Mach M3
Dear customer!
Congratulations for achieving our new OT-lamp MACH M3.
The MachVISION optical system provides an illuminated field with improved contrast and
excellent homogeneity. Combined with the Duo-Focus feature this offers a unique possibility
for adaptation to the wound area.
With this lighting system you profit from a whole range of new developments, based on 50
years of experience in the production of operating and doctor’s lights.
The lighting system is characterised by a previously inconceivable general colour rendition
value of Ra = 96. In other words, the colours are reproduced naturally and in high
contrast. The wound area is shown in a comfortable light.
The different reds of a wound area can now be recognised very precisely. For the doctor or
surgeon this means a considerable improvement in the recognition of details in the wound
area.
The R96 lighting system uses computer-optimised cold-light filters that reduce both the
unwanted build-up of heat in the head area and the heat radiated on the illuminated
wound area to a minimum.
Pay attention to the special mounting instructions for ceiling and wall lamps.
All information quoted here relates only to the illuminants. Details of ceiling or wall installation
can be found in the mounting instructions.

3. Cleaning
V
1
Cleaning / disinfection and sterilisation
Basics
Efficient cleaning / disinfection is an essential requirement for effective sterilisation of the handle.
Within the scope of responsibility for the sterility of the products it should be noted that only sufficiently
validated equipment and product specific processes are used for cleaning / disinfection and that the
validated parameters are complied with in every cycle.
In addition, the hospital / clinic hygiene regulations must be observed.
Cleaning / disinfection
Cleaning and disinfection must be carried out immediately after use.
A mechanised process (disinfector) should be used for cleaning / disinfection. The efficiency of the
process used must be recognised and validated in principle (e.g. listed under disinfectants and
disinfection procedures tested and recognised by Robert-Koch-Institute / DGHM).
When using other procedures (e.g. a manual procedure), proof and process efficiency in principle must
be provided within the scope of validation.
Proof in principle of the suitability of the handles for efficient cleaning / disinfection was provided using a
cyclic cleaning system (Netsch-Bellmed T-600-IUDT/AN, programme 2 for small parts; code B).
It is not allowed to use agents / disinfectants, which contain the following substances, as these may
cause changes in the material:
- High-concentration organic and inorganic acids
- Chlorinated hydrocarbons
- 2-ethoxyethanol
3.1 Sterilisable handle
At delivery the lamp is equipped with the handle
sleeve 1. The handle sleeve is removable and
sterilisable. Before using the first time and before
every use the handle sleeve must be cleaned,
disinfected and sterilised.
The handle sleeve must be removed for sterilisation:
• To remove press the lock V and pull off the
sterilisable handle sleeve 1 while keeping the
lock pressed.
• To attach, push on and slightly twist the handle
until the lock V engages securely.
Handles often become unsterile during an OP;
therefore always keep additional handles available
for exchange.

* When occupying the disinfection zone (washing zone 2), the re-rinse and draining times will depend on
the respective objects being washed therein!
≈ 5 minutes
Sterilisation
Only previously cleaned and disinfected handles may be sterilised.
The handles are placed in a suitable sterilisation pack (one-way sterilisation pack, e.g. foil / paper
sterilisation bags, single or double pack) in accordance with DIN EN 868 / ISO 11607 for steam
sterilisation and then sterilised.
Use only the sterilisation procedure listed below for sterilisation. Other sterilisation procedures (e.g.
ethylene oxide, formaldehyde and low-temperature plasma sterilisation) are not permissible.
Steam sterilisation procedure
Validated in accordance with DIN EN 554/ISO 11134
Maximum sterilisation temperature 134°C
Proof in principle of the handles’ suitability for effective sterilisation was provided using a fractional
vacuum process (Euroselectomat 666 by MMM Münchner Medizin Mechanik GmbH, sterilising
temperature 134°C, holding time 7 min.)
Inspection / durability
The handles should be inspected for damage and changed before re-use, if required.
The handles may be cleaned / disinfected, sterilised and re-used for a maximum of 1000 times. If the
handles are re-used more than 1000 times, then this will be the responsibility of the hospital / clinic.

3.2 Lamp housing, dispersing lens
and support system
The OT-lamp MACH M3 has a high-quality surface,
which can be cleaned with conventional cleaning
agents.
The lens system 2 is made of a high-quality plastic.
Pay attention to the following during cleaning:
- Never wipe over the lens system 2 with a dry
cloth (always clean with a wet cloth).
- Only use disinfectants with less than 20%
alcohol.
Wipe the lens system 2 after cleaning with an
antistatic, non-fluffy cloth.
4. Maintenance
MACH lamps are supplied with brakes on the suspension fixture and on the lamp housing. Adjust these
brakes as necessary after installation.
If the lamp is difficult to move or if it does not stay in position, the brake forces should be adjusted.
The lamps and suspension fixtures have been designed and built, so that regular maintenance intervals
are not necessary.
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.
When adjusting the brakes or the hinges at the ceiling attachment please consult the mounting
instructions “Ceiling attachment with heavy central axis” or “Ceiling / wall attachment”.

4.1 Adjustments at the lamp head
The fine adjustment for handling the lamps can be
carried out at points 2 and 3.
To adjust the brakes use a screw driver with
appropriate size.
If you cannot adjust the brakes at points 2 and 3
anymore as tight as necessary, you will have to
replace them.
Remark:
In order to adjust brake 2, the upper housing
part must be removed.

Dr. Mach
Lamps and Engineering
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.
The halogen bulbs have a service life of approx.
1200 hours. We recommend changing all halogen
bulbs in a lamp at the same time to keep
maintenance work to a minimum.
• Turn off the lamp.
• Remove the upper housing part of the lamp as
described in chapter 4.2.
ATTENTION: Parts of the housing and the
halogen bulb may be very hot immediately
after use.
• Loosen the red knurled screw 1 and remove the
lamp socket 2 without removing the electrical
connection 3.
• Remove the faulty halogen bulb 4 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

4.3.2 Changing the dispersing lens
The dispersing lens is made of a high-quality plastic.
In case the dispersing lens looses its optical
characteristics, this can reduce the luminous
intensity and the light quality, which can be provided.
It may be necessary to exchange the dispersing
lens.
To change the dispersion lens proceed as follows:
Always place the dispersing lens on a soft, nonscratching base to preserve its surface.
• Turn off the lamp.
• Remove the upper housing part of the lamp as
described in chapter 4.2.
ATTENTION: Parts of the housing may be
very hot immediately after use.
• Loosen the six screws 1 at the bottom housing
part 2 with a cross screw driver.
ATTENTION: Hold the dispersing lens 3 and
the retaining ring 4 while loosening the
screws 1, so the lens and the ring cannot fall
down.
• Remove the dispersing lens 3 and the retaining
ring 4 downwards.
• Replace the dispersing lens.
• Fix the dispersing lens and the retaining ring at
the bottom part of the lamp housing.
