2 GENERAL SAFETY
INSTRUCTIONS
2.1 Intended use
The machine and the manufacturing software are
designed for the commercial processing of dental-tech-
nical objects. The finished objects require further
processing before they can be used with the patient.
The machine is designed for dry machining.
Process only materials that you can select from the
manufacturing software.
Only import objects into the manufacturing soft-
ware that correspond to the object types that you
can select in the manufacturing software. Although
you can import/manufacture any other objects,
neither the manufacturing software nor the
machine are designed for these other objects.
Do not manufacture implants or parts of objects
that touch implants. In the case of two-part abut-
ments, this includes the part which has the con-
nection geometry to the implant. Do not
manipulate the connection geometry of pre-
fabricated abutments and always check finished
objects for correct connection geometries (i.e. con-
nection geometries of finished jobs were not dam-
aged).
