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 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 separate-
ly 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.
Mounting the Spring Units for NEURO SWING 2
1
Assemble the stop damper (2) and the sliding bushing (3) with the plunger (1; fig. 15).
2
Put the pressure spring (4) on it.
3
Insert the plunger (1) including the assembled system components (2, 3 ,4) in the spring duct.
4
Stick the screw unit (6) onto the spring unit (5).
