Pneumatic connection

For the operation of pneumatic components, the sewing unit has to
be supplied with anhydrous compressed air.
ATTENTION!
For a trouble-free function of the pneumatic control procedures, the
compressed air supply must operate as follows:
Even at the moment of the highest air consumption, the minimum
operating pressure must not drop below 6 bar.
In case of important drop of the air pressure:
–
Increase the compressor output.
–
Increase the diameter of the compressed air hose.

Adjusting the operating pressure
–
The operating pressure is 6 bar.
It can be read off at the manometer 2.
–
To adjust the operating pressure raise and turn handle 1.
–
Turn clockwise = increase pressure
–
Turn counter-clockwise = reduce pressure
ATTENTION!
No oil-bearing compressed air must be fed from the compressed air
line.
The cleaned compressed air after the filter is used as blowing air for
cleaning machine parts and for blowing workpieces out.
Oil particles contained in the blowing air lead to malfunctions and
stains on the workpieces.
