Adjustment possibilities for arms
10.1
Angle adjustment
The serration of the level adaptor allows a step-by-step adjustment of the angle
(6°).
CAUTION: The connecting screw
between the operator and the lever
arm must be tightened firmly, and
must be checked constantly.
It is recommended to tighten the connecting screw after the final adjustment.
9.2 Length adjustment
The length of the standard arms can be adjusted in a certain range for optimal fit
to the lintel depth. The two marked screws thereby have to be loosened with a
5 mm Allen key. The profile must be relocated to set the lever to an angle of about
90° to the door leaf.
CAUTION: All screwed connections must be firmly tightened!
To lower the initial load, the lever arm can be adjusted at an angle of 6° in the
counter rotation sense of the opening.
