ties are parallel before re-tightening the screws.
INFORMATION: During the adjustment process, never loosen the screws (see Fig.19, Fig. 1 and Fig. 3)
at the same time.
4) Tighten the Allen head screws to 10Nm. In doing so, ensure that the clamp washer is parallel (not tilted) in the
cross-tie for optimum fixation.
INFORMATION: After each adjustment of the lower leg length, readjust the footrest angle.
