5.6 Installing the pneumatics
WARNING
Risk of injuries through
leaking compressed air and
lashing pneumatic hoses
Open or loose pneumatic connections can cause
severe injuries.
Ensure that
during installation and maintenance
of the pneumatic hoses and of the compressed air
regulator compressed air is not conducted through
the hoses and connections.
Before
conducting compressed air through the
hoses and connectors, verify that the hoses are
securely inserted into the correct connectors and
that they are not damaged. This also applies to the
compressed air regulator.
Do not conduct compressed air through damaged
hoses and connectors.
NOTICE
The spindle may suffer
bearing damage and electrical
damage if the compressed air is contaminated
The incoming compressed air must be dry and oil-free
according to ISO 8573-1:2010 because the
compressed air regulator only serves as an
indicator
for contaminated air.

Ensure that the compressed air meets the above
requirements.
Only connect the machine to the compressed air
supply if the compressed air regulator is properly
installed.
Connect the machine to the compressed air supply
only via the provided compressed air regulator.
You can find specific values and additional require-
ments in the chapter on technical data.
The machine requires the compressed air for the
following tasks:
n
For the opening and closing of the collet chuck
during tool changes.
n
For the spindle sealing air which prevents foreign
bodies from entering the spindle.
n
For the sealing air in the working chamber that
keeps machining debris away from sensitive
machine parts.
n
For the ionizer.
