6.13 Adjusting the wheel adapter with 22"/24" drive wheels (custom fabrication version)

WARNING
Incorrectly adjusted wheelbase
Tipping over, falling of the user due to incorrect adjustment
► Only adjust the wheel adapter after completing the adjustments described above.
► Maximum stability is achieved when the frame is set in the lowest position and the rear wheels are set in the
rearmost position. Deviations from this setting reduce the stability of the mobility base for seating shells.
► Avoid extreme settings that could lead to tipping when adjusting the seat angle.
► Please note that with the rear wheel in a more forward mounting position and with an unfavourable body posi­
tion, the user may tip backwards even on level ground.
► Position the drive wheels towards the rear for transfemoral amputees. This improves the stability of the
product.
► Changing the size and position of the drive wheels may cause the caster wheels to wobble at higher speeds.
If changes are required, verify the horizontal alignment of the main frame.
WARNING
Improper assembly of removable wheels
Tipping, falling over of the user due to wheels coming off
► After each assembly, verify the proper fit of the removable wheels. The quick-release axles must be firmly
locked in the wheel attachment.
INFORMATION
To change the position of the wheel adapter, the knee lever wheel lock first has to be loosened and subsequently
readjusted ().
If 22"/24" drive wheels are installed, the wheelbase can be adjusted on a special wheel adapter. This has the fol­
lowing effects:
Position of the wheel adapter / drive wheel
Shifting to the rear (farther away from the seating centre
of gravity)
Shifting forward (closer to the seating centre of gravity)
The permissible positions of the wheel adapter on the main frame are determined by the wheel size:

Effect
Larger wheelbase; tipping resistance increases; mobil­
ity base for seating shells is harder to tip backwards
when crossing obstacles;
larger forces required for tipping
Smaller wheelbase; tipping resistance decreases;
mobility base for seating shells is easier to tip back­
wards when crossing obstacles;
lower forces required for tipping
