4. Maintenance
Maintenance and inspection of the light should be done every two years.
In order to keep the system easy-running throughout its life span, we recommend that the hinges should be
greased once a year with acid-free grease.
Maintenance and safety check duties:
- Visual inspection
- Complete check of the ceiling or wall attachment
- Changing the halogen bulbs, if necessary
- Protective conductor resistance measurement
- Leakage current measurement
- Insulation resistance measurement, if necessary
- Functional testing
- Electrical safety check
- Light intensity measurement
- Completing the test report

attachment and new-type stand
♦
Adjusting the spring arm
(new-type attachment)
To adjust the spring force proceed as follows:
a) The spring arm moves down on its own:
•
Pull the lamp head approx. 20° downwards until
drilled hole B lies on the upper side of the joint
between spring arm and horizontal arm and a
screw is visible in the hole.
•
Insert a slotted screw driver into drilled hole B.
•
Turn adjusting screw to the left (anticlockwise),
the spring force increases.
b) The spring arm moves up on its own:
•
Pull the lamp head approx. 20° downwards until
drilled hole B lies on the upper side of the joint
between spring arm and horizontal arm and a
screw is visible in the hole.
•
Insert a slotted screw driver into drilled hole B.
Turn adjusting screw to the right (clockwise),
the spring force decreases.
