9) Sand the distal end of the socket down to the heads of the cap
screws (see fig. 28).
10) Remove the cap screws.
11) Sand the distal end of the socket flat and check that its surface is
even.
12) Remove any dirt from the 4 openings in the distal end of the sock­
et. This ensures that the snap bushings will lie flat against the cyl­
inder body.
13) INFORMATION: The snap bushings must protrude approx.
1 mm from the laminate. This ensures forces are transferred
to the Dynamic Vacuum System.
Apply silicone bonding agent to the snap bushings and insert
them into the openings with the groove end first (see fig. 29).
14) Unscrew the valve dummy.
15) Remove the piston dummy and silicone dummy from the prosthet­
ic socket.
16) Wipe out the cylinder space with a lint-free cloth.
17) Grease the cylinder space and O-rings of the valve bushing with
the supplied Polylub GLY 801.
18) NOTICE! Do not allow the duckbill valve to come into con­
tact 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 fixation ring into the thread of the cylinder and tighten it
with the mounting wrench (see fig. 32).
5.4 Fastening the socket adapter
The connection to the distal prosthetic components is established by a
socket 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
CAUTION
Using the product without a sealing sleeve
Risk of injury due to unexpected loosening of the connection
►
Always use the product with a sealing sleeve so that a vacuum
can be generated.
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.
2) Slide into the prosthetic socket with the liner. The magnets in the
piston of the Dynamic Vacuum System connect to the metallic
counter-piece in the liner.
