Adjusting the Engaging Width

    1
    Loosen both screws (1).
    2
    Push insert (2) into the desired position.
    A scale simplifies the adjustment.
    3
    Retighten both screws (1).
    4
    Repeat the setting process for the other side.

The entire engaging width consists of the value for the left (Ua) and the right (Ub) side.
Both values may be equal (symmetrical setting) or may differ.
