8.14 Cleaning the housing

Damaging of the housing
NOTICE
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 neces-
sary.

8.15 Exchanging the main fuse

The internal power supply of the machine has a main
fuse that is accessible from the outside and can be
replaced if necessary.
As a replacement fuse, only use a fuse of the fol-
lowing type: T6,3A L250V
A new main fuse is available as spare part from
customer service.
1. Switch off the machine at the main power switch.
2. Remove the power cord from the connection
panel.
3. Remove the cover of the fuse.

4. Remove the defective fuse and replace it with a
new fuse.

5. If you do not have a replacement fuse ready, take
the replacement fuse from the right side of the fuse
cover and put it into the left side of the fuse cover.
6. Remount the fuse cover.

8.16 Calibrating the axes

Deterioration of machining
NOTICE
results caused by an incorrect
calibration
At delivery, your machine is already calibrated. As long
as your machining results are accurate, a new calib-
ration 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 calibrating the machine, contact customer
service.
Be very careful when measuring and entering data
during calibration. When in doubt, abort the cal-
ibration.
By calibrating the machine with test and calibration
specimens, it may be possible to improve the
machining results. Customer service will assist you
with this.
Your machine is delivered with a calibration set.
Customer service will need this set for calibration. It
contains the following parts:
Calibration blanks which are used to mill cal-
n
ibration and test specimens
A tool for milling the calibration or test specimens
n
A micrometer for measuring the machining pre-
