NOTICE
CAUTION
The incoming compressed air has to be dry and oil-free according to
ISO 8573-1, since the water separator can filter only small amounts. Wet
compressed air can lead to bearing damage and electrical damage of
the spindle.
Connect the machine to the compressed air supply only via the pro-
vided service unit.
Air purity according to ISO 8573-1:
Solid particles
Water content
Residual oil content
The compressed air supply has to provide at least 6 bar during operation of
the machine.
Connecting the service unit
The service unit can be mounted to the housing or connected directly to the
compressed air supply. You need to make sure that the service unit is visible
during operation so that a regular control is possible. In the following text the
mounting to the housing is explained. If you connect the service unit directly
to the compressed air supply, please regard only the steps M3. to M5.
The service unit
(see Illustration 4 on page 22). The water separator doesn't work, if the
service unit is not installed vertically!
M 1. Remove the two blind screws under the ventilation holes at the side
of the machine.
M 2. Mount the service unit vertically with the included cylinder head
screws (see Illustration 5 on page 24).
Connect the maintenance unit to the machine before you connect the
maintenance unit to the compressed air supply. Otherwise risk of injury oc-
curs through leaking compressed air or lashing pneumatic hoses.
M 3. Cut a piece of the delivered pneumatic hose (Ø 6 mm) in the desired
length.
M 4. Connect the pneumatic connection on the right side of the mainte-
nance unit to the pneumatic connection of the machine.
M 5. Connect the compressed air supply to the standard pneumatic con-
nection on the left side of the maintenance unit.
