Method for controlling a wall-saw system comprising a guide rail and comprising a wall saw with a saw head, with a motorized feed unit which displaces the saw head parallel to a feed direction along the guide rail, with at least one saw blade which is fastened to a saw arm, pivotable about a pivot axis, of the saw head and is driven about an axis of rotation, and with at least one releasable blade guard, surrounding the saw blade, when producing a separating cut of end depth in a workpiece of workpiece thickness (d) between a first end point (E 1) and a second end point (E 2), comprising: ▪ before the start of a machining of the separating cut that is controlled by a control unit of the wall saw, at least the saw-blade diameter of the at least one saw blade, the positions of the first and second end points (E 1, E 2) in the feed direction, the end depth of the separating cut and a main-cut sequence of main cuts are determined, wherein the main-cut sequence comprises at least a first main cut with a first main-cut angle (α 1) of the saw arm and a first diameter (D 1) of the saw blade used during the first main cut and a following second main cut with a second main-cut angle (α 2) of the saw arm and a second diameter (D 2) of the saw blade used during the second main cut, ▪ during the machining controlled by the control unit - the saw arm is arranged at the negative first main-cut angle (-α 1) in a negative direction of rotation, and - the saw head is moved in a positive feed direction in the direction of the second end point (E 2) during the first main cut, wherein the saw arm arranged at the negative first main-cut angle (-α 1) is in a pulling arrangement, characterized in that, before the start of the machining controlled by the control unit, in addition a saw-arm length (δ) of the saw arm, which is defined as a distance between the pivot axis of the saw arm and the axis of rotation of the saw blade, a distance (Δ) between the pivot axis and the top side of the workpiece, a first width (B 1) for a blade guard used during the first main cut and a second width (B 2) for a blade guard used during the second main cut are determined, wherein the first and second widths (B 1, B 2) are each made up of a first distance (B 1a, B 2a) of the axis of rotation from the first blade-guard edge and a second distance (B 1b, B 2b) of the axis of rotation from the second blade-guard edge, and the saw head is stopped during the machining controlled by the control unit in a position in which a pivoting movement of the saw arm into the negative second main-cut angle (-α 2) takes place, wherein, after the pivoting movement of the saw arm into the negative second main-cut angle (-α 2), a second boundary (59, 62, 72), facing towards the second end point (E 2), of the wall saw coincides with the second end point (E 2), wherein the second boundary (59, 62, 72) of the wall saw is formed by a second upper exit point, facing towards the second end point (E 2), of the used saw blade at a top side of the workpiece if the second end point (E 2) constitutes a free end point without an obstacle, by a second saw-blade edge, facing towards the second end point (E 2), of the used saw blade if the second end point (E 2) constitutes an obstacle and the machining takes place without a blade guard, and by a second blade-guard edge, facing towards the second end point (E 2), of the used blade guard if the second end point (E 2) constitutes an obstacle and the machining takes place with a blade guard. ▪ before the start of a machining of the separating cut that is controlled by a control unit of the wall saw, at least the saw-blade diameter of the at least one saw blade, the positions of the first and second end points (E 1, E 2) in the feed direction, the end depth of the separating cut and a main-cut sequence of main cuts are determined, wherein the main-cut sequence comprises at least a first main cut with a first main-cut angle (α 1) of the saw arm and a first diameter (D 1) of the saw blade used during the first main cut and a following second main cut with a second main-cut angle (α 2) of the saw arm and a second diameter (D 2) of the saw blade used during the second main cut, ▪ during the machining controlled by the control unit - the saw arm is arranged at the negative first main-cut angle (-α 1) in a negative direction of rotation, and - the saw head is moved in a positive feed direction in the direction of the second end point (E 2) during the first main cut, wherein the saw arm arranged at the negative first main-cut angle (-α 1) is in a pulling arrangement, - the saw arm is arranged at the negative first main-cut angle (-α 1) in a negative direction of rotation, and - the saw head is moved in a positive feed direction in the direction of the second end point (E 2) during the first main cut, wherein the saw arm arranged at the negative first main-cut angle (-α 1) is in a pulling arrangement,
