Mounting The Socket Adapter; Donning The Prosthesis - Ottobock 4R220 Instrucciones De Uso

18) NOTICE! Do not allow the duckbill valve to come into contact with
grease.
Insert the duckbill valve into the valve bushing with the pointed end first
(see fig. 30).
19) Screw the valve bushing into the prosthetic socket (torque value: 3 Nm).
20) Insert the piston into the cylinder to the stop (see fig. 31).
21) Insert the stop ring into the thread of the cylinder and tighten it with the
mounting wrench (see fig. 32).

5.4 Mounting the socket adapter

The connection to the distal prosthetic components is established by a sock­
et adapter. A spacer plate is positioned on the snap bushings in the distal
end of the socket when mounting the socket adapter. To ensure forces are
transferred to the Dynamic Vacuum System, the spacer plate must not lie
against the laminate.
Required tools and materials:
>
710D4 torque wrench, 636K13 Loctite®, spacer plate, 501S128=M6x22
or 501S128=M6x25 countersunk head screws
1) Set the spacer plate onto the prosthetic socket (see fig. 33).
2) If the pyramid receiver or the pyramid adapter is rotatable: Place
the pressure plate on the adapter.
3) Apply the adapter to the prosthetic socket (see fig. 34).
4) Optional: Align the pyramid receiver or the pyramid adapter.
5) NOTICE! Only use the screws specified here.
Select suitable countersunk head screws.
Fixed pyramid adapter/pyramid receiver: 501S128=M6x22
Swivelling pyramid adapter/pyramid receiver: 501S128=M6x25
6) Secure the screws with Loctite®.
7) Screw in the 2 posterior countersunk head screws and tighten them
(torque value: 12 Nm).
8) Screw in the 2 anterior countersunk head screws and tighten them
(torque value: 12 Nm).
6 Use

6.1 Donning the prosthesis

1) Apply the liner to the residual limb so that the distal end is aligned with
the longitudinal axis of the residual limb. Unroll the liner onto the residual
limb so that it has no wrinkles, without shifting the soft tissue.
