5 How to maintain your XO 4
5.1 Preventive service
Like all products used every day XO 4 needs preventive service
checks to prevent emergency repairs and other unplanned
downtime.
Approximately 30 days before the next preventive service, a
message appears on the unit display when XO 4 is switched on.
In case the visit becomes overdue, a warning message will ap-
pear on the unit display as well.
When the preventive service has been performed, the XO
service provider will set the date for the next preventive service
(normally at 12 month intervals, in some cases less).
5.2 Amalgam separator
Access to the combi-separator is gained through the cover (1)
of XO 4.

Figure 27 Access to amalgam-separator
Every 6-9 months, the amalgam container must be replaced. A
warning signal activates when the container is 95% full.

Figure 28 Dürr CAS 1 COMBI-SEPARATOR.
When the warning signal sounds from the separator, press the
button ”40” (see user instruction for Dürr CAS 1) behind the
cover, and the warning signal stops.
If the warning signal does not stop when button ”40” is pressed,
the amalgam container is 100% full and must be replaced imme-
diately.
More elaborate instructions on the replacement of the container
are provided in the user manual for Dürr CAS 1 COMBI-SEPA-
RATOR.
Amalgam waste is considered hazardous to the en-
vironment and should therefore be disposed of safely and
in accordance with regulatory requirements. Remember to
use safety gloves.
5.3 Instrument hoses
Remove instrument hoses by turning the knob handles (1) coun-
ter clockwise and pulling out the plug.
