Settings
Start M1

WARNING
Incorrectly adjusted wheelbase
Tipping over, falling of the user due to unstable settings
►Please note that with the drive wheel in a more forward mounting position and with an unfavourable body pos
ition, the user may tip backwards even on level ground.
►Use an anti-tipper for inexperienced users and with extreme settings of the drive wheel.
►Be sure to position the drive wheels towards the rear for transfemoral amputees. This improves the stability of
the wheelchair.
INFORMATION
Changing the rear wheel position can also change the angle between the caster wheel journal and the ground.
However, this must be approx. 90°. Please note that with this wheelchair, the angle can only be influenced by
changing the caster wheel position in the fork and by using caster wheels of different sizes.
The knee lever wheel lock also has to be readjusted.
6.2.1 Adjusting the height of the drive wheels
Changing the drive wheel position has the following effects:
Drive wheel position Effects
Move upwards • The higher the drive wheel position, the more the seat surface is tilted to
the rear
• Wheelchair is easier to tip backwards when crossing obstacles
• The change in the centre of gravity results in a lower, more stable seat
position in the wheelchair
• The seat height can be further adjusted in combination with a height
adjustment of the caster wheels.
Move downwards • The lower the drive wheel position, the less the seat surface is tilted to the
rear
• Wheelchair is harder to tip backwards when crossing obstacles
• The seat height can be further adjusted in combination with a height
adjustment of the caster wheels.
The drive wheel adapter can be adjusted vertically to five positions. The fitting can also be shifted vertically by a
small amount in the drive wheel adapter (fine adjustment).
