→ During installation the whole camber module must be fully enclosed by the axle tube clamp.
→ Check the position by measuring it afterwards.
4) Lightly clamp the camber module in the axle tube clamp.
5) Adjust the track width in the same fashion on the other side. Make sure that both camber modules have been
adjusted symmetrically.
6) Adjust the track (see Page 31). Use an adjustment aid (e.g. back square) to do so.
7) Tighten the Allen head screw respectively on the axle tube clamps to 15 Nm (see Fig. 78).
8) Tighten the Allen head screw respectively on the seat clamps to 7 Nm (see Fig. 77).

3.10.5.6 Adjusting the Track

INFORMATION
► The track must be adjusted after the following adjustments have been made:
→ Adjusting the track width: see Page 29
→ Adjusting the rear wheel camber: see Page 30
► The track setting must be checked and, if necessary, adjusted after the following adjustments have been
made:
→ Adjusting the horizontal position of the rear wheel: see Page 28
INFORMATION
► When adjusting the rear wheel track, always check the symmetry of the track width setting. To do this, meas­
ure the distance between the outer side of the camber module and the outer side of the axle tube clamp.
► The caster wheel journal angle should be checked immediately after every adjustment to the track ( et seq.).
1) Loosen the seat clamps (see Fig. 77) and axle tube clamps (see Fig. 78) so that the camber modules are only
lightly clamped in the rear wheel axle (see Page 29).
2) Place the wheelchair on an even surface. Avoid twisting the axle when doing this.
3) Pull the rear wheel out slightly in order to make room for the installation.
4) A 90° back square placed on a level surface is used as an adjustment aid.
5) Carefully turn the camber module until the spanner flat is flush with the blade of the back square. The spanner
flat of the camber module is now vertical (see Fig. 76, item 2).
6) Tighten the Allen head screws respectively on the axle tube clamps to 15 Nm (see Fig. 78).
7) Tighten the Allen head screws respectively on the seat clamps to 7 Nm (see Fig. 77).
