For your own safety, we recommend that
you use the assistance of an accompany-
ing person for driving slopes of more than
1% tilt.
☞
This low gradient value is valid for per-
sons that are not able to effect even
the smallest centre of gravity change
by changing the position of their upper
body.
The accompanying person should be aware
that the control of the wheelchair requires
more strength on a downward slope/ hills
than on a level driving surface and that
there is an increased danger of slipping.
Never lean towards the downhill direction
when driving on rising, falling or transverse
gradients.
Avoid jerky changes of the driving condition
(especially with critically adjusted driving
parameters as for example an active wheel
position).
Never drive faster than walking speed.
There is an increased danger of tilting while
driving backwards.
While driving in curves and when turning
on inclinations and slopes there is a danger
of tilting.
The braking force transferred to the driving
surface is much less on a downward slope
than on a level driving surface and is fur-
ther reduced by poor road conditions (e.g.
rain, snow, grit, dirt). A dangerous slipping
of the wheels due to excessive braking and
an associated unwanted course deviation
must be avoided by way of a careful dosed
braking.
At the end of the downward slope, take care
that the footboard does not make contact
with the ground and endanger you through
a sudden braking effect.
Transverse surfaces to the driving direction
(e.g. transversely sloped pavements) effect
a turning of your wheelchair in the downhill
direction. You or an accompanying person
must compensate for this drift by a coun-
ter-steering.
Crossing obstacles
After having overcome stairs, support cas-
tors that were previously removed need
to be mounted again resp. support cas-
tors that were swivelled to the side, swiv-
elled back into place.
Each crossing of obstacles involves a risk!
Even flat obstacles (e.g. sills, carpet edges,
small steps or similar) represent a danger of
tipping.
The crossing of obstacles is a special dan-
ger situation in which a combination of the
safety advice in the sections headed uphill
driving, downhill driving and driving trans-
verse to a slope must be observed in addi-
tion to other safety advice.
For your own safety all obstacles should
only be driven over with an accompanying
person. The pedal tube is to be used as sup-
port for each manual tilting of the wheel-
chair.
Only with sufficient and safe control of the
wheelchair, is an independent, danger free
passage over small obstacles (< 4 cm) pos-
sible, also when using permitted auxiliary
drives.
Always approach small obstacles, e.g. steps
or curbs, slowly and at a right angle (90°) un-
til the steering wheels almost touch the ob-
stacle. Briefly stop the wheelchair and then
drive over the obstacle.
Always drive over an obstacle forwards (not
backwards) and simultaneously with both
