Adjustment/assembly instructions
6.3 Adjusting the rear wheel in the rear wheel adapter (Fig. 44/45)
Each change of position of the quick-release axle housing in the rear wheel adapter has an in-
fluence on the posterior seat height and the centre of gravity! The relation between anterior and
posterior seat height represents the individual seat inclination. The higher you attach the rear
wheel in the rear wheel adapter, the more the seat pitches down. This has two effects:
1. The wheelchair has a greater tendency to tilt backwards.
2. The user sits deeper in the wheelchair and thus has more stability.
6.3.1 Adjustment in the rear wheel adapter (Fig. 44/45)
Loosen and remove the nut (Fig. 44, item A) of the rear wheel fitting (Fig. 44, item B) on the in-
side of the frame. The possible positions are determined by defined bore holes in the rear wheel
adapter (Fig. 45, item C).

6.4 Adjusting the caster wheel journal angle (Fig. 46/47)
After the rear wheels have been mounted in the appropriate position, the caster wheel journal
angle must be readjusted. The caster adapter should be as horizontal as possible in relation to
the ground to ensure optimal driving behaviour of the wheelchair. The caster adapter allows for
continuous angle adjustment.
