Assembly Instructions

The system joint is delivered fully assembled. All functions are checked beforehand. You
have to disassemble the system joint for mounting it in the orthosis and for maintenance.
To ensure an optimal functioning, follow the assembly instructions below. Secure all screws
with the torque specified in paragraph 8.7. The assembly is illustrated with the
NEURO VARIO zero system knee joint as an example.
8.1 Mounting the Extension Stop NEURO VARIO zero and
NEURO VARIO
For system knee joints without exchangeable extension stop, skip these steps and start the
assembly at paragraph 8.2.
If you are using a system knee joint with an exchangeable extension stop and would like to
mount another extension stop than the premounted 5° stop (fig. 8), proceed as follows:
1 Screw the pan head screw through the threaded hole in the back of the joint's upper
part (fig. 9).
2 Press out the extension stop.
3 Remove the pan head screw.
4 Put the new extension stop into the joint's upper part.
5 Press the extension stop into the joint's upper part by using a vice with braces.
When mounting the extension stop, mind the correct alignment of the entire
orthosis. In order for an exchanged extension stop not to affect the orthosis align-
ment negatively, also correct the system ankle joint, if necessary.

Mounting the Cover Plate

Make sure not to damage the sliding washer during the assembly. Jammed sliding
washer particles can cause lateral play in the system joint.
1 Clean the threads of the joint's upper part and of the bearing nut after laminating with
LOCTITE® 7063 Super Clean. Allow the threads to air-dry for 10 minutes.
2 Grease the axle bore of the joint axis and the friction surfaces of the bearing nut with
orthosis joint grease.
3 Put the bearing nut of the joint axis into the opening of the joint's upper part (fig. 10).
4 Grease the first sliding washer slightly on both sides with orthosis joint grease.
