Changing the suction motor

The motor of the suction device has a service life of approx. 1,200 hrs.
You will notice the motor is worn when suction does not start in either
automatic or manual mode. When this happens, have the motor replaced
by a trained service engineer.
6.3
Using the cleaning hose and the wet cleaning
process
The processing chambers of devices used for dry milling of zirconium
oxide should be cleaned regularly in order to prevent deposits of
zirconium oxide dust in the chamber. A second cleaning hose with a
nozzle can be used before the wet cleaning process in order to support
the user when sucking zirconium oxide dust out of the device's
processing chamber. This hose is available separately as a spare part
(REF 65 89 795). We recommend carrying out this cleaning procedure (or
the wet milling of a restoration) at least once per week if the device is used
for dry milling of zirconium oxide.
Proceed as follows to use the cleaning hose and to execute the
recommended wet cleaning process:
1. Remove the normal hose which is connected to the milling/grinding
unit.
