8 Use
8.1 Putting on the liner and socket
Putting on the liner
1) Check the liner and magnetic cap for damage.
2) Turn the liner inside out and apply it to the end of the residual limb.
3) Apply the liner to the end of the residual limb and check the alignment of the liner at the same
time.
INFORMATION: The orientation thread on the inner side of the liner has to be centred
on the front of the transfemoral residual limb. The liner's two seams have to be posi
tioned on the sides of the transfemoral residual limb.
4) Unroll the liner onto the residual limb so that it has no wrinkles or air pockets, without shifting
the soft tissue.
5) Check the fit and the alignment of the liner.
6) In a standing position (or position with the residual limb nearly extended), unroll the liner part-
way and roll it back up again to release possible skin tension.
Putting on the socket
1) To open, pull the Boa dials away from the prosthetic socket.
2) Open the socket by pulling the shells apart.
3) Sit on the front edge of a chair.
4) Pull the socket over the residual limb.
INFORMATION: In doing so, note the alignment of the toes and the position of the
lower leg so the desired level of exterior foot rotation is given while standing and
walking. If the exterior foot rotation is not correct, take the socket off again (at least,
the magnetic cap has to be released from the bottom of the socket) and put it back on
in a changed position.
→ The magnetic bottom shell of the socket and the magnetic cap of the liner attract each oth
er when they are brought close together. A clicking sound is heard, indicating the proper
connection of the socket and liner.
5) Push the Boa dials towards the socket.
6) Turn the Boa dials clockwise.
→ The Boa cables are tightened and the socket is closed.
INFORMATION: Position the outer socket shell (lateral) under the inner socket
shell (medial).
7) Tighten the Boa dials as needed.
8.2 Taking off the socket and liner
1) Pull the Boa dials away from the socket.
2) Pull the outer socket shell (lateral) to the outside.
If plastic adhesive strips are used in the lateral socket shell, pull until there is no longer any
contact between the plastic adhesive strips and textile cover of the liner.
3) Push the socket off the residual limb.
In doing so, preferably grasp the socket brim of the lateral socket shell with one hand and the
socket brim of the medial socket shell with the other hand.
4) Unroll and remove the liner from the residual limb.
9 Cleaning
1) Clean the product with a damp cloth and mild soap (e.g. Ottobock 453H10=1 Derma Clean)
when needed.
2) Dry the product with a lint-free cloth and allow it to air dry fully.
