7. Intended use / intended user
The Leon F Kameleon powered wheelchair is meant to provide mobility to
persons who are not able to walk, stand or use a manual wheelchair, but who
are very well able to control and use the interface of a powered wheelchair.
The wheelchair is designed for a maximum user weight of 57 kg.
Apart from the horizontal mobility, the Leon F Kameleon provides the user with
mobility in vertical direction. For example, to reach light switches, a doorbell
and doorknobs.
It is strongly suggested to have the use of the wheelchair evaluated by a
trained doctor, therapist or other qualified and trained staff.
This wheelchair is not suitable for persons who do not have the cognitive skills
to drive a powered wheelchair by themselves. Also, it is not suitable
for visually impaired persons.
8. Intended environment
The Leon F Kameleon powered wheelchair is not restricted to only indoor or
only outdoor use. Because the large driving wheels are placed in the front, the
wheelchair is extremely maneuverable and is able to cope with many terrain
differences. This, combined with the compact size of the product and the
excellent speed range and battery capacity, making the wheelchair suitable for
both indoor and outdoor use.
It is allowed to use the wheelchair in different weather conditions. It can be
used at temperatures of -25 degrees up to maximum 55 degrees Celsius.
However, it must be noticed that metal or plastic surfaces of the wheelchair
can become very hot when exposed to direct sun for longer time.
Because of the harmful combination of saltwater and sand, it is advised not to
use the wheelchair on beaches. We advise to clean the wheelchair after
having been in contact with sand and/or saltwater as described in the
paragraph “cleaning”.
9. Tyre pressure
The Leon F Kameleon uses air-filled front tyres and solid or air-filled tyres in
the rear. The choice of having solid or air-filled rear tyres is made by the user
during the ordering of the wheelchair. In order to prevent tyre damage and to
preserve the performance of the wheelchair, the tyre pressure must be
checked at least on a monthly basis. The tyre pressure should be:
Front air-filled tyres (Large): max. 240 Kpa / 35 PSI / 2.4 bar
Rear air-filled tyres (Small): max. 350 Kpa / 50 PSI / 3.5 bar

10. Wheelchair
10.1. Chassis
The chassis is the base of the wheelchair. It contains wheels, drive motors,
batteries and electronics. The steel parts of the chassis are electrolytic
anodized and powder coated to ensure a long life without corrosion.
Each of the front wheels is propelled by a powerful drive motor. These motors
also take care for the steering of the wheelchair. With this system it is possible
to turn on the spot. This makes the wheelchair optimal for indoor use.
10.1.1 Chassis suspension
The chassis has independent suspension on each of the four wheels. The
stiffness can be adjusted to your personal requirements.

10.1.2 Anti-tippers
The anti-tippers prevent the wheelchair tipping over at all time. The anti-
tippers are standard equipped and positioned at the front of the chassis.
10.1.3 Lights and reflectors (Optional)
The chassis has very strong and bright LED lights to make sure you can have
a safe drive in the dark. The orange reflectors on both sides and the red
reflectors in the rear also make you visible for other people as well. The lights
fulfill the European requirements.
The additional LED indicators give our environment clear information in which
direction you want to go.

DO NOT operate the wheelchair without anti-tippers being installed,
otherwise the wheelchair might tip over and hurt the user.

10.1.4 Battery compartments
The batteries are mounted as low as possible in the center into the chassis, to
provide an optimal center point of gravity. This results in a maximum stability
of the wheelchair. The compartment can hold maintenance-free batteries up to
80Ah. For the specification of the batteries see the chapter technical
specifications.
The maintenance-free batteries can be reached from the front side.
The batteries are placed in a box with a handle for easy changing. For more
details of changing the batteries, please check the paragraph “battery
replacement”.

10.1.5 Main fuse
The chassis contains a main fuse which is located at the rear of the chassis.
The main fuse protects the whole electrical system of the wheelchair. This
fuse will only blow if there is a serious problem on the wheelchair.
This situation happens typically when the wheelchair is climbing up a hill that
is steeper than what is restricted. Should the circuit breaker pop-up, you need
Before reconnecting the battery, read the wiring instructions on the inside
of the battery cover.

lead to material damage to the wheelchair.
