5. Stabilizer [00358684-xx]
The stabilizer enables the lifting table to be moved gently
upwards. It prevents the PCBs from being clamped in
with too much impact.
The stabilizer consists of the shock absorber [00367737-
xx] and the damping block [00367782-xx].
► Move the PCB conveyor to the position which gives
you best access to the lifting table.
► Move the Y gantries into the area outside the PCB
conveyor.
► Switch off the machine and secure it to prevent unau-
thorized reactivation.
► Loosen the screws fastening the lifting table plate and
remove the lifting table plate from the lifting table unit.
► Loosen the two screws (3) holding the stabilizer (5).
► Undo the locknut (2) and take the stabilizer by its han-
dle (4), twisting it out of the mounting block.
