2 GENERAL SAFETY
INSTRUCTIONS
2.1 Intended use
The machine and the manufacturing software are
designed for the commercial machining of dental-tech-
nical objects. The processed objects require additional
work before their use on patients.
The machine is designed for wet and dry machining.
Machine only blanks and objects whose types you
can select in each case in the manufacturing soft-
ware. Although you can also machine any other
objects and blanks, neither the manufacturing soft-
ware nor the machine are designed for these other
blanks and objects.
Under certain circumstances, the use of this
machine may be subject to legal requirements.
Observe applicable local and national regulations
as well as the requirements of other authorized
organizations or agencies (e.g., professional asso-
ciations, health authorities) that have jurisdiction.
Obtain authorization from the appropriate organ-
ization (e.g., professional associations, health
authorities) as needed. For all materials machined
with this machine, observe the material’s instruc-
tions for use with respect to the intended use and
all related software and machining procedure
requirements.
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 and always
check finished objects for correct connection
geometries (i.e. connection geometries of finished
jobs were not damaged).

3. Remove the housing.
4. Carry out the necessary repair.
5. Install the housing.
6. Connect the machine to all lines.
7. Switch on the machine at the main power switch.
Only have qualified electricians work on any elec-
tric equipment.
Ensure that an operational Residual Current
Device/ Ground Fault Circuit Interrupter is
installed on the electric circuit of the machine.
Run electric cables so that they cannot be
damaged by sharp edges.

movement.
2.4.4 Working chamber
Danger of crushing due to moving machine parts in
the working chamber
Only use the machine when the working chamber
door is completely closed and undamaged during
machining.
Do not circumvent or deactivate safety devices of
the machine.
Check the machine regularly for damage, espe-
cially the safety devices.
Danger of cutting and burning
Always wear gloves when performing manual work
on the machine or with blanks / tools.
Only touch tools on the shaft.

Your E4 uses the following interchangeable tanks:
nCooling liquid tank for wet machining
nDry tank for dry machining (extra equipment)
Extra equipment can be obtained from your customer
service provider.
Depending on the machining mode, the required tank
must be located in the compartment below the
working chamber.
Without a dry tank in place, a connected air extraction
system does not generate the required vacuum in the
working chamber.
