CAUTION!
Risk of tipping over
– Never approach obstacles at an angle but at 90
degrees as shown below.
– Approach obstacles followed by a gradient with
caution. If unsure whether the gradient is too
steep or not, move away from the obstacle and
if possible try to find another location.
– Never approach obstacles on an uneven and/or
loose ground.
– Never drive with too low tire pressure.
– Put your backrest into an upright position
before ascending an obstacle.
CAUTION!
Risk of falling out of the mobility device and
damage to the mobility device such as broken
casters
– Never approach obstacles that are higher than
the maximum climbable obstacle height.
– Never let the footrest/legrest touch the ground
when descending an obstacle.
– If unsure whether taking an obstacle is possible
or not, move away from the obstacle and if
possible find another location.

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.
