If you violate the following regulations, you may lose
your entitlement to benefits.
NOTICE Machine damage if you
violate these regulations
If you violate the following regulations, your machine
may get damaged and/ or cause damage in the
surrounding area(s).
Thoroughly follow all instructions and information in
this section.
3.0.1 Intended use
The machine and the manufacturing software have
been designed for the commercial processing of
approved dental materials by specially trained persons.
The processed objects require additional work before
their use on patients.
Only process materials that you can select in the
manufacturing software.
Only use the machine and manufacturing software in
a commercial environment.
Before creating jobs, verify if the objects being pre-
pared may be utilized at the place of use according
to local and/ or national regulations or other author-
ized organizations or entities (e.g. professional asso-
ciations, health authorities). In particular, verify if the
material is approved for the machined object type
and if the object type is designed in accordance with
applicable regulations. Neither the manufacturing
software nor the machine will inform you about pos-
sible regulatory infringements, but will execute jobs
in accordance with the preferences and materials set
by the user.
Verify that each object type and each material in
your jobs are authorized manufacturing materials. If
mandated by local or national regulations, obtain rel-
evant authorization from the responsible organ-
izations or entities (e.g. professional associations,
health authorities).
Only import objects into the manufacturing software
which correspond to the object types that you can
select in the manufacturing software. While you can
import/ manufacture any other objects as well,
neither the manufacturing software nor the machine
are designed for these other objects and should not
be used in this way.
Do not manufacture implants or parts of objects that
are designed to have contact with implants. These
parts include parts of two-part abutments which
contain the connection geometry for the implant.
Do not manipulate the connection geometry of pre-
fabricated abutments (“prefab abutments”) and you
must always check finished objects for accurate con-
nection geometries (i.e. that connection geometries
of finished jobs have not been damaged).
3.0.2 Controlling the machine through soft-
w are
You control the machine through specially designed
applications which are supplied with the machine.

Colors of the working chamber lighting
If the working chamber lighting is insufficient,
provide additional lighting.
The machine illuminates the working chamber in
different colors. The color will change depending on
the state of the machine. You will find the colors and
respective machine status in the following table:
Color Status
White The machine is ready for operation.
You can open the working chamber door.
Blue The machine is operating.
The working chamber door is locked.
Red A machine malfunction has occured.
The working chamber door is locked.
4.6 CAM computer
To operate the machine, you must use a computer
running Windows®(“CAM computer”) and specially
designed software (“manufacturing software”). The
manufacturing software consists of the following
components:
nDENTALCAM ‒A CAM application for creating
and calculating virtual blanks (“jobs”).
nDENTALCNC ‒A CNC application for machining
jobs and maintaining the machine.
To create and design the dental objects you also need
a CAD application (sold separately by specialist
dealers).
4.7 Anti-soiling concept
The anti-soling concept decreases the soiling and wear
of sensitive machine parts.
The anti-soiling concept does not replace the regular
cleaning of the machine. Without regular cleaning, the
machine life decreases significantly.
NOTICE Machine damage when dry
machining without an air
extraction system
When dry machining, an operational external air extrac-
tion system must be installed. Otherwise, the machine
will get soiled over time and become defective.
Always use a correctly installed and operational
external air extraction system during dry machining.
The anti-soiling concept consists of:
Dry machining
nThe external air extraction system ‒An
external suction unit creates a vacuum in the work-
ing chamber and extracts machining debris from
it.
nAir that is emitted into the working cham-
ber ‒Blows machining debris away from the
spindle and other machine parts.
nThe internal vacuum sensor ‒Constantly
monitors the vacuum in the working chamber.
nThe ionizer ‒The ionizer electrically discharges
machining debris of certain materials to reduce
their distribution in the working chamber.
Wet machining
The cooling liquid keeps machining debris away from
sensitive machine parts.

5.4 Installing the pneumatics
WARNING Risk of injuries through
leaking compressed air and
lashing pneumatic hoses
Open or loose pneumatic connections can cause
severe injuries.
Ensure that during installation and maintenance
of the pneumatic hoses and of the compressed air
regulator compressed air is not conducted through
the hoses and connections.
Before conducting compressed air through the
hoses and connectors, verify that the hoses are
securely inserted into the correct connectors and
that they are not damaged. This also applies to the
compressed air regulator.
Do not conduct compressed air through damaged
hoses and connectors.
NOTICE The spindle may suffer
bearing damage and electrical
damage if the compressed air is contaminated
The incoming compressed air must be dry and oil-free
according to ISO 8573-1:2010 because the
compressed air regulator only serves as an indicator
for contaminated air.
Air purity according to ISO 8573-1:2010
Solid
particles
class 3 Filtration degree better than 5µm
for solid particles
Water
content
class 4 Maximum pressure dew point
+3°C
Residual oil
content
class 3 Maximum oil content: 1 mg/m3
Ensure that the compressed air meets the above
requirements.
Only connect the machine to the compressed air
supply if the compressed air regulator is properly
installed.
The machine requires the compressed air for the
following tasks:
nFor the opening and closing of the collet chuck
during tool changes.
nFor the spindle sealing air which prevents foreign
bodies from entering the spindle.
nFor the sealing air in the working chamber that
keeps machining debris away from sensitive
machine parts.
nFor the ionizer.
5.4.1 Overview compressed air regulator
The machine is connected to the external air supply via
a compressed air regulator. You can use this regulator
to monitor and regulate the pressure of the incoming
air.
The compressed air regulator is pre-installed in the
multi-purpose compartment. Location: Fig. 11 see
below
The regulator has the following connections:
n1/8” internal thread, fitted with male compressed
air connector to connect the external compressed
air supply
n6 mm push-in fitting to connect the machine.
You need to remove the tank before you can access
the compressed air regulator (Exchanging the cooling
liquid and cleaning the tank – on page33).
