Remark:
Check the fixing screw at the lower part of the stand once a year and, if necessary, ad-
just.
Check and grease the security segment once a year.
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.

5.2 Adjusting the spring force
Edition 04
• Take out screw (1) and remove cover (2)
(Fig.1). Move the spring arm to a position
where the crossdrilled nut (3) is visible
through one of the two slots (4) (Fig.2).
• Take the pin (5) from the accessories and
insert it into one of the holes on the circum-
ference of the nut such that it can be turned
into the desired direction (Fig.3).
If the spring arm drops:
The spring force is too low.
- The adjustment nut (3) must be rotated to
the right (clockwise – facing the rear joint)
(Fig.3).
If the spring arm rises:
The spring force is too high:
- The adjustment nut (3) must be rotated to
the left (counterclockwise - facing the rear joint)
(Fig.4).
