7 Maintenance, cleaning and care
Attention:
Always remove the mains plug or disconnect the device from the control unit for all
maintenance, cleaning and repair work. Switch off the control unit beforehand!
Have repair work performed only by qualified specialists, or if in doubt, send in the
device to the following address:
XENOX Central Service
D-54518 Niersbach/Eifel, Germany
We will help you quickly without complications, and repair your defective device
within 24 hours!
For a long service life, you should clean your control unit after every use with a soft
cloth or soft brush. Mild soap or other suitable cleansers may be used as well. Make
sure that no fluid penetrates the interior of the device!
The external surface of the handpiece can be cleaned using a soft, possibly moist,
cloth. Mild soap or other suitable cleanser (e.g. isopropanol) may also be used. Do
not use solvents, as these could attack the plastic housing casings.
Make sure that no cleansers penetrate the interior of the handpiece!
Caution when using compressed air for cleaning: The dirt or dust that penetrates
could damage the handpiece.
Please do not oil the handpiece! The oil could flush out the grease filling of the
installed ball bearings.
7.1 Replacing the carbon brushes
Because of wear, it will be necessary
to replace the carbon brushes of the
motor after a certain period of use. If
the motor of your handpiece no longer
works properly, we recommend first
checking the carbon brushes and
replacing them as necessary. Included
in the delivery of your handpiece is
one set (2 pieces) of carbon brushes,
but you can also purchase them from
our service department. You will also
find the address in the chapter
