Height of the front wheel
The front wheel can be adjusted to three heights. Undo the hexagon
lock nut (Fig. 18) and pull out the wheel axle. Mount the front wheel at
the required height and re-tighten the lock nut.
In addition the castor bearing bracket can be rotated to achieve even
greater adjustment.

Angle of the steering wheel axle
By changing the height of the drive wheel or front wheel, the angle of
the steering wheel axle may change. However this should always be at
right angles (90°) to the floor (Fig. 19).
First undo the lock by loosening the two Allen screws on the inner side
(Fig. 20). You can then adjust the angle using the two setscrews on the
under side (Fig. 20).
Then re-tighten the two fixing screws on the inner side.

4.8. Wheelbase
Attention: risk of tipping over! If you move the drive
wheel forwards or the backrest backwards, then the
risk of tipping over increases significantly. Anti-tip
wheels or a wheelbase extension are required. Check
the settings first with an assistant. Only use settings
which you consider to be safe.
The wheelchair's stability and steadiness is improved by extending the
wheelbase.
Conversely, if the wheelbase is reduced, the manoeuvrability is improved.
Reducing the wheelbase is only recommended for experienced riders.
To adjust the wheelbase, undo the four fixing screws which fix the
wheel support (Fig. 21). The wheelbase can adjusted in four positions.
Then refit the wheel support in the recesses provided for this purpose.
Make sure that all screws are firmly tightened.
If the wheelbase is changed, then it is essential to
adjust the knee lever brake as well!
