Before starting any repair or maintenance work on the radioscopy operation table it might be necessa-
ry to take off the table plate, to prevent damages. In some cases this will become absolutely necessary
in order to reach special parts.
Adjust the table in the highest position and carry on as follows:
Adjust the table at the headboard with the help of the sliding
mechanism. You will now see the guide rails for the sliding
mechanism under the table top.
unscrew the eight screws.
Then drive the table plate to the end of the foot board. You
will now see the guide rails for the sliding mechanism.
unscrew the six screws.
The cylinder piston for the hydraulic sliding function has to
be taken off. To do so, put off the screw at the end of the
piston.
Note:
To put off the screw, push against the screw with a screwdri-
ver or similar. The piston itself is freely movable.
Finally move the table plate to the left (1 x) and to the right
(1x) in order to put off the last two screws through the notch
in the base plate.
Now the plate can be easily removed.
Attention:
before removing the last screws, a second person
should secure the table top to prevent the table top from
falling down.
In such a case serious injuries or damages of the table
top could be the result.
When remounting the table top, all screws should be
fastened first and then should be loosened by a half
turn.

To replace the hydraulic cylinder for the longitudinal shifting, first take off the table top as stated in Chapter III
“Removing The Table Top“.
Then remove the crusting protector and loosen the expansion bellows. For further information please see
Chapter IV „Removing The Crusting protector“, Chapter V“ Removing The Column Cover“ and Chapter
VI “Loosening The Expansion Bellows“.
Do as follows:
Loosen the threaded joint at the end of the hydraulic cylinder.
Note:
While loosening the screw, the piston has to be supported
with a - e.g.- screwdriver in order to disconnect the threaded
joint.
Now remove the fastening screws of one of the two guide
rails of the hydraulic cylinder block.
As soon as the guide rails are taken off the cylinder block can
be removed.
In case the hydraulic cylinder is faulty it now can be replaced
by removing the screws of the tube connection.
After removing the screws, the tube can be easily removed
from the block.

Should the tubes be faulty, they have to be retraced to the
tube connection (quick acting coupling).
You will find those connections in the center part of the table
column.
To separate the couplings just pull the spring of the coupling.
Note:
There will be no penetration of oil while separating the coup-
lings, as they are equipped with a return valve.
Attention:
while working with tubes of the shifting function it is ab-
solutely necessary to install them exactly as provided by
the manufacturer, to prevent damages on the shifting
function.
Note:
We recommend to replace the tubes one by one to make
sure they will be properly installed. Separate the tube from
the coupling and connect the new tube right away. Install the
new tube while dismounting the faulty tube.
This procedure will guarantee the proper installation of the
tube.
Always take care of cable ties and band clamps.

the guide rails. That would destroy the guide rail system
and render it useless!
Move the base plate by hand to the left side until you will be
able to reach the screws, which connect the guide rails to
upper base plate, from underneath. (3x screws/ rails).
As soon as this procedure is carried out, do the same on the
opposite side.
Attention:
Before removing the last screw, a second person should
secure the base plate, as it is no longer connected to the
frame and therefore prevent it from falling down.
When all fastening screws are removed, the upper base plate
can be detached from the frame.
