1 SAFETY RECOMMENDATIONS
Read this manual carefully before using the wheelchair. It will guide you on flexible and safe use of
the wheelchair and advise you on the procedures for problem situations. Please contact the supplier
if you have any further questions.
The wheelchair is intended for outdoor use, where it can cross obstacles in normal outdoor
conditions and drive on uneven ground. The wheelchair can also be used in suitable indoor premises.
1.1 Applicability for different type of users
Wheelchair is intended for person who has active life with the family. Wheelchair is also suitable for
persons who want to move and act independently both in the city and in the countryside.
The wheelchair is intended for users weighing not more than 125kg and having the ability to learn
the correct use of the equipment and the physical preconditions for using the controlling system and
the necessary equipment.
Wheelchair is perfectly suitable for persons whose injury / disease demands soft drive and stability of
the seat (there is special flexible chassis structure in the wheelchair). Wheelchair is suitable for
instance for accident patients, multiple sclerosis patients, brain infarct patients, overweight persons
and arthropathy patients.
Wheelchair is not suitable for visually disabled / blind person; badly spastic person whose moves are
so uncontrollable that controlling the wheelchair is impossible; disabled person who is not able to
understand the correct function of the wheelchair or he doesn’t have the physical preconditions for
using the wheelchair; person whose weight cross the maximum user weight. These features which
limit the wheelchair use can be a risk both to the wheelchair user and to the person around and to
the other environment. Risks can be, among others, losing the control of the wheelchair (falling
down, crashing) when the wheelchair user and persons nearby are exposed to danger; damaging of
the wheelchair structure when using features and safety of the wheelchair weaken.
Risks mentioned above can be prevent by installing the assistant control system into the wheelchair
when controlling and driving of the wheelchair are happening by assistant and then user is not able
to use the control system of the wheelchair.

1.2 Safe driving
Do not use the wheelchair if you suspect that the use would not be safe. For safety, take notice of
the wheelchair’s condition, function and noises, environmental conditions and the users’ ability to
control the wheelchair. Check the wheelchair’s condition weekly at the very least.
The wheelchair has moving parts, such as the wheels,
rods and joints. Take note of the dangers your
wheelchair may cause especially in the presence of
children and pets. Make sure they remain at a safe
distance from the wheelchair. The places that are
especially dangerous are marked with these symbols:
Avoid loose clothing or jewellery, which can become
entangled in the moving parts.
If you are aware of a fault in the driving controller or any other critical part, do not drive the
wheelchair but deliver it immediately for service.
Brake releases must be returned to the DRIVE – position (D) after pushing or towing.
Using the chair on sloped surfaces can be dangerous if the brakes are released.
The wheelchair has four wheel drive and steering. Mastering the driving technique requires practice.
Avoid places where a loss of wheel grip can be dangerous, for example wet, sloping lawns.
The wheelchair has a balance adjustment system for improving driving safety and the overcoming of
obstacles. It is necessary to learn its correct use. Always check before driving that the seat is in the
correct position. Look at the section “Balance adjustment”.
Instability can arise when driving on slope if the balance is adjusted incorrectly. Adjusting the
balance on a sloped surface requires special caution.
The hill climbing capacity of the wheelchair is greater than the maximum safe driving declination.
Driving on a steeper ground than a slope of 10°, which is equivalent to a climb of one meter over
five meters, may be dangerous. Also, level differences greater than 100mm can be dangerous (see
the pictures below).
Always use low driving speed and avoid extreme steering movements when driving on a slope or
uneven surface.
At no time it is permitted to use battery box top cover situated at the rear of the wheelchair as a
seat or for carrying large heavy items. If used for this purpose the warranty of the chair is void.
DX-2 www.chasswheel.com
rev. 1 2014-05-08

Page 9
Driving in water is forbidden due to the danger of damaging the wheelchairs electric parts.
Always use lights in the twilight and dark in order to see any obstacles and dangers in your driving
path. It is also important that the other road users can see you.
Releasing the joystick stops the chair. In emergency situations the wheelchair can also be stopped
by switching off the driving controller.
Take note of the battery charge level before and while driving. Always recharge the batteries when
possible. The wheelchair’s standard charging equipment will not overcharge the batteries.
The wheelchair operations may be disturbed in electromagnetic fields, which may be emitted by e.g.
mobile phones or other similarly emitting equipment. The wheelchair itself can disturb equipment
based on electromagnetic fields, such as shop alarm systems.
Don’t leave the wheelchair under the straight sun light. Metal parts and surfaces of the wheelchair
for example the seat and the cushions of the armrests might heat easily. Also avoid leaving the
wheelchair under high freeze.
After driving under moisture circumstances, take care of drying the wheelchair for example by
storing it in a warm space. Do not leave the wheelchair outside or in cold and moisture spaces. Not
following these instructions might damage the wheelchair.

