Maintenance NEURO SWING H₂O

Step 1/11

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

Step 2/11

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.

Step 3/11

Demount the spring units in order to examine it. Check if the system joint moves without lateral play.

Step 4/11

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

Step 5/11

Hold the tibial 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.

Step 6/11

-  damaged sliding washer
-  worn out bearing nut
-  worn out sliding bushing
-  worn out screw

Replace component parts if they are worn out.

Step 7/11

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

Step 8/11

Replace the sliding bushing if it is worn out.

Step 9/11

Replace the spring unit in case of loud noise generation and/or a reduced spring force or a limited range of motion. 

Step 10/11

Check the spring unit’s O-ring. Replace the O-ring if it is worn out.

Step 11/11

Note the online tutorial for the joint assembly of the carbon system ankle joints in order to reassemble the system joint.
