and also for aged persons.
When providing for individual requirements:
body size and weight (max. 100kg (220.5 lb.))
physical and psychological condition
residential circumstances
environment
should be taken into consideration.
Your wheelchair should only be used on surfaces where all four wheels are touching the
ground and where there is sufficient contact to propel the wheels equally.
You should practice for use on uneven surfaces (cobblestones, etc.), slopes, curves and to
get past obstacles (kerbs, etc.).
The wheelchair should not be used as a ladder, nor is it a transport for heavy or hot objects.
When used on mats, carpeted floors or loose floor coverings, the floor covering can get
damaged.

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 foot bracket.
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, kerbs, 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 When transporting the wheelchair, never pick it up by grasping movable parts (wheels,
seat cushion, etc.)
L To be better visible when driving in the dark, wear the brightest possible clothing or
clothes with reflectors.
L Be careful when using possible causes of fire such as cigarettes since they may set the
seat and back covers alight.
L Never exceed the maximum load of 100 kg (220.5 lb.).
L To avoid hand injuries, do not grasp the wheelchair between the driving wheels and the
sportbrakes.

4. Swing your arms loosely back to the hand rims topside and repeat the movement.
2.8 Moving on slopes
LWARNING: Control your speed –Moving on slopes as slow as possible.
LWARNING: Consider the capacities of your attendant –If your attendant does not
have enough force to control the wheelchair, put on the brakes.
LWARNING: Risk of tipping over –Lean forward to move your centre of gravity
forward. To improve a better stability.
1. If available on the wheelchair, wear the safety belt.
2. Do not attempt moving on too high slopes. The maximum
slope angles (upwards and downwards) are mentioned in
table 1 and 2.
3. Ask an attendant to help you moving on the slope.
4. Lean forward to move your centre of gravity forward.
2.9 Negotiating steps or kerbs
2.9.1 Getting down steps or kerbs
Riding down low kerbs can be done moving forwards. Make sure that the foot bracket does
not touch the ground. A practiced user can negotiate small steps or kerbs by himself:
L WARNING: Risk of tipping over –If you do not have
enough experience with your wheelchair, ask
assistance of an attendant.
1. Bring balance on the rear wheels to reduce the pressure on
the front wheels.
2. Negotiate the kerbs.
Higher kerbs can be taken forward with an attendant:
1. Ask the attendant to tip the wheelchair slightly backwards.
2. Get past the kerbs while moving on the rear wheels.
3. Put the wheelchair back on the four wheels.
An experienced user can negotiate higher kerbs by himself. This is
best done backwards.
1. Turn the wheelchair to have the rear wheels facing the
kerb.
2. Lean forward to move your centre of gravity forward.
3. Move the wheelchair close to the kerbs.
4. Use the hand rim to roll-off wheelchair from the kerb in a
controlled manner.
