6. Pneumatic connection
For the operation of the 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 6bar.
In case of a too high loss of pressure:
–Increase the compressor output.
–Increase the diameter of the compressed air hose.
Connecting the maintenance unit for compressed air
–Connect the connection hose (Order No. 0797 003031) to the
pressure regulator 3 by means of a hose coupling ¼ “.
Adjusting the operating pressure
–The operating pressure amounts to 6 bar.
It can be read off at the manometer 2.
–For adjusting the operating pressure lift the twist handle 1
and turn it.
–Turning in clockwise direction = the pressure is increased
–Turning counter-clockwise = the pressure is reduced
ATTENTION !
No oil-bearing compressed air must be fed from the compressed air
line.
Behind the filter cleaned compressed air is withdrawn as blowing air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.
