►
Use the adjustment wrench to adapt the stance phase damping threshold to the needs of the
patient.
5.5.7 Optional: Installing the Compression Spring
The additional compression spring is installed in the lower joint section if the patient needs more
support in order to bring the prosthetic knee joint to full extension.
>
Required tools and materials:
Torque wrench (2Nm), 513D59=1.3X8.8X86 Compression Spring
1) Unscrew the spring retainer from the lower joint section (see fig.17).
2) Insert the compression spring into the larger compression spring in the lower joint section
(see fig.18).
3) Screw the spring retainer into the lower joint section (installation torque: 2Nm).
4) Check the settings of the prosthetic knee joint and reaching extension with a walking test.
5.5.8 Closing the Covers
1) Close the extension damping and flexion damping covers (see fig.19).
2) Close the stance phase damping cover (see fig.20).
5.6 Finishing the Prosthesis
>
Required tools:
Torque wrench
1) Tighten all screws of the prosthetic components to the specified installation torque values.
2) Verify proper functioning of the prosthesis.

6.1 Information for use
CAUTION
Overheating of the hydraulics due to excessive strain
Burns, injuries caused by falling due to changes in functionality and damage to prosthetic com
ponents
►
Do not touch overheated prosthetic components.
►
Reduce all activities if there are changes in functionality, in order to allow the overheated
prosthetic components to cool down.
►
If overheating or changes in functionality occur, have the prosthesis checked by authorised
qualified personnel.
CAUTION
Use in wet areas
Fall due to slipping or altered functioning of the prosthetic knee joint
►
Before using the prosthesis in wet areas, lock the prosthetic knee joint (see section "Lock
ing the Prosthetic Knee Joint" – see Page30).
►
Adjust the walking speed to the local conditions.
►
On wet surfaces, only use prosthetic feet with a non-slip sole.
