Important: assembly requires serial number. Note chapter 27 on
page 276.
Disassembly 1. Prepare the operating table (see chapter 7 on page 29).
2. Switch off the operating table and disconnect the internal
power supply (see chapter 10 on page 33).
3. Remove the pad plate of the seat section (see chapter 12.2 on
page 40). Important: keep the back section pad plate
attached so that the bar adjustment is retained.
4. Remove the drive unit of the leg section (see chapter 13.4 on
page 61).
5. Pay particular attention to the installation position of the motor
and to the feather key.
Release the ring nut on the motor [2] with a hook wrench and
pull the motor [2] out of the gear box [1].
Assembly 1. Address the new motor (see the software description from the
CAN test center).
2. Make sure to re-install the motor in its original position.
Align the lugs on the motor flange with the recesses on the
gear box (connection sockets on the motor are on top), rotate
the motor shaft until the feather key lines up with the slot in the
gear box, precisely insert the key into the slot of the motor shaft,
and then slide the motor into the gear box up to the end stop.
3. Tighten the ring nut on the motor and fixate the connection with
screw coating (#4150041) (at least three application points
evenly distributed across the diameter.)
4. Attach the leg section drive unit to the seat section bar (see
chapter 13.4 on page 61).
5. Attach the pad plate to the seat section bars (see chapter 12.2
on page 40).
6. Establish the internal power supply, close the column cover
and turn on the operating table (see chapter 10 on page 33).
7. Put on the pad.
8. Calibrate the leg section motor (CAN test center). See
chapter 24.3 on page 266.
