3. Angle of the steering wheel axle
By changing the height of the driving wheel or front wheel, the angle
of the steering wheel axle can also be altered. However, this should
always be at the correct angle (90°) to the floor (see Fig. 19). First,
loosen the locking mechanism by loosening both screws on the inside
(see Fig. 20). Move the front wheel to the required position and then
tighten the fixing screws up again.

4. Adjusting the parking brake
When the driving wheel height is changed, the knee lever
brake must be readjusted (see 4.6).

4.4.2 Seat angle

If you incline the seat of the wheelchair backwards, this means you are
20
seated more deeply and firmly in the chair. To lean the seat backwards,
you have to move the floating axle to a higher position. If you want to
incline the seat forwards, fix the floating axle in a lower position. The
floating axle is fixed in the same way as in 4.8.

4.5. Wheelbase

Caution, risk of tipping! If you move the driving
wheel forwards or the backrest backwards, this
significantly increases the risk of tipping. Anti-tip
wheels or an extended wheelbase are then necessary.
Check the settings first with a helper. Only
use settings that you feel safe with.
Extending the wheelbase increases the stability and equilibrium of
the wheelchair. On the other hand, if the wheelbase is reduced, this
then improves manoeuvrability. A reduction of the wheelbase is only
advisable for practised drivers. To adjust the wheelbase, loosen the
wheel suspension, which is fixed with two screws and then attach
it again the other way round. Make sure that all screws are firmly
tightened.
When the wheelbase is changed, it is absolutely
essential to adjust the parking brake afterwards!
