Controlled wall saw and method for controlling the wall saw

A method of controlling a controllable wall saw (1) that includes a guide rail (2) securable on a to-be-cut wall (7), a saw head (3) displaceable along the guide rail (2), a rotary drive, and a pivotally adjustable saw arm (4) on a radially end of which a rotatably driven, disc-shaped saw blade is releasably mountable, the method comprising the steps of effecting, in a manual preparation process, fixation of the guide rail (2) on a to-be-cut wall (7), positioning of the saw blade (5) in an initial position, and inputting, over the input means (14), at least a saw blade diameter (d), two inflexion points (W), and calculating, based on input data, a rotational speed, a displacement speed, and an incremental cut depth (S);

• and effecting, in a later sawing process which is completely program-controlled by programmable control means (13), in a first step, pivoting the saw arm (4) by the incremental cut depth (S) in a direction of the to-be-cut wall (7), in a second step, displacing the saw head (3) along the guide rail (2) with the displacement speed in a first direction toward first inflexion point (W), and in a third step, displacing the saw head (3) along the guide rail (2) in a second direction opposite the first direction and toward the second inflexion point (W);
• and thereafter, running at least one time a step sequence encompassing at least the first step, the second step, and the third step.
