5 Preparing the product for use
5.1 Assembly
Gluing in the system lamination joint bars
After adapting the connecting elements, the lamination joint bars must be glued into the system connection plugs
for reasons of stability:
1) Degrease the joining surfaces with 634A1 thinner or solvent.
2) Mix the 636W28 special adhesive and hardener.
3) Apply the mixture inside the system connection plugs.
4) Insert the lamination joint bars (9) into the upper joint section (4).
5) Fasten with 501T7=7.5x9xM5 oval head screws (8).
6) Allow to cure for at least 3-4 hours. INFORMATION: Final bonding strength will be reached after 16
hours.
Mounting the foot stirrup
1) Insert the foot component with foot stirrup (10) into the upper joint section (4).
2) Lubricate the bearing nut (3) with 633F7 special lubricant and insert it.
3) Apply Loctite® 241 to the thread of the truss head screw (2) and screw it into the bearing nut (3).
5.2 Adaptation
The system ankle joint is adapted to the needs of the patient through the individual combination of the bearing ball

e.g. with distinct hyperextension in the knee joint, but with additionally
adjustable damped dorsal stop
e.g. in case of weakness of the lower leg muscles
Dorsiflexion assist, e.g. in case of peroneal paralysis without own
muscular knee joint protection
e.g. in case of pareses of the lower leg muscles
e.g. in case of weakness of the lower leg muscles with tendency to
hyperextension of the knee joint
Dorsiflexion assist, e.g. in case of pareses of the lower leg muscles
without muscular knee joint protection
e.g. in case of pareses in the lower leg muscles with weakness of the
knee-protecting muscles
