Springs are wearing parts, thus the spring force can decrease in time and must be readjusted.
Note: Set the spring force in such a way, that the spring arm with the lamp head holds its position
at every set height.
•
Dismount the lamp head in reverse order of mounting (see chapter 5.2).
•
Check the thickness of the segment. It must be at least 1,5mm. In case the thickness of the segment
is less than 1,5mm, it has to be changed.
•
Grease the segment and the coupling journal of the lamp.
•
Mount the lamp to the spring arm (see chapter 5.2).
