2. Front wheel height
The height of the front wheels can be adjusted to three levels. Loosen
the Allen bolt (fig. 21) and pull out the wheel axle. Move the front
wheel to the desired height, then tighten the bolt again.
3. Angle of the steering wheel axle
The angle of the steering wheel axle can change as a result of changing
the height of the drive wheel and/or the front wheel. This should,
however, always be at right angles (90°) to the floor (fig. 22).
First loosen the locking device by loosening both Allen bolts on the
interior side (fig. 23).
You can then adjust the angle with the aid of the two grub screws
(fig. 24). Subsequently both attachment bolts on the inside are to be
tightened up.
4. Adjusting the parking brake
With any change to the height of the drive wheel, the parking brake
has to be newly adjusted (see 4.7).
4.5.3 Seat Angle
If you incline the seat of the wheelchair towards the back, you will be
sitting more deeply and firmly in the chair. To incline the seat towards
the back, attach the quick-release axle in a higher position. If you wish
to incline the seat towards the front, fix the quick-release axle in a
lower position. Fixing the quick-release axle is done in the same way
as in 4.5.2.1.

4.6. Wheel base
Caution. Danger of tipping! If you adjust the
driving wheel forwards or the backrest backwards,
the danger of tipping is increased significantly.
Anti-tip wheels or a wheelbase extension are
necessary. Check the settings first with a
helper. Only use settings that you feel safe with.
The stability of the wheelchair is improved by lengthening the
wheel base. On the other hand, shortening the wheel base improves
manoeuverability. A shortening of the wheelbase is only recommended
for practised wheelchair users.
To set the wheelbase, loosen the four fastening screws that secure the
wheel attachment.
The wheelbase can be adjusted in four stages. Fasten the wheel
attachment afterwards in the cut-outs provided. Ensure that all four
screws are securely tightened. To increase the wheelbase, a wheelbase
extension can also be used.
When changing the wheel base, a subsequent
adjustment of the parking brake is also absolutely
necessary!
