Flexion Stop; Optional: Installing The Foam Cover - Otto Bock Kenevo 3C60 Instructions For Use Manual

Preparing the product for use

6.1.8 Flexion stop

The knee joint comes fitted with a flexion stop upon delivery. This reduces the maximum flexion angle by 8°, thus
preventing the socket from coming into contact with the hydraulic unit.
To limit the flexion angle, the knee joint can be equipped with the following flexion stops:
• 4H107 flexion stop (already installed): reduction of the maximum flexion angle by 8°
• 4H108 flexion stop (in scope of delivery): reduction of the maximum flexion angle by 16°
The flexion stop can be removed to increase the flexion angle. In this case, it must be ensured that the socket and
the hydraulic unit do not collide (see page 74).

6.2 Optional: Installing the foam cover

If a foam cover is used with the knee joint, a charging shaft has to be mounted so the charger can be applied.

4) Make an opening for the threaded rod in the marked area.
5) Insert the centring rod through the opening and screw it into the centring plate to the stop. (see fig. 5)
NOTICE! The two nuts are used to limit the screw-in depth and protect the charging receiver and must
not be removed.
6) Apply the hole cutter and rotate it clockwise to cut a hole. (see fig. 6)
7) Unscrew the centring rod.
8) Remove the foam cover.

Removing the flexion stop
1) Use an appropriate screwdriver to loosen the screws on both flexion stops (to
the left and right of the piston rod).
2) Remove both flexion stops from the joint together with the screws.
INFORMATION: Do not insert screws without flexion stops!
Inserting the flexion stop
1) Insert both flexion stops (to the left and right of the piston rod).
2) Secure the screws with 636K13 thread lock.
3) Insert the screws.
4) Tighten the screws to 0.6 Nm with the 710D1 torque wrench.