Page 10
1.3 Safe use and service
The wheelchair’s driving controller has factory settings, which are suitable for most users. It is
possible to change some of these settings. Programming should only be performed by healthcare
professionals with adequate knowledge of the controller system. Incorrect programming can create
dangerous driving properties or damage the controller system.
The reliability of the wheelchair and the control system is improved, if you keep exposure to extreme
conditions to a minimum.
Damaged wheelchair cables create a safety risk.
Check the condition of the tyres regularly. It is important for the steering properties and grip abilities
to have a correct tyre pressure. Measuring the tyre pressure is explained in section “Wheelchair
servicing”.
Use the locking key to prevent illicit use of the wheelchair. Someone other than the owner using the
wheelchair is a safety risk.
Always attach the wheelchair to the car’s body part during transport. Sitting in the wheelchair during
transportation is Allowed with CW4 Four X DL model.
Unauthorized repairs and modifications are forbidden. The user may perform the servicing
operations referred to in section “wheelchair servicing”. When the wheelchair is being serviced or
adjusted, the driving controller must be switched off.
Using the other than gel batteries is forbidden due to the danger of damaging the wheelchair’s
electric parts.
Handling tools in close proximity to the batteries may cause short circuit. Handling an open flame is
forbidden because of the danger of explosion. The battery casing is not intended to be used as a
storage container. The cables in the battery naves should not disconnect on one’s own. In the
problem situation, please contact the service.

driving controller (see chapter 2.8.3). The back rest is then
adjusted by moving the joystick forwards and backwards.
2.11.4 Head support adjustment
In order to adjust the height of the
head-rest, the plastic butterfly nut (1)
at the back of the head-rest needs to
be loosened until the head-rest can
move freely on its attachment. Once
the desired height has been achieved,
the butterfly nut has to be tightened up
again. The height of the head-rest can
be adjusted smoothly.
In order to adjust the depth of the
head-rest, the plastic butterfly nut (2)
behind the rod needs to be loosened
until the head-rest can move freely on
its attachment. Once the desired
position has been achieved, the
butterfly nut has to be tightened up
again. The depth of the head-rest can
be adjusted smoothly.
The padding of the head-rest is
attached to the rod by a globe joint (3).
The padding can be easily changed
according to the user's head position.

2.11.6 Adjustment of a manually adjustable foot rest
The distance of the leg support from the chair is adjusted by loosening the retaining knobs (1) in
front part of the seat. When the correct distance is found, retighten the screws. The length is
adjusted with a 5mm hexagonal key (2).
The foot rest angle (3) can be adjusted with a 13mm open spanner. The foot rest is adjusted by
raising the lever (4), which releases the lock and the position can be adjusted. When the correct
position has been found, release the lever. The foot support is now locked into this position.
It is necessary to observe the foot rest position when driving uphill or negotiating obstacles.
Repeated striking of obstacles on the foot support may damage it.
2.11.7 Adjustment of an electrically adjustable foot rest with lenght
compensation
Adjustment of distance, length and the foot rest angle is carried out similarly to the mechanical foot
rest. The foot rest angle is adjusted by choosing foot rest adjustment on the driving controller (see
chapter 2.8.3). The operational mode is chosen when the displayed foot rest is highlighted. The foot
rest is adjusted by moving the joystick forwards and backwards.

2.12 Other devices and supplies
2.12.1 Seat belt use
The wheelchair is equipped with a safety belt. Its use
is recommended. If the safety belt is not used, it
should be prevented from dangling and getting
entangled to the wheels.
2.12.2 Tyres
All the tyres of the wheelchair are the same and because of their tread pattern they have a good
grip on different surfaces.
The tyre pressure should be checked regularly. Measuring the tyre pressure is defined in section
“wheelchair servicing”.
2.12.3 Batteries
Service-free gel batteries are used as the wheelchair’s
standard batteries. Using other than gel batteries is
forbidden due to a risk of electronic damage. The batteries
are situated in a case behind the back rest, which can be
opened by turning the screw located at the centre of the
lid. Instructions for removing and installing the batteries
are in section “wheelchair servicing”. Take note of the
safety instructions regarding the batteries in section
“safety recommendations”. Used batteries should deliver to
the proper recycle places.
Note! Do not sit on the batterybox!
2.12.4 Battery recharging
The wheelchair batteries are recharged by connecting the charger plug into the driving controller’s
charger socket. During recharging, the battery charge level is shown as an icon on the display and
the wheelchair will not be possible to drive. Batteries must be recharged immediately, if the icon
indicating the battery charge level shows only two full pillars. Follow the instructions supplied with
the charger.
Use only the charger that has been supplied with the wheelchair.
Using incorrect chargers could damage the batteries, wheelchair or the charger itself.

