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?
2.8 Disabling the compressed air supply and discharg-
ing the pressure
The compressed air working pressure of the machine is set to 0.51 ± 0.01 MPa (5.1 ± 0.1 bar).
The position of the compressed air unit is indicated by Fig. 2.8 - 1
. The compressed air supply to
the machine can be interrupted using the shutoff valve (item 1 in Fig. 2.8 - 1
).
→ Use the machine key to release the cover lock.
→ Lift off the cover (see Fig. 2.8 - 1
).
→ Turn the lever on the shutoff valve (item 1 in Fig. 2.8 - 1
) from the vertical to the horizontal
position.
→ Watch the working pressure gauge (item 4 in Fig. 2.8 - 1
). When the machine is switched on,
the pressure discharges to 0 MPa (0 bar) within 1 minute.
CAUTION
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.

WARNING
NEVER detach compressed air lines while they are still pressurized. Risk of injury. 2
