Installation
► Loosen the screw fastening the lifting table plate and
remove the lifting table plate from the lifting table unit.
► Loosen the fastening screws for the solenoid valve
(4) and remove it from the lifting table cylinder.
► Loosen the grub screw at the end position proximity
switch (1) and push the end position proximity switch
out of the lifting table cylinder guide rail (2).
► Loosen the locknut on the piston rod (3) and twist the
piston rod out until it releases itself from the actuator.
► Loosen and remove the two screws fastening the lift-
ing table cylinder (2).

Replacing the Lifting Table Stabilizer (Stabilizer Unit) [00358684-xx]
Overview
Tools and equipment required
▪ Torque wrench with plug-in ratchet [00386175-xx]
▪ Plug-in wrench 16 mm [00386177-xx]

1. Actuator
2. Locknut
3. Fastening screws
4. Handle
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.

Overview
► Insert and twist the new stabilizer (5) until the plunger
just touches the actuator (1), so that the lifting table
can be gently moved upwards.
► Using the torque wrench:
Secure this position with the locknut (2) tightened to
8Nm.
► Check whether the stabilizer has been fixed onto the
mounting block with the locknut and that the stabilizer
plunger has a gap of approx. 0.1 mm to the actuator
(gap in untriggered mode). In this default setting, the
lifting table should move up gently.
► If this is not the case, loosen the locknut and turn the
stabilizer approx. one rotation into the mounting
block.
► Fit the lifting table plate.
► Start SITEST and move the lifting table up.
► The lifting table should move up gently i.e. you should
not hear the PCB clamping device audibly locking
into place and no clamping device error messages
should be issued.
► Check the speed of the lifting table cylinder and cor-
rect where necessary.
