► To reduce friction and to eliminate noise, apply 519L5 Silicone Spray directly onto the contact
surfaces of the cosmetic foam cover.
► After fabricating the cosmetic cover, repeat the dynamic trial fitting since the cover affects the
adjustments of the prosthesis (e.g. damping).
5.3 Bench Alignment
+ = anterior placement / – = posterior placement (in relation to the alignment reference line)
No. see fig. 4
Required equipment:
Alignment apparatus (e.g., 743L200 L.A.S.A.R. Assembly or 743A200 PROS.A. Assembly)
Position the prosthetic foot in the alignment apparatus in accordance with the following values:
a–p positioning, middle of the prosthetic foot to the alignment reference line
+30 mm
Heel height (see section "Determining the Effective Heel Height" – see Page 25):
effective heel height (x) + 5 mm
External foot rotation:
approx. 5°
Check the prosthetic knee joint according to the section "Checking the Factory Settings" (see
Page 27).
Position the alignment reference point
ment apparatus according to the following values:
Height of the alignment reference point in the alignment apparatus:
MTP-floor measurement + 20 mm
a–p positioning of the alignment reference point to the alignment reference line:
0 mm
External rotation of the prosthetic knee joint:
approx. 5°
INFORMATION: If the length-adjustable 2R45=34 Tube Adapter (max. body weight 125 kg)
is used in the alignment of the test prosthesis, the required length for the definitive pros­
thesis is easier to determine.
When using the included tube adapter, note the section "Adapting the Length of the Tube
Adapter" (see Page 25).
Connect the prosthetic knee joint to the prosthetic foot and chosen adapters according to their
instructions for use and the section "Installing the Tube Adapter" (see Page 25).
Mark the socket reference point and tuberosity reference point on the prosthetic socket according
to the section "Determining the Socket Reference Point" (see Page 26).
Position the tuberosity reference point
floor measurement.
CAUTION! The correct position and flexion of the prosthetic socket is crucial for the
safety of the patient and functionality of the prosthetic knee joint, and avoids premature
wear.
INFORMATION: The 4R118 Adapter Plate (max. body weight 125 kg) can be used for fur­
ther posterior placement.
Position the prosthetic socket so the socket reference point
.
Set the determined socket flexion angle β (see section "Determining Socket Flexion" – see
Page 26).
Position the lamination anchor or socket adapter so that all prosthetic components between the
socket and prosthetic knee joint can be connected to each other correctly.
Join the prosthetic socket and the prosthetic knee joint using the adapters you selected.
Be sure to follow the adapter instructions for use during adjustment and installation.
