CAUTION 2
To avoid losing data, assess the following criteria before switching off your machine (apart from in
emergencies):
– Has the machine finished transmitting machine, setup and panel data?
– Has the machine finished processing the PCB?
– Has the machine completed the run-up phase?

2.9 Disabling the compressed air supply and discharging
the pressure
The compressed air working pressure of the machine is set to 0.50 ± 0.025 MPa (5.0 ± 0.25 bar).
The position of the compressed air unit is shown at item 1 in fig. 2.9 - 1
, page 83 ) The supply of
compressed air to the machine can be interrupted with the shutoff valve (item 2 in fig. 2.9 - 1
, page
83
).
Use the machine key to release the cover lock.
Lift the cover (see fig. 2.9 - 1, page 83 ).
Turn the lever of the shutoff valve (item 1 of fig. 2.9 - 1, page 83) from the vertical to the hor-
izontal position.
Monitor the operating pressure manometer (item 5 in fig. 2.9 - 1, page 83 ). When the machine
is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.
CAUTION 2
When the machine is switched on, do not use the stop valve to interrupt the compressed air sup-
ply for more than 30 minutes. If you need to shut off the pneumatic system for longer in order to
carry out preventive maintenance or servicing work, you must switch the machine off at the main
switch and disconnect it from the power supply.
