•
Do not longer use the knee joint if its function is impaired. This may be due to
stiffness, restricted extension, noise generation, faulty swing phase control or
stance phase safety, as well as impact from an external force (for example, if
dropped). In such cases, it must be checked by a professional and, if necessary,
sent to Uniprox GmbH & Co. KG.
•
There is a risk of jamming when the joint is in use.
•
The product must not be changed or applied in any improper way. Non-compliance
can impair the function of the product and thus no liability will be accepted.
•
The safety of the user is not guaranteed if the product is not used for its intended
purpose. This will also terminate the warranty of the product.
•
Joint components may heat up slightly during walking.
•
Silicone spray should be used to prevent noises being generated by contact
between the cosmetic foam and knee joint. Do not use Talcum powder as it removes
lubricant from the bearings and may lead to impaired function as a result.
6. Construction and assembly instructions
JT05 and JT09:
The starting point for a correct structure is the
determination the individual load line and the
transfer of forces to the components of the
prosthesis according to the assembly guidelines
shown (see graphic). The knee axis is 15 mm behind
the assembly reference line and the foot part in
the middle third of the foot.
JT09:
The 34 mm tube clamp of the JT09 must be secured
with Loctite® 222 and tightened with a 4 mm hex wrench.
The torque is 6 Nm

Adjustment of Swing and Stand Phase
The modular stance control knee joint is delivered with optimal setting. Stance and
swing phase can be controlled by adjusting the extension assist, the friction and the
weight controlled locking mechanism.
Strictly follow the instructions below before changing the preset
adjustments.
6.1 Setting the swing phase control of the feeder
JT05:
Adjust the tension of the advancing springs by turning the setscrew.
•
Use a 4 mm allen key.
•
Turn to the right: increase tension
•
Turning to the left: decrease tension
Please notice that the linkage has to be mounted correctly.
JT09:
The tension of the integrated spring feeder can be adjusted by turning the
adjusting wheel.
•
Turn to the right: decrease flexion resistance
•
Turn to the left: increase flexion resistance
