2. KEY DATA
2.1. Restrictions during normal use
2.1.1. Number of people
All Balder wheelchairs are designed to transport one – 1 – person.
Never allow anyone else to ride with you, either behind you or on the footrests.
2.1.2. Surfaces
DANGER
Take care when using the wheelchair on uneven, wet or slippery surfaces
(gravel, loose sand/earth, wet grass, etc.). These are conditions in which
you could overturn or lose control of your chair.
Bear in mind that negotiating obstacles can involve a risk of overturning.
Remember that your chair is heavy. Do not travel in areas where there is
a risk of the surface on which you are travelling collapsing.
Avoid travelling through water more than 7 cm deep. This may damage
the electric motor and systems, as well as the battery.
When travelling on slopes in excess of 6 degrees, remember that this will
affect the stability of the chair and there is a risk of the chair
overturning.
2.1.3. Descending slopes
NOTE
When your vehicle drives downhill, the motor generates energy. This
energy charges the battery. However, if the battery is already fully
charged, it cannot accept the generated energy anymore. When this
happens the battery voltage becomes too high, which can result in
damage to either the controller or the batteries. The controller will try to
prevent this damage and if needed it will ultimately force the vehicle to
halt abruptly.
When you go downhill at a slower speed, the motor will generate less
energy. The batteries will have more time to absorb this energy before
they are fully charged. This will reduce the risk of a sudden halt, and it
will extend the life of the batteries.
