2) Screw the magnetic bottom shell and the connection adapter to each other from the outside
with the cap screws (M6) (see fig. 27).
3) Tighten the cap screws with a torque of 10 Nm.
4) Re-tighten all screws by turns after 30 minutes and secure with 636K13 adhesive.
INFORMATION: When securing the screws, only loosen one screw at a time, apply the
adhesive to the thread and tighten the screw to the specified tightening torque.
The connection adapter can be installed in three positions depending on the flexion contracture.
Flexion contracture
None
Up to approx. 5 degrees
Greater than 5 degrees
The following conditions have to be met to ensure there is a strong connection between the mag­
netic bottom shell, medial side rail and connection adapter:
• All six screws always have to be used.