3.2 Drive practice
Familiarize yourself with the wheelchair’s performance capacity gradually and on different terrains,
such as sand, snow, ice, off-road paths etc. to find the correct adjustments, speeds and ways of
steering for different situations. Drive practice is also necessary for learning safe and flexible use of
the wheelchair in different driving situations. It is especially important to learn the correct use of the
balance adjustment system. Start practicing at a low maximum speed, when it is easier to control
the wheelchair. As the wheelchair has four motors and four-wheel steering, its capacity is great and
therefore utmost caution should be applied in the beginning.
The speed and direction of the wheelchair is adjusted by the joystick. By pushing the joystick
forwards or backwards, the wheelchair moves to the direction determined by the current wheel
position. If the wheels are turned so that the right side wheels are close to each other (picture 2),
the wheelchair will move forward to the right when the joystick is pushed forward (Picture 3A) and
backwards to the right by pulling the joystick backwards (Picture 3b).
The driving direction is corrected by moving the joystick sideways. After this, keep pushing the
joystick straight forward and make only small sideways movements until the correct drive direction is
found. Avoid extreme movements and start driving slowly to find the correct feel. If the wheelchair
moves in an undesired way, release the joystick. This stops the wheelchair in all situations. In
emergency situations switch the driving controller off. When you have learned how to use the
wheelchair on a level surface, you can start practicing how to negotiate obstacles and hills, where it
is essential to master the balance adjustment system.
DX-2 www.chasswheel.com
rev. 1 2014-05-08

Page 37
3.3 Balance adjustment
The balance adjustment system means that the seat can be moved in relation to the frame. In
addition, when the seat is moved backwards, it starts to tilt at a certain stage.
For adjusting the balance, the driving controller must be set to the balance adjustment mode. This
mode is accessed by pressing the MODE button, until the display shows the seat parts (back rest and
seat plate) darkened. The balance is adjusted by moving the joystick forwards and backwards. When
the joystick is pushed forwards, the seat moves forward in relation to the frame.
In the drive position for even ground the seat starts to tilt backwards while the balance is shifted
backwards. The recommended balance positions for driving uphill, on even ground and downhill are
represented in the pictures below.
Avoid driving uphill if the seat is moved backwards. Do not drive downhill, if the seat is moved
forwards. These positions are incorrect and can be dangerous.
Adjust the maximum speed lower when driving up or downhill and when crossing high obstacles.
In case of a fault in the balance adjustment actuator, in its connecting cable or in the joystick
module, the seat is left in the position in which it is when the fault occurs. This may lead to a
situation in which the user has to drive with an incorrect balance adjustment, which in turn may lead
to the fall of the wheelchair.

3.4 Climbing Steps
Approach the step slightly sideways so that the wheelchair is able to mount the step one wheel at a
time. Move the balance position backwards and raise the foot rest so that it doesn't hit the step.
Drive the wheelchair’s front wheels onto the step.

4 FREEWHEELING
Malfunctions, transport etc. may demand that the wheelchair should be towed. To make this possible
the brake releases must be switched on. This can be done by turning the levers (4 pcs) in both axles
towards the outside of the wheelchair. When the parking brakes are released, the wheelchair cannot
be driven, and therefore controlling it is difficult and moving it on a sloping surface is dangerous.
During the towing the driving controller must be switched off. When freewheeling, notice that it is
forbidden to push the wheelchair. Only the person (for example attendant) who is capable to handle
the wheelchair, because controlling is difficult and moving it on a sloping surface is dangerous, is
allowed to engage and disengage the drive system. When this is done the system must be turned off
and on again.
5 TRANSPORTATION AND PACKAGING OF THE WHEELCHAIR
Transferring the wheelchair into the vehicle must be done with ramps or hoister that is located in
vehicle.
Behind the wheelchair’s seat, there are attachment rings on the fastening pipes for the arm rests
(picture 1), to which attachment straps can be fastened during transportation. When strapping the
wheelchair, care must be taken that the wheelchair's electric cabling is not damaged. During
transportation it must be assured that the brakes are not released and the control module is well
protected.
Sitting in the wheelchair during transportation is allowed with CW4 Model Four X DL. use the car’s
own seat during transport when required.
Additional equipment includes wheelchair bars that can be connected to the both axle pipes (picture
2). These wheelchair bars can be connected to a car’s chassis at four points. It is also possible to
attach a rope to the bars, so the wheelchair can be towed in the case of electric malfunction etc.
For transporting the wheelchair on an aeroplane, a ship, a train or other means of transport, contact
the organiser of transportation to receive transport instructions.

