6.6.3 Safety information when taking obstacles

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.

6.6.4 The correct way to take obstacles

The following instructions how to take obstacles also
apply for attendants if the mobility device is fitted
with an attendant control.

Fig. 6-1 Right
Ascending
1. Approach the obstacle or the curb slowly, head-on and
at a right angle.
2. Depending on the wheel drive type, stop in one of the
following positions:
a. In the case of centrally driven mobility devices: 5 -
10 cm before the obstacle.
b. For all other drives: approx. 30 - 50 cm in front of
the obstacle.
3. Check the position of the front wheels. They must be in
driving direction and at right angles to the obstacle.
4. Approach slowly and keep at a consistent speed until
the rear wheels have also passed over the obstacle.
Ascending obstacles with a curb climber
1. Approach the obstacle or the curb slowly, head-on and
at a right angle.
2. Stop in the following position: 30 – 50 cm in front of
the obstacle.
3. Check the position of the front wheels. They must be in
driving direction and at right angles to the obstacle.
4. Approach with full speed until the curb climber makes
contact with the obstacle. The impetus will lift both
front wheels over the obstacle.
5. Keep at a consistent speed until the rear wheels have
also passed over the obstacle.
