Selecting and adjusting the suspensions
CAUTION
Incorrect settings or dimensioning of the suspensions
Injuries to the user due to changed driving characteristics and insufficient tipping resistance
Check whether the selected suspension types are permissible for the new configuration. Replace the suspen-
sions if necessary.
Adjust the suspensions to the total weight of the wheelchair. Incorrect settings can lead to an incorrect seat
height, insufficient ground clearance and changed braking and driving characteristics. The motors can be da-
maged and the wheelchair may tip.
Do not attempt to compensate for insufficient spring stiffness by adjusting the spring tension.
