2. Height of the front wheel
• First, remove the masking on the optional drill holes.
• Loosen the axle (Allen key, SW 4) and take it out com-
pletely.
• Place the steering wheel in the right position for the
required seat height.
• Reinsert the axle into the steering fork and tighten it up
again.
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 knee lever brake
When the driving wheel height is changed, the knee lever
brake must be readjusted (see 7.6).
7.4.2 Seat angle
If you incline the seat of the wheelchair backwards, this
means you are seated more deeply and firmly in the chair. To
lean the seat backwards, you have to move the quick-release
axle to a higher position. If you want to incline the seat for-
wards, fix the quick-release axle in a lower position. The
quick-release axle is fixed in the same way as in 7.8. .
