5.5.1 Checking the Factory Settings
Function
Flexion damping
Extension damping
Tools required:
>

1) Check whether the settings match the factory settings (see table).
2) In case of deviations, restore the factory settings using the adjustment wrench.
5.5.2 Setting Flexion Damping
Function
Flexion damping
Tools required:
>
710H10=2x3 Adjustment Wrench
► CAUTION! The prosthetic foot must not swing through too far.
Adjust flexion damping using the adjustment wrench so that the prosthetic foot swings
through sufficiently according to the needs of the patient.
5.5.3 Setting Extension Damping
Function
Extension damping
Tools required:
>
710H10=2x3 Adjustment Wrench
► CAUTION! The prosthetic knee joint has to reach full extension, even at slow walking
speeds. If the 513D83=1.1X12.9X66 Compression Spring, weak is installed and the
extension assist effect is not sufficient for the patient, the strong compression spring
has to be installed again (section "Installing the compression spring" – ).
Using the adjustment wrench, adjust extension damping so that the prosthetic knee joint does
not swing too hard against the extension stop.
5.5.4 Optional: Replacing the Compression Spring
If required, the installed strong compression spring can be replaced with the weak compression
spring or omitted entirely (see the section "Scope of Delivery" – see Page 23). To prevent injur­
ies due to falling, this is only permitted if the patient is able to bring the prosthetic knee joint to
full extension prior to heel strike in all situations.
To prevent damage to the product, the centring disc
knee joint using suitable pliers (see fig. 6) if the compression spring is omitted entirely.
Tools required:
>
Flat screwdriver
1) Keep the prosthetic knee joint vertical during assembly and disassembly (see fig. 6).
2) Insert the flat screwdriver
