Replacing the gas springs at the back section and repairing the release
mechanism
The back section of the OPX mobilis 200, mobilis 300
and mobilis RC 30 operating table models can be
adjusted against the counterpressure of two gas springs.
The RC 40 model does not have gas springs for back
section adjustment, but hydraulic cylinders. You will find
details regarding replacement of the hydraulic cylinders
in the chapter “Replacing the hydraulic cylinders for back
section adjustment in the RC40 models” on page 35.
The gas springs are installed in the left and right hand
frame of the back section. At the top of each gas spring
there is a trigger head, which is activated by means of a
hydraulic cylinder.
When the gas springs are released, a hand lever exerts
pressure onto a hydraulic cylinder. The pressure
developed is directed via hydraulic hoses to the two
trigger heads at the gas springs. This way the gas springs
are released simultaneously and can be adjusted.
The trigger heads at the top of the gas springs serve at the
same time as bearings.
In order to start the bearing bolts a special drift bolt is
required, which can be prepared according to the
measurements given in the following drawing.

In an emergency it is also possible to use a long
screw and a pair of pliers.
Preparation
•
Fold the back section on top of the seat section. You
will find details in the chapter “Folding the back
section on top of the seat section” on page 29.
Removing the gas spring
The gas springs are fixed inside the frame of the back
section. The bearing bolts with female thread are secured
by means of headless screws.
•
Detach the claddings together with the push handles
at the underside of the back section.
