Removal
CAUTION
Only on the single conveyor!
The lifting table motor may only be replaced on single conveyors.
The lifting table motor may not be replaced on dual or quad lane conveyors. In these cases,
you may need to replace the entire lifting table.
CAUTION
Do not loosen the lifting table mechanism
The lifting table mechanism has been factory fitted with adjustment shims. Do not remove
these.
The only exception is the lifting table motor on the single conveyor.
NOTICE
Lifting table plate fixtures
► Mark the positions of the lifting table plate fixtures.
If these are still mistakenly exchanged, you will need to reset the parallelism of the lifting
table plates after installation.
► Remove the lifting table from the machine. (See
"3.6.4 Replacing the Lifting Table Unit" [ ➙ 101])
► Unplug the connection between the motor and the
rods (1).
► Loosen the screws (2) fastening the motor. Some of
these are only accessible if you move the rods up-
wards (thereby turning the gear shaft by 90 degrees).
CAUTION!
Make sure that you do not loosen the other four screws!
► Remove the motor.
CAUTION!
There are several shims on the gear shaft. These need to
be taken over to the new motor and fitted there in the
same positions and quantities.
