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 the screw
with the torque specified in paragraph 8.4.
8.1

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 two sliding washers slightly on both sides with orthosis joint
grease.
3 Place the sliding washers onto both sides of the system stirrup (fig. 3).
4 Slide the system stirrup from below into the joint case (fig. 4). Make sure
that the sliding washers remain in the right position. To do so, use the sliding washer
centring pin.
Make sure not to damage the sliding washers during the assembly. Jammed
sliding washer particles can cause lateral play in the system joint.
5 Put the bearing nut into the joint case. The bearing nut must be fully inserted in
the opening (fig. 5).
6 Place the cover disc onto the joint case's front.
7 Screw in the countersunk flat head screw (S1; fig. 6).
8.2

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.
8.3

Mounting the Spring Units

1 Screw the spring unit for dorsiflexion into the anterior spring duct until the
required alignment of the orthosis is achieved (fig. 7).
2 Screw the spring unit for plantar flexion into the posterior spring duct until
it touches the system stirrup. Do not preload the spring unit.
