Runway® HX Instruction for Use
Product Number: RS2-K1
Rubber stiffening bumpers are included to adjust the heel stiffness during loading
response. The bumpers may be temporarily attached between the heel lever and the keel
using the pre-applied adhesive in the location indicated on the bumper package to increase
heel stiffness one category. If the heel stiffness is too stiff, move the bumper posteriorly;
too soft, move it anteriorly. For permanent placement, clean off the pre-applied adhesive
with Acetone, and adhere bumpers using Super Glue (cyanoacrylate).
Replace Spectra™ socks at intervals appropriate to the user's activity level to protect the
foot shell and minimize noise. Failure to inspect and replace the Spectra™ socks may
prematurely wear the foot module.
Use the Foot Shell Removal Tool (ACC-00-10300-00) to install or remove the foot shell to
prevent damage to the foot module.
Maximum user weight: 116 kg
Available sizes: 22cm-28cm
Heel height: Adjustable, 0-5cm
• Insert a 4mm hex key (provided) through the posterior foot shell into the ankle
mechanism.
• To increase the foot height, turn the hex key clockwise.
• To decrease the foot height, turn the hex key counterclockwise.
• Remove the hex key prior to allowing ambulation.
• Your prosthetist may let you use the prosthesis without a foot shell for a short period
of time, allowing you to visually learn to adjust the ankle mechanism by setting the
pylon in the correct vertical orientation.
• Inform your prosthetist if the toe and heel of the foot do not feel balanced.
• For best result, be seated in a chair to adjust the heel height.
• Do not attempt to adjust the ankle while standing without using a grab rail or other
appropriate fixed object for support.
• Insert a 4mm hex key (provided) into the back of the foot shell.
• To increase the foot height, turn the hex key clockwise.
• To decrease the foot height, turn the hex key counterclockwise.
• Fourteen turns will change the heel height by one inch.
• The wrench must be removed from the ankle before placing weight on the foot.
The ankle mechanism requires periodic maintenance.
Inspect the foot every six months. For an active user, increased inspection frequency

may be needed. Service as necessary. Replace Spectra™ sock and/or foot shell if
worn to prevent damage to the foot module components.
Wet or dirty environments may cause the ankle module to malfunction and make it

difficult to operate.
o If the ankle module is exposed to wet or dirty environments, it is
recommended to periodically clean and lubricate the module in order to
minimize impact on module performance.
Disassemble from shell, rinse with fresh water and thoroughly dry.

If corrosion or buildup has occurred, clean the ankle mechanism with

solvent (i.e., acetone, WD-40) and compressed air.
Cycle the mechanism thru the entire range while cleaning.

Lubricate the slide with light grease, or spray lubricant and wipe off

excess.
If the ankle mechanism makes a clicking noise when tapping the toe or heel of the foot,

ankle shims adjustment will be required by the prosthetist.
