DANGER
Strictly adhere to the instructions in the DANGER text in Section 2.2.
In the case of dismantled component table / component changeover table / dismantled WPC, it is
also true:
High risk of injury exists from stationary blade and movable blade and the tape deflector of the
cutter, even when the machine has been turned off.
Never reach into the pneumatic cutter from below or into the empty-tape duct from above, not
even to resolve a problem (e.g., when tape is jammed).
Å Move the conveyor to maximum width (if a dual conveyor is installed:
conveyor (1 and 2), so that you will be able to remove the lifting table(s) plate during a subse-
quent step.
Å Afterwards the lifting table plate must remain lowered so that the springs of the holddowns are
not under tension.
Å First, position the gantry or gantries over the area of the PCB conveyor such that you can re-
move the WPC, the component changeover table or the movable component changeover table
out of the machine without damaging the placement head.
NOTE:
At F4, F4-6, F5: The changeable component table (next to the WPC) can remain installed since
there is enough access room to work on the PCB conveyor after the WPC is removed.
Å Disconnect the movable component changeover table from the machine now and move it out
of the machine.
Å Turn the machine OFF, disconnect the machine from the mains and turn off the flow of com-
pressed air at the compressed air unit. Actuate the needle valve to bleed the compressed air
lines (see DANGER text in Section 2.2).
Å If a (non-movable) component changeover table has to be removed, use a pallet truck to move
it out of the machine or move the WPC out of the machine.

Where applicable, dismantle the component table (1 or 2).
Å Remove the tape waste chute (just hooked in at F5).
-> This makes the PCB conveyor easier to access.
Å At SIPLACE 80 F4 / F4-6/F5:
Å Lift out the nozzle changer for the IC head.
Å Lift off the top-mounted attachment of flip-chip camera and IC camera.
Å For the time being, put these attachments and the nozzle changer down in a secure place.
Å Conscientiously cover the area of the camera and the coplanarity sensor, e.g., with a large,
clean cloth or carton.

NOTE:
The lifting table plate must be removed, for example, in order to exchange the holddown device
from retroft kit and to make the electrical connection of the centering unit at the PCB conveyor
control.
The PCB conveyor is already set to maximum width.
Å Move the Y-gantry / Y-gantries into the area outside the PCB conveyor.
Å Remove the reinforcing rail from the movable conveyor side (inside).
Å In the pertinent conveyor area, on the fixed
DQG
the movable conveyor side, slightly loosen the
M3 setscrew on the ball bearing of each rocking lever on LH and RH (see Fig. 2.4.1 -> 2 to 5).
Å Being careful not to misplace the setscrew and the spacer disk, remove the two ball bearings
and the spacer disk under them from each rocking lever).
WARNING
During the subsequent lifting of the lifting table plate there is a risk of body members being
pinched, crushed or cut off, e.g., between the outer edges of the lifting table plate and the con-
veyor assemblies. Wear strong protective gloves.
Å Holding the lifting table plate with both hands, lift it up vertically.
Å Make certain the lifting table is not tilted while being lifted.
Å Place the lifting table plate upside down on a clean, flat surface.
