Disassembly 1. Prepare the operating table (see chapter 7 on page 29).
2. Secure the star wheel (#1800121) on the right side rail
14)
of
the seat section.
Release the brake on the operating table (unlock the
operating table).
Attention: The quick connectors on the assembly can be
loosened and connected only if the floor locks of the wheels
are retracted, thereby relieving the hydraulic system.
4. Switch off the operating table and disconnect the internal
power supply (see chapter 10 on page 33).
5. Slide the multifunction tool [1] mounted as a T under the table
base [2].
6. Safety note: The operating table is extremely heavy; take extra
care not to strain your back when turning it on its side. A
second person is needed to turn the operating table on its side.
With the help of another person, lay the operating table over
onto the multifunction tool (side with the column keypad points
up) and set it on the star wheel.
Do not place the operating table on its side with the column
keypad pointing down. In this case, air would get into the
hydraulic hoses when the hydraulics were activated.
7. Important: the assembly [4] is attached to the cover [3].
Provide a suitable aid (for example a crate or carton) near the
table base so the assembly can be placed on it. The cables
are not long enough for the assembly to be placed on the
floor.
Remove the center cover [3] under the table base (4 screws
with washers) and store it carefully.
8. Disconnect the plug from the coil.

CAUTION
Risk of material damage!
The major force required to turn the table on its side can break
the extended foot locks of the brake. The operating table must
be unlocked before turning it on its side.
