Removal/installation
► Insert and fasten the new lifting table cylinder (2) and
install the piston rod (3).
► Move the lifting table by hand to its end position.
► Switch the machine on.
► Push the end position proximity switch (1) into the
guide rail until the LED lights up.
► Fix this position with the grub screw.
► Install the solenoid valve (4) and the lifting table plate.
Fasten any disconnected cables or hoses again, with
the cable ties.
► Check the speed of the lifting table and correct where
necessary.

► 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.

CAUTION!
Do not damage the toothed belt!
During the following removal and installation of the motor,
the toothed belt for the width adjustment drive must not
be stretched or kinked!
► Move the PCB conveyor to the position which gives
you best access to the stepping motor of the width
adjustment system.
► Move the Y gantries into the area outside the PCB
conveyor.
► Switch off the machine and secure it to prevent unau-

6.7.1 Setting the Tension of the Conveyor Toothed Belt and the Width Adjustment Unit [ ➙ 261]
► Loosen the screws fastening the lifting table plate and
remove the lifting table plate from the lifting table unit.
► Loosen the eccentric axle (1) on the deflection pulley
and relieve the tension on the drive toothed belt (5).
CAUTION!
Parallelism of conveyor side: Toothed belt must not come
off!
When relaxing the toothed belt, make sure the belt does
not come off (skip) the toothed disks at the 2 adjustment
units. This would cause incorrect alignment of the adjust-
ment units. Secure these positions with a suitable tool
(screw clamp etc.)
► Remove the 4 fastening screws (3) and then lift out
the stepping motor (4).
► Unplug the connection cable in the cable duct.
► Fit the new stepping motor and reconnect the system
to the electrical system.
► Tension the drive toothed belt.
► Position the measuring point of the belt tension de-
vice at the strand center (i.e. the longest distance be-
tween two toothed disks) of the conveyor toothed
belt.
► Adjust the tension of the drive toothed belt.
