To ensure the arm has the right spring pressure, install the wiper arm in such a way
that the shaft makes a 90° angle with the window (figure left) ánd that the shaft
makes a 90° angle with the wiper arm (figure right). If this is not the case, please
install spacer(s) to make the 90° angles.

area.
10. If the wipe arc is correct, adjust the position and the length of the arm if
necessary. Tighten the nuts properly now.
