M3. Drain the water separator by turning the discharging
screw counter-clockwise.
The condensate is blown out downwards under pres-
sure.
M4. Close the discharging screw again by turning it clock-
wise.

6.8.2 Exchanging / cleaning the contaminated filter
cartridge
You have to clean or exchange the filter cartridge in the water
separator in case of strong contamination.
A strongly contaminated cartridge can lead to a pres-
n
sure loss.
If the compressed air fulfils the requirements for air purity
according to ISO 8573-1, the filter cartridge usually does not
have to be changed.
h If the filter cartridge is contaminated, check the purity of
your compressed air (

You exchange or clean the filter cartridge as
follows:
M1. Disconnect the machine from the compressed air sup-
ply.
M2. Unscrew the bowl of the water separator.
M3. Untighten the filter screw below the filter cartridge.
M4. Pull out the filter cartridge and clean it if necessary.
A new filter cartridge is available as spare part from cus-
b
tomer service.
M5. Insert the new or cleaned filter cartridge and reassem-
ble the water separator.

6.9 Exchanging the main fuse

Only use fuse type 250V/5Asb as a replacement fuse.
n
The internal power supply of the K4 edition has a main fuse
that is accessible from the outside and can be replaced if nec-
essary.
A new main fuse is available as spare part from custom-
b
er service.
M1. Turn off the machine at the main power switch and dis-
connect the machine from any electrical source and the
compressed air supply.

Machine maintenance and cleaning
M2. Remove the power cord from the connection panel.
M3. Remove the cover of the fuse.
Fig. 29: Cover of the fuse (marked orange)
M4. Remove the defective fuse and replace it with a new
fuse of the type 250V/5Asb.
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.
M5. Remount the fuse cover.

6.10 Calibrating the axes

NOTICE
Deterioration of machining results caused by an
incorrect calibration
The machine is already calibrated at delivery. As long as your
machining results are without flaw, a new calibration is not
necessary. A calibration takes much time and can deteriorate
the machining results in the worst case if it is not done cor-
rectly.
h In case of inaccurate machining results, try adjusting the
working conditions first: check the fixation of the blank,
the state of the tool or of the processing material.
h Before calibrating the machine, contact customer ser-
vice.
h Be very careful when measuring and entering data
during calibration. When in doubt, stop the calibration.
With test and calibration specimens you can measure and, if
possible, improve the machining results of the Machine.
The documentation for the manufacturing software
b
contains all information on calibrating the machine.
Therefore, you will only find information specific to the
K4 edition in this document.
Your K4 edition is delivered with a calibration set. It contains
the following parts:
Calibration discs which you use to mill calibration and
test specimens
A tool for milling the calibration or test specimens
A micrometre for measuring the machining precision
