Warning
Driving Over Curbs
Do not drive the wheelchair over any curbs or edges higher than indicated in chapter 11: Specification.
When driving over a curb or similarly elevated surface, cross the surface at a 90⁰ angle
(perpendicular). Crossing such surfaces at any other angle may cause the wheelchair to tip over.
Reduce speed when driving on uneven terrain or soft surfaces.
Do not use the wheelchair on stairs or escalators. Always use an elevator.
Do not drive the wheelchair on hazardous surfaces (such as steep slopes, uneven terrain or soft
surfaces) in the standing mode.
When feeling unsafe (for example when riding on a cobblestone road or similar surface) during
usage, go back to sitting position or turn off the automatic balancing.
Do not lift or move the wheelchair by any of its removable parts. Doing so could lead to personal
injury and property damage, including damage to the wheelchair.
Warning
Do not drive the wheelchair on side slopes steeper than indicated in chapter 11: Specification if you
can avoid it. There is a risk of tipping.
Changing the seat from the default location changes the center of mass and increases the risk of
tipping. Therefore, use the Seat Elevator, Sit to Stand and Seat Forward functions with extreme
caution and at low speed.
Avoid driving on ramps that do not have proper edge protection.
Warning
When driving over critical slopes, it is recommended that the user be in sitting position. When driving
over critical slopes, the maximum speed of the wheelchair slows down.
It slows down to 75% of the max speed under the following circumstances:
Slope is steeper than 7º while in the sitting position.
The wheelchair slows down to 50% of the maximum speed under the following circumstances:
Slope is steeper than 11º while in the sitting position.
Slope is steeper than 4º while in the standing position.
The wheelchair slows down to 25% of the maximum speed under the following circumstances:
Slope is steeper than 7º while in the standing position
If the surface is too bumpy, consider turning-off the balancing system.
