Replacing double castors
The operating tables are equipped with four electrically
conductive double castors. The double castors can be
replaced.
Preparation

In order to replace one of the double castors, remove
the cladding panels at the height adjustment column.
You will find details in the chapter “Removing and re-
attaching the cladding panels” on page 11.
•
Lift the cladding off the mobile base. You will find
details in the chapter “Removing and re-attaching the
cladding of the mobile base13
Dismounting the double castors
In order to dismount one of the double castors, loosen the
hexagonal shaft between the double castors.
•
Loosen all the Allen screws at the components on the
hexagonal shaft, so that the hexagonal shaft can be
moved to the left or to the right inside its bearing.
•
Swivel the pedal for the brake and for the directional
castor into mid-position and drive the hexagonal shaft
of the double castor out.
•
Loosen the fastening screw at the bearing; lift the table
up and pull the double castor down and off.

Caution!
Once one of the castors has been removed, the
table may tilt and thus cause injuries. Make sure
to prop the operating table carefully up.
•
Prop the operating table up.
Installing the double castors
The locking direction of the new double castor is indicated
by means of a sticker. Install the new double castor in
mid-position and the direction of locking pointing away
from the pedal end of the table.
•
Mark the locking direction of the double castor and
bring the new castor into mid-position by means of a
spanner for hexagon nuts.
•
Push the new double castor into the holder in such a
way as to make its locking direction point away from
the pedal end of the table.
•
Screw the fixing screw at the holder in; push the
hexagonal shaft through and fasten all the
components to the hexagonal shaft.
Final tasks
•
Make sure that the brake and the directional castor
work correctly.
•
Place the cladding back on top of the mobile base.
