10.2.5 ADJUST SPRING FORCE
Like any technical component, springs are subject to natural wear. Thus, the spring force may
decrease after longer operation and must be readjusted.
Adjust the spring force so that the spring arm with end unit remains in any desired position.
CAUTION: DESTRUCTION OF THE SPRING ARM
The spring force is adjusted in the upper end position.

CAUTION: DESTRUCTION OF THE SPRING ARM
Screwing in the adjusting screw too deeply will destroy the spring arm. Carefully
screw in the adjusting screw while repeatedly checking the braking force:
• If the spring arm lowers - the spring force is too low:
The adjusting screw must be turned to the left (counterclockwise).
• If the spring arm rises - the spring force is too high:
The adjusting screw must be turned to the right (clockwise).
Use the same procedure for the ceiling and wall mount!
