Ascending
1. Approach obstacle or curb slowly, head-on and at a
right angle.
2. Depending on wheel drive type, stop in one of following
positions:
a. In the case of centrally driven mobility devices: 5
- 10 cm before obstacle.
b. For all other drives: approx. 30 - 50 cm in front of
obstacle.
3. Check position of front wheels. They must be in driving
direction and at right angles to obstacle.
4. Approach slowly and keep at consistent speed until rear
wheels have also passed over obstacle.
Ascending Obstacles With Curb Climber
1. Approach obstacle or curb slowly, head-on and at right
angle.
2. Stop in following position: 30 – 50 cm in front of
obstacle.
3. Check position of front wheels. They must be in driving
direction and at right angles to obstacle.
4. Approach with full speed until curb climber makes
contact with obstacle. Impetus will lift both front
wheels over obstacle.
5. Keep at consistent speed until rear wheels have also
passed over obstacle.

Descending
The approach to descend an obstacle is the same as to
ascend it with the difference that you need not to stop
before descending.
1. Descend obstacle with medium speed.
When descending an obstacle too slowly it could
happen that the antitippers get stuck and lift the
drive wheels off the ground. Driving the mobility
device is then no longer possible.
