There are 2 ratchet braces each located at the head and foot ends
of the guide column.
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. Grasp the column cover, remove the holding screw from the
Trendelenburg assembly and guide the cover carefully
downward.
4. Open the column cover at the top and slide it down (see
chapter 9 on page 31).
5. Remove the metal panel with the column keypad (see
chapter 14.2 on page 77).
6. Head-end ratchet brace (rear):
Note the installation position of the ratchet brace [1].
Caution: when the screws [2] are loosened, the pressure
springs [4] behind the plate [3] push it out. Remove the
plate [3] with the two pressure springs [4] and the ratchet
brace [1] (4 screws [2]).
7. Foot-end ratchet brace (front behind the Trendelenburg
assembly):
Caution: the column must be in the uppermost lifting position.

suspension [6] and press it upward so that the screws [2]
on the metal plate [3] are accessible. If the screws are not
accessible, use the CAN test center (PC) to move the main
lift of the operating table so that the screws on the ratchet
brace behind the Trendelenburg drive are accessible.

CAUTION
Risk of injury from sinking table top!
