On axis A4 there is an orientation indicator consisting of the indicator an-
gle and the indicator pin.
If the mastering is lost, it is necessary to determine which side of the an-
gle the pin is on before addressing the premastering notch. The counter-
clockwise direction of rotation corresponds to minus and the clockwise di-
rection to plus.

If the pin is located on the left in the minus range, the premastering notch
must be addressed in the plus direction.
The premastering notch is addressed in the minus direction if the pin is
