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.
