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.  Technical
data – on page13
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.
Overview compressed air regulator
The machine is connected to the external air supply
via a compressed air regulator. You can use this regu-
lator to monitor and regulate the pressure of the
incoming air.
The compressed air regulator is supplied with the
machine and needs to be mounted on the side of the
machine housing when installing the machine. The
regulator has the following connections:
n 1/8” internal thread, fitted with male compressed
air connector to connect the external compressed
air supply
n 6 mm push-in fitting to connect the machine.
NOTICE
Failure of the water separator caused by a wrong
alignment of the compressed air regulator
The compressed air regulator must always be
mounted in an upright position because otherwise
the water separator will not work.
Mount the compressed air regulator in an upright
position.
On the left side of the machine are two bores which
you can use to mount the compressed air regulator on
the machine.
Mount the compressed air regulator in an upright
position, using the oval-head screws provided in
the bores.
