3.7 Pneumatic connection
3.7.1 Connection to compressed air maintenance unit
For the operation of the pneumatic devices, the sewing machine must
be supplied with dry compressed air.
CAUTION!
To cater for correct pneumatic control processes, the compressed air
supply must be set up as follows:
“At the moment of max. air consumption, the minimum operating
pressure may not be below 5 bar.”
The supplied compressed air may not contain any lubricants. After the
air has passed the filters, cleaned compressed air is brought to the
machine for the blowing out of sewing pieces.
If the air were to contain lubricants, they would contaminate the sewing
part and result in disruptions.
–Connect compressed air maintenance unit 2 to the maintenance
unit by means of the connecting hose (Ø = 9 mm) and the G1/4"
hose coupling.
–
Pneumatic connection set
The pneumatic connection set is available as item no. 0797 003031
and is a pneumatic adapter set for frames with compressed air
maintenance units.
It contains the following components:
- connecting hose, 5 m long, (Ø=9mm)
