool and a workpiece surface of the workpiece towards one another along a machining path, wherein the machine tool comprises a drive unit having a drive motor for driving a tool receptacle arranged on the drive unit for receiving a work tool, wherein the machine tool comprises a detection device for detecting at least one workpiece reference which is assigned, with respect to a machining path, to a machining start point where the work tool is intended to start the machining of the workpiece or to a machining end point where the work tool is intended to end the machining of the workpiece, wherein the tool receptacle is designed for rotationally driving the work tool about an axis of rotation and for adjusting the penetration depth of the work tool into the workpiece by means of a depth adjustment device of the machine tool between depth adjustment positions, wherein the work tool has, on a radially outer circumference of the work tool, a cutting region for cutting into the workpiece, thereby forming a machining edge which is at different distances from the at least one workpiece reference depending on at least two depth adjusting positions in which the work tool projects at different distances from the guide surface wherein the method comprises determining a distance value of a distance of the machining edge from the at least one workpiece reference and determining a predetermined depth value for the depth adjustment position depending on the distance value.
