Sterilisation
Only previously cleaned and disinfected handles may be sterilised. The
handles are placed in and sterilised in suitable sterilisation packaging
(single-use sterilisation packaging, such as wrap / paper sterilisation
bags, single or double pack) in accordance with DIN EN 868 / ISO
11607 for steam sterilisation. Only the sterilisation procedure listed
below may be used. Other sterilisation procedures (such as 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
The principle proof of the suitability of the handles for effective steri-
lisation was carried out using a fractional vacuum process (Euroselec-
tomat 666 by MMM Münchner Medizin Mechanik GmbH, sterilising
temperature 134°C, holding time 7 min.). If other procedures (such
as manual cleaning) are used, proof of the suitability and principle
effectiveness of the procedure must be given as part of the validation.
Inspection/durability
Each time before they are reused, the handles should be inspected for
damage and replaced if necessary.
The sterilisable handle sleeve must be discarded and replaced with a
new one after 1000 sterilisation cycles or after a maximum of 2 years.
A stamped number on the inside of the handle sleeve (as shown) can
be used to check the year of manufacture of the sleeve (in the picture,
12 stands for the year 2012).

4.2 Light body, protective screen and support system

The surface of the light is made of a high-quality material that can be
cleaned with conventional cleaning agents.
The protective screen 9 is made of a high-quality plastic. Pay attention
to the following during cleaning:
• Always clean the screen 9 with a wet cloth (never clean with a dry
cloth!).
• The protective screen 9 is to be wiped with an anti-static agent us-
ing a lint-free cloth.

5. FIRST USE AND MAINTENANCE

The KaWe examination light is to be serviced at least every two years.
This includes an electrical and mechanical inspection.
Please heed the user's manual and assembly instructions for
the support systems as these may contain different mainte-
nance timeframes.
Caution: Make sure that the height stop (if present) is hori-
zontal before the lamp is removed from the spring-loaded
arm. Please heed the user's manual and assembly instruc-
tions for the support system.
Note: Before conducting any maintenance or tests on
the KaWe examination light, unplug it from the electrical
outlet and ensure that it will not be plugged in again until
the work has been completed.

5.1 Procedure for first use and maintenance of the light

Inspect the KaWe examination light (especially for the following):
• Paint defects
• Cracks in plastic parts
• Deformation of the support system
• Loose parts
• Check the connection between the examination lamp and support
system.
• Inspect and grease the mechanism securing the arm to the stand
• Proper operation
• Electrical safety
Note: Circuit diagrams, part lists and maintenance instruc-
tions are available upon request. The replacement of parts
and repair work on the lamp during treatment are not al-
lowed. Touching parts contained within the lamp housing
while at the same time touching a patient is not allowed.

6.3 Electrical installation information

The KaWe examination light is exposed to a current peak when it is
0 %
switched on and is therefore equipped with a power adapter. The
adapter has a wide range input, an input voltage of 100 - 240V AC, 50
- 60Hz, and output voltage of 24V DC. If a changeover relay is required
for an existing on-site emergency power supply for the KaWe adapter,
this relay must be ordered separately from KaWe.
Warning! This light is a Protection Class I device. To avoid
0 %
the risk of electric shock, this unit must be connected to a
grounded electric outlet.
