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 8.6. The assembly is illustrated with the NEURO FLEX MAX
system knee joint with lock function as an example.
The locking pawls/step lock pawls are assigned to specific system
joints. You will find the article number of the premounted locking
pawl/step lock pawl on the back page of these instructions for use.
8.1

Mounting the Extension Stop

If you would like to mount another extension stop than the premounted 5°
stop (fig. 12), proceed as follows:
1 Screw the pan head screw through the threaded hole in the back of
the joint's upper part (fig. 13).
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 align-
ment of the entire orthosis. File the flexion stop at the flexion
stop disc or at the joint's lower part so that it corresponds
with the mounted extension stop. In order for an exchanged
extension stop not to affect the orthosis alignment negatively,
also correct the system ankle joint, if necessary.

Mounting the Pressure Spring and the Locking Pawl/Step Lock Pawl

1 Mount the pressure screw (fig. 14).
2 Insert the pressure spring from below into the spring duct of the
joint's upper part (fig. 15).
3 Grease the axle bore of the locking pawl/step lock pawl and the
friction surfaces of the pawl's bearing nut with orthosis joint grease.
4 Put the bearing nut for the locking pawl/step lock pawl into the
intended opening of the joint's upper part (fig. 16).
5 Mount the locking pawl/step lock pawl (fig. 17).
6 Place the ball and push the locking pawl/step lock pawl upwards
(fig. 18).
