1.7 Safety rules
L To prevent injury and/or damage to your wheelchair, make sure that no objects
and/or body parts are caught in the spokes of the driving wheels.
L The parking brakes should be applied before getting into and out of the wheelchair.
L When getting into and out of the wheelchair, do not stand on the footplates. These
should be folded up beforehand, or the footrest should be swung completely outwards
out of the way.
L Investigate the effects of shifting the centre of gravity on the behavior of the wheelchair,
for example on up or down gradients, on laterally sloping ground, or when overcoming
obstacles. Obtain support from an attendant.
L If you want to pick up something (lying in front of, on the side, or to the rear of the
wheelchair), you should not lean too far out to avoid tipping over.
L When moving through doors, arches, etc. ensure that there is enough room at the sides
so that you do not get your hands or arms caught or crushed and that there is no
damage to the wheelchair.
L Only use your wheelchair according to regulations. For example, avoid uncontrolled
rolling against obstacles (steps, curbs, doorframes, etc) or dropping down from ledges.
The manufacturer cannot assume liability for damage caused by overloading, collision
or other improper use.
L Stairs may only be negotiated when aided by another person. If furnishings like drive-on,
ramps or lifts are available, use them.
L When moving on the public highway, you are subject to the rules of the road.
L When driving your wheelchair, you should not be under the influence of alcohol or
medicine as in the case of driving other vehicles. This also applies to indoor driving.
L When travelling outdoors, adapt your driving to weather and traffic conditions.
L To be better visible when driving in the dark, wear the brightest possible clothing or
clothes with reflectors, and check that the reflectors mounted on the sides and rear of
the wheelchair are clearly visible.
L Never exceed the maximum load of 130 kg.
