7. intended use / intended user
The EvO 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. Apart from the
horizontal mobility, the EvO powered wheel provides the user with mobility in
vertical direction. This for example to reach light switches, a door bell and
doorknobs. The wheelchair is designed for a maximum user weight of 140 kg.
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 EvO powered wheelchair is not restricted to only inside or only outside
use. Because the large driving wheels are placed in front, the wheelchair is
extremely maneuverable and is able to cope with many terrain differences.
This, combined with the compact size of the EvO and the excellent speed
range and battery capacity, makes 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. It however 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 salt water 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 salt water as described in the
paragraph “cleaning”.
9. tyre pressure
The EvO 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:
Large front air filled tyres : max. 300 Kpa / 43.5 PSI / 3 bar
Small rear air filled tyres : max. 200 Kpa / 29.0 PSI / 2 bar
The tire pressure is also show on the stickers in the rims of the chassis.

10. the wheelchair
10.1. chassis
The chassis is the base of the wheelchair. It contains wheels, drive motors,
batteries, electronics and seat lift. 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.

you will find in chapter "transportation" .
10.1.3 lights en reflectors
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 on the rear also make you visible for other people as well. The lights
fulfill the European requirements. (E marked)
The additional LED indicators give our environment clear information in which
direction you want to go.

10.1.4 battery compartments
The batteries are mounted as low as possible and as central as possible into
the chassis to provide an optimal centre point of gravity. This results in a
maximum stability of the wheelchair. The compartment can hold maintenance
free batteries up to 85Ah. For the specification of the batteries see the chapter
technical specifications.
The maintenance free batteries can be reached from the side. They can be
replaced whilst the user is still in the wheelchair.
the battery box
To reach the batteries, first remove the locking bolt [A]. Lift up the plastic cover
vertically [B], then pull it off the chassis in the horizontal direction. [C].

After taking the cover off, the maintenance free
battery can be pulled out of the box.
Mind the cables!
At installing the maintenance free battery, one
should pay great attention to make sure the
cables are not jammed between the battery and
the battery box.
when pulling the battery out of the box do mind to not overstretch the
cables. This might lead to technical failure.
before removing the batteries, first remove the main fuse. This to reduce
the risk of short circuit or electrical shock. See the chapter of the main
fuse
before reconnecting the battery, read the wiring instructions on the inside
of the battery cover.

10.1.5 main fuse
The chassis contains a main fuse which is located at the rear of the chassis.
position main fuse
main fuse
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.
The fuse also works as a main switch. By removing the main fuse the batteries
are disconnected. This is important when the wheelchair is transported in an
airplane. To remove the fuse, simply pull the plastic cover off and pull the fuse.
if the main fuse has blown, do not replace the fuse immediately. First
contact your local supplier to have the wheelchair checked .
Only use original main fuses as replacement. Using other fuses might
lead to material damage to the wheelchair.
