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.
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.
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.
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.
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 absolutely forbidden without the use of the correct 3 point seatbelt attached fitted
in the vehicle.
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 major serious damage. 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.
