Mounting The System Stirrup; Checking The System Joint's Free Movement; Mounting The Spring Unit - FIOR & GENTZ NEURO CLASSIC-SPRING Notice D'utilisation

8.3 Mounting the System Stirrup

1 Grease the friction surfaces of the bearing nut as well as the contact surfaces
of the system stirrup between system stirrup and spring units with orthosis joint
grease.
2 Grease the second sliding washer slightly on both sides and place it on the
system stirrup so that there is one sliding washer on each side (fig. 10).
3 Slide the system stirrup from below between the cover plate and the joint's
upper part. Make sure that the sliding washer remains in the correct position.
4 Put the bearing nut into the joint's upper part. The bearing nut must be fully
inserted in the opening (fig. 11).
5 Screw in the second countersunk flat head screw (axle screw, S2; fig. 12).

8.4 Checking the System Joint's Free Movement

Check if the system joint moves freely. If the system joint runs with lateral play,
mount the next thicker sliding washer. If it does not move freely (it is jammed),
mount the next thinner sliding washer.

8.5 Mounting the Spring Unit

For system ankle joints without a spring unit, skip these steps and continue the
assembly at paragraph 8.6. Please note that the mounting of the spring units for
the NEURO SWING 2 system ankle joint is described separately in this
paragraph.
1 Stick the screw unit onto the spring unit (fig. 13).
2 Screw in the sub-assembly in the spring duct (fig. 14). If the system
joint has two spring units, first screw the sub-assembly for the dor-
siflexion into the anterior spring duct until the required alignment
of the orthosis is achieved. Continue with screwing the spring unit
for the plantar flexion into the posterior spring duct until it touches
the system stirrup. Do not preload the spring units.
3 Make sure that the system joint is aligned with the degree marking.
