2USER INFORMATION
2.1 Warnings
TIPPING HAZARD
Any transport on a slope greater than the maximum security slope can be dangerous.
ELECTROMAGNETIC RADIATION DANGER
The behavior of the wheelchair while driving may be affected by electromagnetic fields
created by transceivers such as: Citizens band (CB) radios, walkie-talkies, fire and police
radios, cellular phones, lap-top computers, two-way radios, and commercial radio and
television broadcast antennas.
PLEASE USE CAUTION in the presence of these devices.
EMI can cause your chair, without warning, to:
• Release its brakes
• Move by itself
• Move in unintended directions
If any of these occur, it could result in severe injury to you or others. EMI can damage the control system of
your chair.
There is no way to know the effect on EMI if you add accessories or modify this chair. Any change to your chair
may increase the risk of EMI. Parts from other suppliers have unknown EMI properties.
The wheelchair might disturb the operation of devices in its environment that emit
electromagnetic fields
TEMPERATURE
The temperature of some surfaces may increase when the chair is exposed to external
heat sources as sunlight.
Do not install, maintain or operate your wheelchair without reading all warnings and this entire user’s
manual.
Always keep this manual in connection with your wheelchair.
NOTICE TO RIDER—WARNING
Do not use your wheelchair on stairs or escalators. Do not lift or move the wheelchair by any of its removable
parts.
The wheelchair should be turned off prior to entering or exiting the wheelchair
The wheelchair may come to a sudden stop at any time during operation.
Do not operate the wheelchair if it is behaving abnormally or erratically.
Do not operate the wheelchair with low batteries, to minimize risk of becoming stranded.
Don’t use the wheelchair if your weight exceed the maximum user weight written in the specification of
this user manual.
Do not carry passengers on the wheelchair independently of the age of the passenger

PINCH HAZARDS –WARNING
Make sure your feet do not “hang up” or get caught in the space between the footrests. In general, make
sure you have proper space in areas you will travel through to minimize pinching or entrapment of body
parts.
Do not use an escalator to move the wheelchair between floors. Serious bodily injury may occur.
Do not lean over the top of the back upholstery to reach objects from behind as this may cause the wheelchair
to tip over.
Do not shift your weight or sitting position toward the direction you are reaching as the wheelchair may tip
over backwards or sideways
Do not tip or wheel the wheelchair with wheel locks. Wheel locks are not brakes.
Do not stand on the frame of the wheelchair.
Always use caution when transferring in or out of the wheelchair. Every precaution should be taken to reduce
the transfer distance. Also be certain the wheel locks are engaged to prevent the wheels from moving.
Caution—Obstacles
Riding over curbs or obstacles can cause tipping and serious bodily harm. If you have any doubt that you can
safely cross any curb or obstacle, ALWAYS ASK FOR HELP. Be aware of your riding skills and personal
limitations. Develop new driving skills only with the help of a companion.
Caution—Anti-Tippers
Using anti-tippers substantially reduces your risk of falling over backwards, which can cause serious injury.
The Anti-Tippers will keep you from falling over, but they will limit your ability to be pulled up curbs and some
other maneuvers. IT IS NOT POSSIBLE TO HAVE THIS WHEELCHAIR WITHOUT ANTI TIPPERS.
The wheelchair is not designed for weight training and is unsafe for use as a seat while weight training.
Weight training from the wheelchair substantially changes the stability of the chair and cause tipping.
The wheelchair is not intended to be dismantled. There is no parts of the wheelchair expected
to be handled during normal use of it.
LIGHTS
It is recommended to not use the wheelchair near public way without lights
turned on.

EVO 3 wheelchair has the possibility of many adjustments to best suit the specific user.
To perform these adjustments they are required a 4 mm allen wrench, a 5 mm allen wrench and
a 8 mm open-end wrench.
These adjustments can be made by the vendor or by an assistant of the user.
2.6.1 Armrests
The available adjustment are in height and angle; these need to be made on the same order as
they are presented.
For the armrest height loosen the four bolts shown in Figure 5 and adjust the height with the
single bolt located upon the support shown in Figure 6. For this operation use the 5 mm allen
wrench
Figure 5
Figure 6
For the armrest angle, you can decide to adjust the horizontal and vertical angle.

www.neatech.it

For the horizontal angle, lift the armrest that you want to modify and unscrew the bolt indicated
in Figure 7; after this you can set the right armrest angle, screwing the bolt to fixing the correct
angle. For this operation use the 4 mm allen wrench
Figure 7
For the vertical angle rotate clockwise the screw shown in Figure 8 to lower the armrest, rotate
counterclockwise the screw to let up the armrest.
Figure 8
2.6.2 Legrest

2.6.3 Backrest
To perform the adjustment of the backrest for different type of height, you have to screw off
the nuts positioned over the four different bolts as it is possible to see in Figure 15.
To screw off the nuts, it is necessary an 8 mm open-end wrench.
Figure 15
After screwed off the nuts it is possible to adjust the height. To facilitate the mounting of the
backrest up the support it may be useful to remove the upholstery of the backrest.
2.6.4 Seat depth
To adjust the seat depth, loosen the 6 bolts on the right side and the 3 bolts on the left side of
the seat, as it is shown in Figure 16.

2.6.5 Drive profile
As default in the wheelchair they are saved some different drive profile for the use indoor and
outdoor.
Additional profiles should be the result of customization for the individual user.
Use the button “PROFILE” of the joystick to change different types of profiles: they are sorted
from the more indoor one to the more outdoor one.
For each profiles it is possible to change the speed.
INDOOR PROFILES
When this profile is activated most of the parameters of the wheelchair are cut off. For example
the maximum speed and the acceleration are limited.
In this way the handling is really improved and there is more margin for mistake on the lever of
the joystick.
In this way it is comfortable to use the wheelchair in indoor environments.
OUTDOOR PROFILES
When this profile is activated most of the parameters of the wheelchair are at the maximum
value. For example the maximum speed and the acceleration are not limited.
In this way it is comfortable to use the wheelchair in outdoor environments.
However remember that the wheelchair EVO3 was designed for use mostly in indoor environments.
