5.2 Optional: Installing the foam cover
The foam cover sits between the prosthetic socket and prosthetic foot. It is
cut longer in order to compensate for the movements of the prosthetic foot
and prosthetic knee joint. During flexion of the prosthetic knee joint, the foam
cover undergoes posterior compression and anterior elongation. The foam
cover should be stretched as little as possible in order to increase its service
life. There is a connecting element (such as a connection plate, connection
cap or connection cover) on the prosthetic foot.
Required materials: degreasing cleaner (e.g. 634A58 isopropyl alco­
>
hol), 636N9 contact adhesive or 636W17 plastic adhesive
1) Measure the length of the foam cover on the prosthesis and add the
length allowance.
TT prostheses: Distal allowance for movement of the prosthetic foot.
TF prostheses: Allowance proximal of the knee rotation point for flexion
of the prosthetic knee joint and distal allowance for movement of the
prosthetic foot.
2) Cut the pre-shaped foam cover to length and fit it in the proximal area on
the prosthetic socket.
3) Pull the foam cover over the prosthesis.
4) Set the connecting element onto the footshell or prosthetic foot. Depend­
ing on the version, the connecting element engages in the edge or rests
on the foot adapter.
5) Install the prosthetic foot on the prosthesis.
6) Mark the outer contour of the connecting element on the distal face of
the foam cover.
7) Disassemble the prosthetic foot and remove the connecting element.
8) Clean the connecting element using a degreasing cleaner.
9) Glue the connecting element onto the distal face of the foam cover
according to the marked outer contour.
10) Let the glue dry (approx. 10 minutes).
11) Install the prosthetic foot and adapt the exterior cosmetic shape. Take
into account compression caused by cosmetic stockings or SuperSkin.
6 Cleaning
1) Clean the product with a damp, soft cloth.
2) Dry the product with a soft cloth.
3) Allow to air dry in order to remove residual moisture.
