Basically, the following applies:
The adjusting screws have a right-hand
thread.
• Screwing in = turning clockwise reduces
the swivel angle.
• Screwing out = turning counterclock-
wise increases the swivel angle.
For safety reasons, the adjusting screws
may be screwed in or out by a maximum of
1-2 turns depending on the actuator size.
Turning in or out by 1 turn corresponds to
an angle adjustment of up to 5°.
The adjusting screws must only be screwed
out so far that the screw heads protrude
only a few millimeters beyond the lock nut
on the actuator housing.
When screwing in, make sure that the ad-
justing screws remain completely in the
thread of the lock nut on the actuator hous-
ing.
Observe the following tightening torques
when tightening the lock nuts:
