→ Increase threshold – Joint brakes at a higher load
Reduce threshold – Joint brakes at a lower load

► Increase gradually (rotation: approx. 45° – 90°).
► When the desired effect is reached, continue with "Setting axis
friction".

Setting axis friction ( on page 7)
► Set the axis friction as shown in the illustration.
→ Decrease play – Increase resistance to motion
Increase play – Decrease resistance to motion
→
► Reduce play and increase resistance to motion gradually (rota­
tion: approx. 20°).
► Set the load-related braking action and axis friction so that the
prosthetic knee joint switches from the stance phase to the swing
phase and no longer jams.
► NOTICE! To prevent increased wear and tear, do not use axis fric­
tion to control the swing phase.
Setting the extension assist (
► Set the extension assist as shown in the illustration if necessary.
Increase spring tension
→
→ Reduce spring tension
► CAUTION! Set the extension assist so that the lower leg of the
prosthesis swings through in the dorsal direction according to the
patient's requirements, but reaches full extension in time before
the next heel strike.
Fine-tuning the settings
► CAUTION! The various settings of the prosthetic knee joint can­
not be adjusted entirely independently of each other. When the
settings cannot be fully adjusted to the comfort needs of the
patient, the settings should be established primarily based on
safety aspects.
► Adapt the settings of the prosthetic knee joint to the patient by
means of fine-tuning and exercises.

► If the extension position is not reached with every step and at any
walking speed, reduce the braking effect and/or increase the ini­
tial tension of the extension assist.
► Check the adjustment of the prosthesis settings during normal
consultations and the annual safety inspection.
Advise the patient to check the prosthesis if changes in function
occur.
7.5 Finishing the prosthesis
Put on protective cover
► When the prosthesis is finished, put on the protective cover as
shown in the illustration
: Alternative positioning
: Recommended positioning
► CAUTION! To avoid product damage and the risk of falling, finish
the prosthesis by replacing set screws that are too short or too
long, and by tightening all screw connections. In doing so, note
the instructions for use for all prosthesis components regarding
torque values and thread lock.
7.5.1 Attaching the cosmetic cover
CAUTION
Use of talcum
Risk of injury, damage to the product due to lack of lubrication
► Do not use talcum on the product or other prosthesis compon­
ents.
Recommended combinations
Foam cover
► After affixing the cosmetic elements, verify proper functioning of
the prosthesis.
► To reduce friction and to eliminate noise, apply silicone spray dir­
ectly onto the contact surfaces of the cosmetic foam cover.
