The compressed air working pressure is set to 5.3 bar + 0.2 bar. The position of the compressed
air unit is indicated by item 4 in fig. 2.4 - 1
. The compressed air supply to the machine can be
interrupted using the shut - off valve (item 1 in fig. 2.4 - 1
).
Å Open the protective door.
Å You must remove the cover plate to use the shut - off valve.
Å Turn the lever on the shut - off valve (item 1 in fig. 2.4 - 1) from the vertical to the horizontal
position.
Å Watch the working pressure gauge and the pressure gauge for the compressed air supply of
the stopper (item 2 or 3 in fig. 2.4 - 1
).
– If the automatic placement system is switched on, the pressure discharges to 0 bar within 1
minute.
