Each wheelchair user has their own ideas regarding the wheelchair type and accessories that are
correct for him / her, as well as the position in the wheelchair and the handling characteristics.
Therefore, the Start wheelchair offers many options that permit the wheelchair to be adapted
according to your requirements. We recommend consulting your dealer or therapist to determine
the correct wheelchair settings for you.
6.1 Adjusting the seat height and seat inclination (Fig� 45/46)
The higher you attach the rear wheel to the frame, the more the seat inclines downward. This
has two effects:
• First, the wheelchair has a greater tendency to tilt backwards.
• Secondly, the user sits deeper in the wheelchair and thus has more stability.
A careful and synchronized height adjustment of both the rear wheels and the casters will allow
to adapt the seat height to the user's individual requirements.
Start M1 Intro, M2 Effect, M3 Hemi and M6 Junior: These versions offer the possibility to change
the vertical position of the rear wheel by shifting the rear wheel adapter along the frame. Loosen
the two screw connections (Fig. 45, item A) and remove the screws. Move the adapter to the
desired position and firmly retighten the screws.
For fine adjustment, loosen the nut of the fitting on the inside of the rear wheel adapter (Fig. 45,
item B) and move the fitting along the slot hole. The setting must always be equal on both sides.
Start M4 XXL and M5 Comfort: Loosen the 4 screw connections which connect the rear wheel
adapter to the central unit (Fig. 46). The rear wheel adapter can then be shifted up or down.
The setting must always be equal on both sides.
INFORMATION
When the rear wheel position is changed, the angle of the caster axle in relation to the ground also
changes. Ensure that this angle is always approx. 90° wide (see Section 6.4). The wheel lock must be
re-adjusted as well (see Section 6.5).
INFORMATION
Make sure to firmly retighten all screws and nuts after making adjustments. The proper torque for the
screw connections of the rear wheel adapter is 10 Nm for screw connection A, 50 Nm for screw con-
nection B of the fitting, and 8 Nm for screw connection C (see Fig. 45/46).
