INSTALLATION AND USE
The Solas is shipped with a Spectra sock pre-assembled into a foot shell.
Failure to follow the installation and use procedures may lead to structural failure of the
components, subjecting the user to risk of serious personal injury.
Bench Alignment
Bisect the medial side of the socket and drop a plumb line. This line should fall between
12–14 mm (1⁄2”) anterior to the center axis of the pylon.
Bisect the posterior side of the socket and drop a plumb line. This line should bisect the
center axis of the pylon or pass through the heel.
Dynamic Alignment Suggestions
In order to achieve more heel compression, move the socket slightly posterior to the
recommended bench alignment.
Toe Wedge Options
In order to increase dorsiflexion resistance and mid-stance stability Toe Wedges are
provided. Simply insert the desired Toe Wedge between the shank and keel as shown and tack
with a drop of instant adhesive (super glue). Secure with additional adhesive if the evaluation is successful.
Finalize Foot and Cosmetic Cover
Follow assembly instructions and recommended fastener tightening torque of the mating modular adapter.
AAA adapter set screw torque setting is 15-18 Nm (11-13 ft-lbs).
MAINTENANCE GUIDELINES
Foot assembly should be inspected after first 30 days of use.
Inspect entire prosthesis for wear during normal consultations.
Foot shell may require replacement if wear is excessive.
Check screws periodically for loosening.
Looseness in any screw may cause failure.
Check the pyramid bolt and the three keel bolts during each visit to verify correct torque setting:
o
Pyramid bolt = 88 Nm (65 ft-lbs)
Use 7/16”, 12-point socket
o
Keel bolts = 20Nm (15 ft-lbs )
Use 8mm socket
