Lock the elbow joint with cable lock.
Loosen the screw on the band clamp.
Shorten or lengthen the band.
Tighten the screw on the band clamp.
Remove the fixation fork to free the band
cam.
To decrease preflexion = lengthen the
band
To increase preflexion = shorten the band
A 3 mm change in the length of the band
causes a 5° change in the flexion angle.
Make sure that the forearm swings freely
and that the band cam is still fastened to the
extension stop with the fixation fork.
The preflexion angle is initially set at about
10 degrees.
Changing the band length also affects the
free swing range.
When the preflexion angle is increased 10°
by tightening the band, the forearm will enter
the second compensation range 10° later
in flexion as well.
