4. Maintenance
4.1 Adjusting the mobility
The lamp MACH M2 is supplied with brakes on the
suspension fixture and on the lamp housing. Adjust
these brakes, if necessary, after installation.
If it is difficult to move the lamp, or if it does not
keep its set position, the brake forces should be
adjusted.
Service and a check of the lamp should be made
every two years.
In order to keep the system easy-running through-
out its life span, we recommend that the hinges
should be greased avery two years with acid-free
grease.
Attention: Before dismounting the lamp, set the
height adjustment of the spring arm to horizon-
tal position (see mounting instructions “Ceiling
attachment – wall attchment”).
4.1.1 Adjustments at the lamp head
Adjusting the mobility in the
lamp joint
6
is not
necessary.
In case the mobility in the
lamp joint 7
is too easy-
going or too heavy-going, the
brake screw 8
must
be adjusted with an appropriate screw driver.

4.2 Changing of spare parts
4.2.1 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. 1200 hours.
•
Turn off the lamp.
ATTENTION: Parts of the housing and the ha-
logen bulb may be very hot immediately after
use.
•
Turn the lamp, so the light outlet points to the
ceiling.
•
Turn the
screw 9
anticlockwise with an appro-
priate screw driver.
Remark:
In case there is no screw driver available, you
can use a coin.
