Method for controlling a wall saw system comprising a guide rail and a wall saw having a saw head, a motorized feed unit which displaces the saw head parallel to a feed direction along the guide rail, a first saw blade (16.1) and a larger, second saw blade (16.2) when creating 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), wherein the first or second saw blade (16.1, 16.2) is fastened to a saw arm of the saw head and is driven about an axis of rotation, the saw arm being pivotable about a pivot axis, 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 first saw blade diameter (D.1) of the first saw blade (16.1), the second saw blade diameter (D.2) of the second saw blade (16.2), the positions of the first and second end point (E 1, E 2) in the feed direction, the end depth of the separating cut and a main-cut sequence of m main cuts, m ≥ 2, 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 with the first saw blade (16.1) is arranged in a positive direction of rotation at the positive first main-cut angle (+α 1) or in a negative direction of rotation directed opposite to the positive direction of rotation at the negative first main-cut angle (-α 1), and - the saw head is moved in a positive feed direction in the direction of the second end point (E 2), wherein, after the machining of the separating cut with the first saw blade (16.1), the controlled machining of the separating cut is interrupted by the control unit and the wall saw is moved by the control unit into a park position, 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 first or second saw blade (16.1, 16.2), and a distance (Δ) between the pivot axis and an upper side of the workpiece are determined. ▪ before the start of a machining of the separating cut that is controlled by a control unit of the wall saw, at least the first saw blade diameter (D.1) of the first saw blade (16.1), the second saw blade diameter (D.2) of the second saw blade (16.2), the positions of the first and second end point (E 1, E 2) in the feed direction, the end depth of the separating cut and a main-cut sequence of m main cuts, m ≥ 2, 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 with the first saw blade (16.1) is arranged in a positive direction of rotation at the positive first main-cut angle (+α 1) or in a negative direction of rotation directed opposite to the positive direction of rotation at the negative first main-cut angle (-α 1), and - the saw head is moved in a positive feed direction in the direction of the second end point (E 2), - the saw arm with the first saw blade (16.1) is arranged in a positive direction of rotation at the positive first main-cut angle (+α 1) or in a negative direction of rotation directed opposite to the positive direction of rotation at the negative first main-cut angle (-α 1), and - the saw head is moved in a positive feed direction in the direction of the second end point (E 2),
