•
Remove all arm and joint covers so that the adjustment rod is visible (Fig. 1).
•
The adjustment rod must always be parallel with the arm. This can be checked by
measuring at two points as far away from each other as possible but with the same
diameter of the pull rod (Fig. 1). The parallelism must not deviate by more than
0.6 mm. The measurements must be performed with the arm in the uppermost and
lowermost positions. If not parallel, loosen the locking nuts and adjust by turning the pull
rod.
