The center of the calibration crown (tooling) should be
X = 2 – 3 mm
behind the center of the pendulum roller head.
Then you have to loose the two M10 screws on top of the tooling plate.
Then you loose the M6 counternut (1) below the plate and then you can adjust the position with the M6 screw (2). When you turn clockwise, you will reduce the distance, when you turn counterclockwise you increase the distance between the the calibration crown and the pendulum roller head.
