After successful optimisation, the trial prosthesis is converted to the definit­
ive prosthesis by replacing the test foot adapter with the sport foot adapter.
Further information is found in the instructions for use for the prosthetic foot
and foot adapter.
5.3.1 Adjusting Flexion and Extension Damping
Valve
Flexion valve
Extension valve
Required tools and materials:
>
710H10=2x3 Adjustment Wrench
1) Use the adjustment wrench to adapt the flexion resistance to the needs
of the patient.
2) Use the adjustment wrench to adapt the extension resistance to the
needs of the patient.
3) Check the adjustments in dynamic trial fitting and correct as required
according to the table below.
Situation
Lower leg swings through
too far
Lower leg does not swing
through sufficiently
Lower leg impact too hard
on the extension stop
Lower leg does not reach
full extension before heel
strike
6 Use
CAUTION
Overheating of the hydraulics due to excessive strain
Burns, injuries caused by falling due to changes in functionality and dam­
age to prosthesis components
► Do not touch overheated prosthesis components.
► In case of changes in functionality, stop all activities and allow the over­
heated prosthesis components to cool down.
► In case of changes in functionality, reduce strain on the prosthesis
component in order to allow cooling.
