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).
2.2 User skills

2.3 Incorrect operation of the
machine
Before installation, putting into operation and main-
tenance of the machine, read all the documents
provided for the machine.
If the operation of the machine is unclear in whole
or in part, do not use the machine and contact
customer service.
Make sure that every user has access to this docu-
ment.
Instruct every user on safe and proper machine
handling.
2.4 Personal injury
2.4.1 Electric shock
Electrical shock by touching live parts
Do not remove the housing of the machine.
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.
Check the power cable for damage before every
startup.
In the following cases, disconnect the machine
immediately from the electrical source and secure
it against restarting:
nWhen machine connections or electric cables are
damaged
nBefore you check or run electric cables
Do not touch the machine and especially the
cables with wet or damp hands.
Do not place any liquid containers on the machine.
Electric shock when disconnecting the power cable
with the main power switch in “ON” position.
Follow the following sequence:
1. Switch off the machine via the main power switch.
2. Disconnect the power cable.
2.4.2 Fire hazard
Unattended operation
Do not operate the machine unattended unless:
nThe working chamber of the machine is com-
pletely cleaned.
Original Operating Instructions:E5
Version: 2/10/2023
General safety instructions
EN 6

nUnauthorized persons have no access to the
machine.
nThe room in which the machine is located has an
automatic fire detection system.
2.4.3 Housing
Danger of entrapment by moving housing parts
nWorking chamber door
nUpper and lower servicing cover
If you move these housing parts, use only the desig-
nated grip points.
Make sure that your hands are not trapped during
movement.
2.4.4 Working chamber
Risk of crushing due to moving machine parts in the
working chamber
Only operate the machine with the working
chamber door fully closed and intact.
Do not bypass or deactivate the 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.
Do not touch the spindle body after machining.
2.4.5 Air extraction system
Respiratory disease when machining harmful
materials
Always use a suitable air extraction system during
dry machining.
Use a suction unit with fine dust filter class M.
Avoid materials that harm your health.
2.4.6 Operating noise
Hearing loss and tinnitus due to regular loud
working noises
If loud working noises cannot be prevented, use an
ear protector during machining.
2.4.7 Maintenance and troubleshooting
Risk of injuries from machine malfunctions due to
inadequate or incorrect maintenance/
troubleshooting
Perform the maintenance tasks according to the
maintenance table.
Do not troubleshoot while the machine is running.
2.4.8 Spare parts, extra equipment and
accessories
Risk of injury due to unsuitable spare parts / extra
equipment / accessories
Use only original spare parts, original extra equip-
ment and original accessories for the machine.
2.5 Material damage
2.5.1 Spindle
Damage caused by the warm-up phase being
omitted
When initially starting a machine or if it has not been
used for at least 2 weeks, you must warm the spindle
before use.
Use the warm-up process in DENTALCNC.
The DENTALCAM & DENTALCNC user Information
provides instructions on how to do this.
Damage due to poor maintenance
Clean and replace the collet chuck according to
the maintenance table.
Damage caused by unsuitable tools
Recommendation: Use only original tools from vhf.
Use tools only within the maximum lifetime shown
in DENTALCNC.
See the requirements in the chapter Technical data.
Impact damage
When working in the working chamber, do not
apply force to the spindle in any way.
2.5.2 DENTALCAM & DENTA LCNC softw are
Machine damage due to incompatibility,
malfunctions and/or incorrect operation of the
software
Always use the latest version of the program that
your machine supports according to vhf.
Ensure that your CAM computer meets all system
requirements.
Before installing or operating the machine, read
the documentation for the programs.
2.5.3 Pow er
Damage to the control electronics due to strong
mains voltage fluctuations and voltage peaks
Connect the machine to a separately protected
circuit or ensure that no devices are connected that
cause severe mains voltage fluctuations when
powered on.
If strong voltage fluctuations cannot be avoided,
General safety instructions EN 7
Original Operating Instructions: E5
Version: 2/10/2023

install a surge protector to safeguard the machine
against strong voltage fluctuations.
2.5.4 Air extraction system
Machine damage during dry machining without an
air extraction system
Always use a suitable external air extraction system
during dry machining.
2.5.5 Working chamber
Damage to tools and blanks as well as faulty
machining results due to job cancelations
Ensure that all operating parameters are within the
permissible range during the entire machining
process.
Make sure your network is non-disruptive. Wireless
connections are not as reliable as wired networks.
Machine damage caused by broken tool and blank
parts
Carefully check all blanks and tools for damage.
2.5.6 Working chamber door
Damage caused by improper handling
Only open a locked working chamber door via
emergency release.
