4.4.1 Changing the halogen bulbs
Dr. Mach uses special halogen bulbs as illuminants.
Only original Dr. Mach replacement bulbs may be used.
The use of other bulbs can lead to a considerable reduction of the light power and increase in the thermal
load.
The halogen bulbs have a service life of approx. 1000 hours. We recommend changing all halogen bulbs
in a lamp at the same time to keep maintenance work to a minimum.
To replace the halogen bulbs proceed as follows:
•
Turn off the lamp.
•
Loosen the housing cap by pushing the arrest pin
2
(e.g. with a ball-pen).
•
Turn the cover
1
slightly.
•
Remove cover
1
.
ATTENTION: Parts of the housing and the
halogen bulb may be very hot immediately af-
ter use.
•
Loosen the red knurled screw
3
and remove the
lamp socket
4
without removing the electrical
connection
5
.
•
Remove the faulty halogen bulb
6
from the
socket.
ATTENTION: Never touch new halogen bulbs
with your fingers. Always use the original
packaging or a clean cloth.
•
Carefully insert the new halogen bulb
(22.8V/50W).
•
Re-assemble the lamp in reverse order
ATTENTION: When mounting the cover 1, the
arrest pin 2 must snap in audible.
