4.5.25 Replacing the Vacuum Hoses on the C&P Head
The length of the vacuum hoses and the way in which they are fitted has been improved to ensure that,
when the hoses are replaced - especially in X, D3 and HF machines - these hoses can be run in a
manner which will not interrupt the vacuum supply.

4.6.2 Preparing for Part Replacement
X End all placement operations on the placement system.
X Shut down the Windows NT operating system correctly, otherwise problems may occur when
restarting or data may be lost.
X Switch the placement system off at the main switch.
X Disconnect the machine from the power supply.
X Secure the machine to prevent it being switched on again and put up warnings signs to indicate that
service work is in progress.
WARNING:
NEVER disconnect compressed air lines while they are still pressurized. Risk of injury!
DANGER: The machine is supplied with 3 x 400 V~ (or 3 x 204 V~ / 3 x 230 V~ / 3 x 380 V~
/ 3 x 415 V~) ± 5 %, 50/60 Hz mains voltage.
Consequently, parts of the system carry potentially lethal voltages, even when it is switched off
at the main switch.
Incorrect handling of the machine can therefore result in death, severe injury or considerable
damage to equipment.
Measurements and repairs must always be carried out by appropriately qualified personnel.
Always follow the safety instructions in this manual.
Always follow the applicable accident prevention and VDE regulations (particularly DIN EN 60
204 part 1) or the regulations specific to your country.
Before starting any repairs, switch off at the main switch and disconnect the machine from the
mains power supply.
Secure the system to prevent it being switched on again. If these instructions are not followed,
you may be able to touch live parts, which could result in death or severe injury.
