Maintenance of Carbon System Ankle Joints

You can find information on system components that have to be checked particularly carefully during maintenance in the instructions for use under “Maintenance”.

Only necessary for the NEURO SWING Carbon
Demount the spring units in order to examine them. Check if the system joint moves without lateral play.

Hold the lower leg shell and try to move the foot shell in pronation-supination direction.
If there is lateral play, this can indicate loosened screws and/or worn out sliding washers.

Check if there is play around the axis. If there is play, the bearing nut and the sliding bushing should be replaced if necessary.

Check if the system joint moves freely. Bring the system joint in plantar flexion/dorsiflexion.
If the system joint does not move freely, mount the next thinner sliding washer or clean the system joint thoroughly.

Note: at a bilateral orthosis, only check one system joint at a time.

Disassemble the system joint completely. Clean all component parts and check them carefully.
