1. Safety instructions
Please pay attention to the directions for use when handling the lamp.
Attention:
This device is not suitable for use in hazardous locations. The lamp is classified
As a Group 1 device according to the MedGV (Medical Ordinance).
Repairs to the lamp and special installation work on the reflector or plug-in socket should
only be carried out by ourselves or a company expressly authorised by ourselves.
The manufacturer is only responsible for the safety of the lamp if repairs and alterations have
been carried out by themselves or a company who can guarantee that the safety regulations
have been observed.
The manufacturer is not liable for personal or material damages if the lamp is misappropri-
ately or incorrectly operated or misused.
The lamp body may only be dismantled from the swivel arm in reverse order of its assembly.
Make sure that the lamp is in perfect working order before every use.

2. Operating the lamp Mach 120F/120
There are two types of Mach 120F/120 -lamps
available:
• Mach 120F with focusable light field and dielec-
tric light system Ra=93
• Mach 120 with fix-focus and standard light sys-
tem Ra=86
The lamp types are equipped with an external
transformer:
• Mach 120F/120, voltage 22,8V / external trans-
former.
2.1 ON/OFF switch
The switch 37 with signal lamp at the lamp bow
turns the lamp on and off.
Because of the external transformer of the lamps,
in addition to the switch 37 a two-pole switch
ON/OFF must be provided by the customer.
2.2 Positioning
Use the handle 17/50 or the handle rail GL to posi-
tion the lamp.
There are two handle types available:
• Handle 17
The handle 17 is fixed to the handle bar 16 and
can be removed.
• Sterilizable handle 50
The sterilizable handle can be removed for ster-
ilisation. It is fixed by the couple to the handle
bar 16.
2.3 Light field adjustment
- focusing (Mach120F only)
The lamp models Mach 120F have a focusing func-
tion. That means, you can either enlarge the di-
ameter of the light field or bundle the light to a
smaller area, depending on the circumstances.
To activate the focusing function, move lever 08 at
the lamp head up and down (see figure).

3. Cleaning
3.1 Sterilisable handle
The lamps Mach 120F/120 can be equipped as an
option with a sterilisable handle 50.
The sterilisable handle 50 can be removed and
sterilised at temperatures up to a max. of 134°C.
No other parts may touch the handle during sterili-
sation. The handle should be placed in a vertical
position during sterilisation.
3.2 Lamp head, protective disk
The lamp has a high-quality surface, which can be
cleaned with conventional cleaning agents.
The protective disk 15 is made of an high-quality
plastic. Pay attention to the following during clean-
ing:
- Wipe over the disk 15 with a wet cloth (never
use a dry cloth!).
- Only use disinfectant with less then 20% alcohol.
Wipe the disk 15 after cleaning with an antistatic,
non-fluffy cloth.

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
4.1 Adjustments at the ceiling/wall
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.
4.2 Adjustments at the lamp head
♦ Manipulating the lamp
The lamp bow 32 enables a perfect movability and
positioning of the lamps Mach 120F/120.
The brake force in the axis Ais set. It is usually not
necessary to adjust it.

4.3 Changing of spare parts
4.3.1 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.
To change the bulbs proceed as follows:
• Attention!! Turn off the lamp!
• Loosen three screws 27 at the base frame 01.
• Remove housing lower part 02 by pulling it
downwards.
Attention! If the bulb is changed immediately
after operating the lamp, some parts of the lamp
may be hot.
Do not touch the halogen bulb with naked
hands.
• Draw halogen bulb 11 (22,8-24V/50W) carefully
from its socket.
• Put in the new halogen bulb.
• Mount the housing lower part 02 in reverse order
of dismounting it.
Remark:
The halogen bulbs have a service life of approx.
1000 hours without any deterioration in their
luminosity.
4.3.2 Changing the fuses
Because of the external transformer of the Mach
120 lamps, the necessary fuses must be provided
by the customer.
Pay attention to the instructions from the local
installer.

4.3.3 Changing the filter disk
The filter disk between reflector and protective disk
(Mach 120F only) prevents a damaging heating of
the illuminated area.
ATTENTION!
The lamps may not be used without this filter.
To change the filter disk 55 proceed as follows:
• Attention!! Turn off the lamp!
• Remove housing lower part 02 as described at
point 4.3.1.
The filter disk 55 is held by the 4 springs (holders)
54.
• Press the filter disk 55 carefully against 2 springs
54a (I.) and lift it off the other 2 springs 54b (II.).
• Insert the new filter disk in reverse order.
Only use filter disks that have been cleaned
properly.
• Fix the housing lower part 02 as described at
point 4.3.1.

4.3.4 Changing the protective disk
In case you notice a impediment of the light quality
because of a dull protective disk, it may be neces-
sary to change the disk.
To change the disk proceed as follows:
• Attention!! Turn off the lamp!
• Remove housing lower part 02 as described at
point 4.3.1.
The protective disk 15 is held by the four springs
(holders) 13.
• Press the protective disk 15 against 2 springs 13a
( I. ) and lift it off the other two springs 13b ( II. ).
• Insert the new protective disk in reverse order.
Attention: Only use protective disks, that
have been cleaned properly.
• Fix the housing lower part 02 as described at
point 4.3.1.