If the wheelchair needs to be packed, drive the wheelchair on the pallet. Notice that the user cannot
be in the wheelchair while driving it on the pallet. Wheelchair should be attached to the pallet like it
is attached for the transportation (see pictures 1 and 2). Footrest should be bent down and foot
plate up. Head support is good to be adjusted in the lowest position. If necessary the head suppoert
can be removed and attach on the seat. Back rest can be bent forwards by pulling the lever on the
side of the back rest (see page 17, part “Manually adjustable back rest”). If wanted the wheelchair
can be covered for example wooden frame or cardboard box.
The wheelchair can be moved for example to truck by driving it or if the wheelchair is on the pallet,
by loading pump.
6 WHEELCHAIR SERVICING
After driving under moisture circumstances, take care of drying the wheelchair for example by
storing it in a warm space. Do not leave the wheelchair outside or in cold and moisture spaces. Not
following these instructions might damage the wheelchair.
By servicing the wheelchair regularly, you ensure the functioning and safety of your wheelchair. A
well serviced wheelchair is a long-term aid and it can last at least ten years if service is taken care
of. Part of the servicing can be performed by users themselves (these operations are mentioned
below). However, the more demanding service operations (such as electrical malfunctions, driving
motors, actuators, frame parts, seat parts, foot and arm rests, changing the tyres and other
technical problems) can only be done by a qualified technician in order to maintain the warranty.
The manufacturer intends the wheelchair to be serviced/maintenanced by qualified technician (either
distributor, service agent or the manufacturer) at least once a year.
Service card of the wheelchair is in the last pages of the Owner’s manual. Please take care of that
the Owner’s manual goes with the wheelchair to the service. When it is a time to service the
wheelchair, please contact to your FOUR X distributor.
Following routine operations the manufacturer intends the user to be responsible:
- daily inspections
- weekly inspections
- cleaning the wheelchair
If necessary the user could ask assistant or some other person for help.
6.1 Daily inspections
Before beginning the drive check the general condition of the wheelchair visually. When the driving
controller is switched off, check that the joystick is not bent or damaged and that it returns to the
middle when released. Check that all the connectors are in place and undamaged and the cables are
in good condition. Check that the thin protective rubber around the steering stick is not damaged.
Handle the protective rubber with care. Make sure that the control module is well attached to the
wheel chair. Do not over tighten the screws.
DX-2 www.chasswheel.com
rev. 1 2014-05-08

Page 41
6.2 Weekly inspections
Brake tests are made on an even floor, with at least one meter of free space around the wheelchair.
Switch on the control system. Check that the light bar is lit in one second or flashes slowly. Push the
joystick slowly forwards until you hear the parking brakes working. The wheelchair may start
moving. Release the joystick immediately, and you should be able to hear the sound of the brakes
operating in a few seconds. Repeat this test three times also by pushing the joystick backwards, and
to the left and right.
Check the operation of the lights, turn indicators and the balance adjustment. If the wheelchair has
an electrically adjustable back and/or foot rest, also check their operation. In problem situations, do
not use the wheelchair, but contact service.
6.3 Cleaning and disinfection the wheelchair
Clean the wheelchair with a moist soft fabric and diluted cleaning fluid. Avoid the use of undiluted
cleaning fluids as these may damage the plastic and fabric parts of the wheelchair. Follow the
recommendations set by the cleaning fluid manufacturers regarding the different materials. In the
event of the control module becoming dirty, it must be cleaned immediately. Pressure cleaning or
use of a shower is forbidden, as the wheelchair has electric units, which will be damage when wet.
The wheelchair can be disinfected totally for example by spraying the disinfectant on the wheelchair.
The electronics of the wheelchair are in the battery box so keep the battery box closed during the
disinfection. While disinfecting, notice the wheelchair’s texture surfaces (seat, supports) which should
be disinfected with the suitable methods.
All the materials are tested acc. to ISO 7176-16 and the materials are inflammable.
Following operations
- measuring the tyre air pressure
- changing tyres
- disconnecting the batteries
- installing the batteries
- changing the lamp
the user is able to do with help of assistant or some other person:
6.4 Measuring the tyre air pressure
The suitable air pressure in the tyre is approx. 1.5 bar.
Air pressure decrease under 1.2 bar and filling over 3.0
bar is not advised. This increases the wear of tyres,
decreases grip and causes extra friction, which shortens
the driving distance.

