•
Before replacing the lift motor for couch adjustment
make sure that the motor is actually defective.
•
For this check, switch the hexagon socket of the
liftmotor from channel 2 to channel 1.
•
If the motor does not work, it is out of order and
must be replaced.
•
If the motor works, the motor control unit or the
hand switch is defective.
Follow these steps to replace the couch adjustment motor:
•
Set motor to the end position where the couch
surface is completely horizontal.

Disconnect system from mains!
•
When the lift motor has been removed, the couch
surface must be protected against falling down!

control. To do so, first turn jack plug counterclockwise
as far as possible (e.g. using a suitable fork wrench),
then pull out the jackplug.
Loosen cable tie of the connection cable.
•
Remove pins b. + c. with self-locking screw.
•
Remove lift motor.
Note:
