3 General description
Comfort is of paramount importance to many
people who make use of a wheelchair. And this
is exactly what this electrical driven wheelchair
offers: an unknown degree of driving comfort.
A distinctive feature is the unique independent
suspension system, which absorbs not only
shocks, but also vibrations.

3.2 Confi gurations
Generally speaking, the wheelchair comprises
a chassis with a seating system on top. This
special chassis makes it possible for the
wheelchair to be confi gured as front wheel drive
or rear wheel-drive. The wheelchair is available
in different speeds (6 km/h & 10 km/h).
In addition, the Puma 20 can be supplied with
two different types of tyres (for indoor and
outdoor use). This will have an effect on certain
specifi cations.
3.3 The user
Driving an electric wheelchair requires a user
to have cognitive, physical and visual skills.
The user must be able to estimate and correct
the results of actions taken when operating the
wheelchair.
The wheelchair may not transport more than
one person at a time. The maximum user
weight is 136 kg unless otherwise indicated
on the identifi cation plate. Additional weight,
such as rucksacks, accessories or medical
apparatus, must be added to the user’s weight
to determine the maximum weight, which may
not be exceeded.