Page 42
6.5 Tyre change
The rim is attached to the motors hub with five coach screws, tool size 6mm. Support the axle so
that the tyre is off the ground. After that release the air pressure from the tyre. When and only
when you have done this open the screws and take of the tyre. Both halves of the rim are attached
to each other with screws, which you are not allowed to open until you have released the air
pressure.
Assembling the wheel with tyre.
Install inner tube into the outer tyre and install this packet onto the rim half. Attach both rim halves
together with screws. Pay attention that the inner tube does not squeeze between the rim halves.
Now fill the tyre a little bit (0.5bar) to get the inner tube straight. After this install the tyre onto the
motors hub with coach screws. When tyre is attached to the motor, fill up the tyre (approx. 3bar is
reasonable). After this remove lifting equipment and the chair is ready to drive again.
6.6 Disconnecting the batteries
Detach the cables (- and +) and the main fuse from the batteries using 11mm open ended spanner.
Open the attachment straps.
Lift the batteries from the casing.

10. Use of the wheelchair as a seat in a vehicle
In order to use a wheelchair as a motor vehicle seat, it needs to be equipped with attachment points
to enable anchoring in the motor vehicle. These accessories may be included in the standard scope
of wheelchair order but may also be obtained from Chasswheel as an option.
This power wheelchair complies with the requirements of ISO 7176-19:2001 and may be used as a
vehicle seat in connection with an anchoring system that has been checked and approved in
accordance with ISO 10542. The wheelchair has undergone a crash test in which it was anchored in
the transporting vehicle's direction of travel. Other configurations were not tested. The crash test
dummy was secured using pelvic and upper body safety belts. Both types of safety belt should be
used in order to minimize the risk of injuries to head or upper body. It is imperative that the
wheelchair is inspected by an authorized dealer before being used again after being involved in a
crash. Alterations to the wheelchair anchoring points may not be carried out without the
manufacturer's permission.
Caution: There is a danger of injury if the wheelchair is not properly secured during use
as a vehicle seat!
• If possible, the user should always leave the wheelchair to use a vehicle seat and the safety belts
provided with the vehicle.
• The wheelchair should always be anchored facing in the transport vehicle's intended direction of
travel.
• The wheelchair must always be secured in accordance with the wheelchair and anchoring system
manufacturers’ operating manual.
• Always remove and secure any accessory parts fixed to the wheelchair such as chin controls or
tables.
• If your wheelchair is equipped with an angle adjustable backrest, then it must be placed in an
upright position.
• Fully lower elevated leg rests, if fitted.
• Fully lower the seat lifter, if fitted.
• Always completely lower height-adjustable leg rests, if fitted

1. SAFETY RECOMMENDATIONS
THIS USER MANUAL IS FOR USE, ONLY TOGETHER WITH THE OWNERS HANDBOOK! THIS
SECTION EXPLAINS ONLY CONNECTED MATTERS CONCERNING USE OF THE SEAT RISER SYSTEM.
SAFE DRIVING
Do not use the Seat Riser System, if you suspect that its use is not safe. For safety of use, the
condition of the appliance, environmental conditions and the user’s ability to control the machine
must be observed.
On an inclined surface, driving in the erect position is absolutely forbidden due to the dangers of
overturning.
Do not use the appliance if you suspect that some part may be broken, but deliver the appliance
directly for servicing.
Before raising the lift, ensure that the safety accessories are properly attached.
The appliance is installed with a speed limiter, which limits the maximum speed automatically when
the lift operation is used.
If you suspect that the limiter is not operating properly, do not use the Seat Riser System, but
contact service.
When inclining the back backwards in the sitting position, take care that the back rest does not
create pressure on the battery compartment. This can cause the seat’s spindle motor or battery
compartment to be damaged.
When using the Seat Riser System, ensure that the foot support can move freely.
In a case that the foot support catches on the floor, an obstacle or an axis, stop operations and
adjust the various sections of the seat until the foot support is freed.
Do not push the wheelchair. Use the drawstrings for transferring the wheelchair.

The safety belt must always be adjusted as suitable for the user.
