LIMITATIONS
The Seattle LightFoot² with Titanium Pyramid cannot be used with R.O.L rotators or other devices that require modication of
the keel.
INSTALLATION AND USE
Recommended installation and use procedures must be followed for maximum safety and service life.
The Seattle LightFoot² with Titanium Pyramid comes pre-assembled with a Trulife spacer, foot pyramid and foot bolt. Before
installation, check the bolt for loosening, ensuring that the bolt is set to a torque value of 27 Nm (20 ft-lbs or 240 in-lbs).
Warning: Never modify the keel. It will void the warranty and can cause bolt or keel failure. If you must alter the form of
the foot, be sure not to grind on the keel.
Warning: Never re-drill the mounting hole.
Warning: Never modify the spacer. It will void the warranty and may cause failure.
Warning: Use only bolts supplied by Trulife. Use of unapproved bolts will void the warranty and can cause bolt failure.
Endoskeletal Installations
When using the Seattle LightFoot² with Titanium Pyramid with a Seattle Endoskeletal Cosmesis, remove the foot from the
endoskeletal limb. Completely rough the mounting surface of the foot and cosmesis. Remove all foam particles from the abraded
surfaces. If desired, apply small reference marks to the mounting surfaces to facilitate careful matching of the surfaces. Apply a
thin layer of contact cement to each surface and allow it to dry. Apply a second layer of contact cement and allow to dry. Match
the two surfaces carefully and press them together tightly both on the outside and inside of the seam.
Color Coating
Before applying color coating to the foot, remove any remaining mold release from the cosmesis with naphtha. Naphtha is
recommended to improve the adhesion of color coating, but alcohol can be used as well.
ALIGNMENT
The recommendations in this guide provide reliable starting points for static alignment of the Seattle LightFoot² with Titanium
Pyramid. Since each patient is unique, nal alignment may require additional adjustment.
