Note
:
Adjustments of as little as 15 to 20° turn provide a perceptible change. Settings which are too
loose may cause noise and lead to premature wear. Those which are too tight will cause the brake to be
activated even when not under load
Set screw (5) rotation:
Clockwise - increases brake sensitivity/swing friction
between the Knee Axis (2) and Brake
Bushing (3)
Counter-clockwise - decreases brake sensitivity/swing friction
between the Knee Axis (2) and
Brake Bushing (3)
Set Screw (5) 3mm hex head

Set screw (11) rotation:
Clockwise rotation: braking is less responsive = requires more weight input
Counterclockwise rotation: braking is more responsive = requires less weight input
The knee joint functions well only when the pneumatic extension adjustment, brake sensitivity/swing friction
and brake effect are cohesively adjusted. Take care in making individual adjustments, and reassess function
in the parallel bars.
Important! Do not use talcum powder! Talcum powder reduces the lubrication of the mechanical parts,
which may lead to a malfunction and thus increase the risk of failure. Using this medical product after
application of talcum powder will render all claims against ST&G null and void.
Important! Please Note: The pneumatic extension adjustments, brake friction sensitivity adjustments,
and weight activation adjustment function of the knee joint, must be coordinated together. Take care
when making individual adjustments, as those adjustments should be assessed, and reassessed
should more adjustments be warranted to verify function.
5.2 Adjusting the Stance Phase Control (Fig. 5)
The responsiveness of the brake effect may be regulated by the stance control adjustment Set Screw (11). Use
a 6 mm hex head wrench.
