2.7 Disabling the compressed air supply and discharging
the pressure
The compressed air unit is at location 2 (see fig. 4.4 - 1, page 187 ). The compressed air working
pressure of the placement machine is set to 0.51 ± 0.01 MPa (5.1 ± 0.1 bar). The position of the
compressed air unit is shown at item 1 in fig. 2.7 - 1
, page 99. The supply of compressed air to
the placement machine can be interrupted with the shutoff valve (item 2 in fig. 2.7 - 1
, page 99 ).
Use the machine key to release the cover lock.
Lift the cover (see fig. 2.7 - 1, page 99 ).
Turn the lever of the shutoff valve (item 1 of fig. 2.7 - 1, page 99) from the vertical to the hor-
izontal position.
Monitor the operating pressure manometer (item 5 in fig. 2.7 - 1, page 99 ). When the place-
ment machine is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.

CAUTION
Interruption to compressed air supply!
When the placement machine is switched on, do not use the stop valve to interrupt
the compressed air supply for more than 30 minutes.
If you need to shut off the pneumatic system for longer in order to carry out preven-
tive maintenance or servicing work, you must switch the placement machine off at
the main switch and disconnect it from the power supply.

2.8 Locking and attaching the warning labels
2.8.1 Purpose and scope
Before performing any preventive maintenance work or service work to the placement machine,
a procedure of locking and tagging must be followed. The following procedure, when followed cor-
rectly, eliminates the possibility of an employee being injured by electrical shock in connection with
unexpected movement.

2.8.2 Description
Whenever it becomes necessary to isolate, control and release energy for the placement ma-
chine, the following procedure is to be followed.
Notify affected employees.
Switch off the placement machine and any auxiliary devices. Carry out all normal stopping
procedures:
– Press the stop button.
– Shut down the control computer.
– Switch the placement machine off at the main power switch.
Isolate the placement machine from all its energy sources:
– Shut off the compressed air supply
– Shut off the main power supply
Lock out the machine.
– Attach a lock whenever possible (e.g. to the main switch).
PLEASE NOTE
Minimum requirements
These procedures represent the minimum lock/tag out requirements for the preventive
maintenance or service work on the placement machine. Any additional safeguards
needed to complete work safely can be specified by facilities supervision, the safety of-
ficer, the safety committee and the health department.
