6.1.1 Instructions of Use - Headless Screws (A1 and A2 only)
By using the adjusting screws M28-12 or M28-16, static corrections are possible at any
time. If a module has to be replaced or removed the previously adjusted position is
maintained if only two adjacent adjusting screws (not opposite), the ones screwed in
at the deepest, are removed.
If the adjusting screws are, too long (damage of the foam cover) or too short
(reduced stability) these have to be replaced with appropriate ones.
Use a toque wrench to tighten the adjusting screws.
Tightening torque: 12 Nm.
Secure the various screws, used for assembly, with Loctite 222.
6.2 A30 Reducation Adapter

the distal attachment of a JT09, JT20, JT20S, JT22 or JT22S (Uniprox knee joints) as
far as possible.
The clamp adapter is aligned distally/dorsally and screwed to the respective tube
clamp adapter of the modular knee. Use the torque wrench provided.
The distally aligned 30 mm tube attachment accepts a 30 mm modular tube adapter.
Tightening torque: 8 Nm
