Machine maintenance and cleaning
M11. Insert the measuring pin into the collet chuck with one
hand and keep holding it. Screw the collet chuck with
the knurled nut in your other hand tightly into the spin-
dle.
n
In any case, turn the knurled nut as far as you can so
that the collet chuck is properly seated in the spindle.
Otherwise rotational imperfections can occur during
operation which will worsen your processing results.
M12. Remove the measuring pin from the collet chuck and
store it together with the other components of the
spindle service set.
M13. Close the working chamber door.
6.6 Checking the hoses, cables and connections
M1. Disconnect the machine from the electrical source and
the compressed air supply.
M2. Check the hoses and cables that are connected to the
machine.
M3. In case of damages prevent the machine from being
restarted. Replace the damaged cables and hoses im
-
mediately with original replacement cables. Contact
cus
tomer service.
M4.
Verify all connections on the connection panel (e. g.
loose connections).
M5. Re-insert loose cables and hoses tightly into the corre

sponding connections. In case of damaged connections
cease use of the machine
immediately. Contact custom-
er service.
6.7 Cleaning the housing
NOTICE
Damaging of the housing when using a non-
recommended cleaner
If you use an unsuitable cleaner for cleaning the machine
housing, the surface or the adhesive foil can get damaged.
h Avoid contact of the powder coating with alkaline or acid
substances. Especially metallic powders show a highly
sensitive reaction.
h Take care of the glued symbols so that they do not peel
o.Theadhesivefoilisespecially sensitivetorubbing
and strong detergents.
h If the usage of a special cleaner is necessary to eliminate
certain dirt, we recommend checking the suitability of
thecleaneratahiddenplaceofthepartrst.
M1. First, clean the powder coated surface with a soft, dry
cloth.
M2. If some dirt cannot be removed this way, moisten the
cloth. Use a pH neutral cleaner if necessary.
6.8 Checking the service unit
NOTICE
Damaging of the machine when compressed air
is contaminated
Compressed air that does not full the guidelines for pu-
rity according to ISO 8573-1 can damage the machine
(
 page 13).
h Check the water separator of the service unit daily for
contamination.
h Never use the machine if there is water, oil or solid parti
-
cles in the water separator.
6.8.1 Checking the water separator for condensate
Condensate in the separator usually points to compressed air
not being dry enough.
M1. Check if water, oil or solid particles piled up in the wa

M2. Check the compressed air supply and make sure that
thecompressedairfullstherequirementsforairpu
-
rity according to ISO 8573-1 (
 page 13). Do not
usethe machine until the compressedair fulls this
