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.

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.
20
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.
21
10.1.6 seat lift (optional)
The seat lift is centrally mounted into the chassis. With this lift the seat can be raised step less up to 400mm. This enables the user to have more freedom of movement, not only in horizontal area, but also in the vertical area. The seat lift can be stopped at any height and will be automatically locked in position.
whilst lifting the seat, the driving speed will automatically reduced to gain maximum stability at all times. At high seating position also the seat tilt will be blocked to gain maximum stability. the seat height can be set to every height position by the user. The maximum seat height is set to 950 mm (seat pan to ground)
be careful driving in high seating position at slopes. We strongly suggest to only use the seat lift on flat areas. Lifting high on a steep slope might lead to instability and might cause personal or material damage.
The seat lift can also be very helpful for transferring or lifting the user in or out of the wheelchair.
400mm

using other cushions with different thickness might influence the biomechanical function of the legrest and or backrest.
23
10.2.3 seat tilt (optional)
The seat tilt can be used to release pressure. The tilting angle is from 0 to 50°. The tilt can also be used when driving down a slope for compensating the negative seat angle. This provides a more stabile seat position and safe driving.
If the tilt is activated over a certain angle, the driving speed will be reduced. This to reduce the risk of danger whilst driving at high speed.
Always drive carefully on slopes. The angle of the slope has great influence on the total stability of the wheelchair.
When tilting always check if there are no obstructions close to the wheelchair. Especially in the front or rear of the wheelchair.
When tilting, the wheelchair will get longer. This has influence on the driving characteristics of the wheelchair. Make sure there is enough space to drive.

At a reclined backrest position over 135° the driving speed will be automatically reduced for safety reasons.
When reclining always check if there are no obstructions close to the wheelchair. Especially in the rear of the wheelchair.
When reclining, the wheelchair will get longer. This has influence on the driving characteristics of the wheelchair. Make sure there is enough space to drive.
25
10.2.6 upholstered armrest
The upholstered armrests of the seat provide good and comfortable support of the arm which result in a stabile seating position. The armrest has a soft upholstery on the top side. The arm rests come in 320 mm or 400mm length. A biomechanical mechanism makes sure the armrests are always in a good position to supply optimal support. The armrests are adjustable in height, depth, angle and inside angle. For transferring in and out of the chair, the armrests can be flipped up.
10.2.7 legrest
The legrest uses a central mounted tube on which the footplates are mounted. The footplates come in two different sizes. The legrest can be adjusted in length (left and right footplate independent) knee angle and footplate angle (left and right independent). The footplates can be flipped up to decrease the size of the wheelchair for transportation or storage. A build in rail can be used to mount calf supports.
10.2.8 powered legrest adjustment (optional)
With a powered legrest the knee angle can be set from little less than 90° up to a fully stretched leg angle. The biomechanical mechanism ensures the lower leg length will always be the same.
26
If the legrest is stretched over 45° the driving speed will automatically be reduced for safety reasons.
10.2.9 upholstered headrest (optional)
The upholstered headrest is adjustable in height, depth and angle to the requirements of the user. It can be taken off without losing its settings. As a additional option, a rail can be mounted to move the headrest out of centre. Another option is a rotation block to rotate the headrest to the left or right.
When stretching the legrest always check if there are no obstructions close to the wheelchair. Especially in the front of the wheelchair.
When stretching the legrest, the wheelchair will get longer. This has influence on the driving characteristics of the wheelchair. Make sure there is enough space to drive.
If the wheelchair user is transported in a taxi van we strongly advice to use the headrest. This in order to provide you optimal stability whilst driving in the taxi.

The desktop control enables the user to have a table with a centre mounted build-in joystick module. The table can be flipped up sideways for transferring in and out of the wheelchair. The joystick module can be flipped up to use the table as desktop. When flipped up, the driving mode of the wheelchair is automatically blocked. This ensures a safe use of the wheelchair in any position.
30
11. the first set up
Before using, the wheelchair needs to be adjusted and set up for the user. In this chapter we will explain all the setup which needs to be done before the first drive.
11.1 chassis suspension
The suspension of a chassis has been designed to increase the comfort whilst driving. Also climbing steps will be more easier having suspension on the chassis. But suspension can also be a disadvantage. A suspension which is set to soft has a negative influence on the control of the wheelchair. So it is very important to have a good mix.
11.1.1 spring setting
The strength of the spring will be set by turning the ring shown above. By turning it to the right (clockwise) the spring will have more tension and the chassis becomes more stiff. This increases the mechanical traction en improves control. The stiffness of the suspension depends on the user weight. The settings needs to be done by setting and testing. We advise you to start with a more stiff setting, since this results in the best control. If the suspension is too hard, you can set it more soft by turning the ring more counter clockwise. to make sure the balance of the left and right spring is the same, we need to measure the setting.
before using the wheelchair it is vital to make the right set up for the user. A non proper set up of the wheelchair might lead to uncontrolled driving which can result in personal or material damage.
