3 Operating regulations
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.
Intended use
The machine and the manufacturing software have
been designed for the commercial creation of dental
objects by specially trained persons. The 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 prepared may be utilized at the place of use according to local and/ or national regulations or other
authorized organizations or entities (e.g. professional associations, 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 possible 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
relevant authorization from the responsible organizations or entities (e.g. professional associations,
health authorities).
Only manufacture objects 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 prefabricated abutments (“prefab abutments”) and you must always check finished
objects for accurate connection geometries (i.e.
that connection geometries of finished jobs have
not been damaged).
Controlling the machine through software
You control the machine through specially designed
applications which are supplied with the machine.
Always use the latest program version that officially
supports your machine.
Before installing or operating the machine, read
the documentation forthe applications.
Ensure that your CAM computer meets all system
requirements.
Maintenance and cleaning
Maintenance and cleaning is part of standard machine
usage.
Clean and maintain the machine as required. Only
then can the machine reach a long service life.
Spindle
The spindle of your machine is a high-precision instrument.
Do not use unbalanced tools at high rotational
speeds. Such an imbalance puts a great strain on
the spindle’s ball bearings, which can cause the
bearings to be damaged.
When working in the working chamber, do not
apply manual pressure against the spindle.
Unattended operation
If the machine runs unattended, the risk of material
damage is increased.
Only allow unattended operation of the machine
to occur if the following conditions are met:
The national and local laws allow it.
n

8 Maintenance and do-
it-yourself
Some day-to-day basic maintenance and preventive
maintenance is essential to keep the machine mechanics and electric components in good condition for
proper machining results.
It is your responsibility to make sure that preventive
maintenance, as well as basic maintenance, is
performed.
You are the only one who can ensure that your
machine receives the proper maintenance care. You
are a vital link in the maintenance chain.
Basic maintenance
Basic maintenance includes tasks which are part of
everyday operation. You are responsible to ensure
that these tasks are carried out according to the maintenance table. You only need minimal manual skills for
these tasks and most required tools are provided with
the machine.
Maintenance section
For your convenience, the machine lists all basic maintenance tasks in the
screen. In the
the individual tasks are due.
When you have marked a maintenance task as
complete, its time interval is reset and the list is
updated accordingly.

Where to get service?
Customer service is your main contact for all service
related questions. They will provide you with spare
parts, maintenance tips and they will perform
preventive maintenance for you on request.
When your machine is delivered or installed, ask
the service technician for contact details for the
customer service team. We also recommend
scheduling the first preventive maintenance
appointment at this point to ensure your machine
gets proper maintenance.
Definition of wear parts
The machine and the extra equipment are warranted
for a period of 24 months or 2,000 operating hours,
whatever comes first. The warranty covers defects in
materials or fabrication as long as the regulations for
using the machine in all documents are followed.
Of course, the warranty also covers wear parts as long
as their failure cannot be attributed to the functionrelated abrasion. The wear parts that are mentioned in
the maintenance table can already wear down within
the warranty period due to their normal function. The
average useful life of the wear parts can be seen in the
maintenance table.
Use these values to determine operating costs, to plan
your spare part stock as well as to create individual
maintenance and service plans.

Preventive maintenance
Preventive maintenance for this machine has to be
scheduled every 2years, or after 1,000operating
hours at the latest.

Cleaning the housing
NOTICE
Damaging of the housing when using an
unsuitable cleaning agent
If you use an unsuitable cleaning agent and/or
cleaning tool for cleaning the machine housing, the
surface or the adhesive foil can get damaged.
To avoid scratches, only use a microfiber cloth to
clean the housing.
Take care of the adhesive symbols so that they do
not peel off. The adhesive foil is especially sensitive to rubbing and strong cleaning agents.
If the usage of a special cleaning agent is necessary
to eliminate certain dirt, we recommend checking
the suitability of the cleaning agent at a hidden
place of the part first.
1.
Clean the surface with a dry microfiber cloth.
2.
If some dirt cannot be removed this way, moisten
the cloth. Use a pH neutral cleaning agent if
necessary.

Calibrating the axes
NOTICE
Deterioration of machining results caused
by an incorrect calibration
At delivery, your machine is already calibrated. As
long as your machining results are accurate, a new
calibration is not necessary. A calibration takes much
time and will deteriorate the machining results if it is
improperly executed.
In case of inaccurate machining results, try adjusting the machining conditions first: Check the fixation and quality of the blank and the state of the
tool.
Before
