INDICATIONS /
CONTRAINDICATIONS
In case of allergic reactions, skin rashes
and/or pressure sores during the use of
the electric wheelchair sores contact a
doctor immediately.
In order to prevent contact allergies, we
recommend to use the electric wheel-
chair only when wearing clothes.
The functional diversity of the electric
wheelchair permits application in cases
where extreme spasms and contractions of
the skeletal muscles lead to contortions, un-
controlled movements, slipping away and
functional losses as well as substantially to
completely pronounced impairment of the
mobility/walking in cases of structural and/

8
or functional damages to the lower extrem-
ities, such as amputations, results of injury,
musculoskeletal/neuromuskuloskeletally
caused motion disabilities e. g. through:
– paralysis,
– loss of limbs (leg amputation),
– defective/deformed limbs,
– joint contractures/-damages,
– other diseases.
– spasms.
Also to be observed for individual provision
are the physical and psychological state,
age of the user as well as the personal living
condition and private environment.
This is meant for the user of the electric
wheelchair as well as the accompanying
person controlling the electric wheelchair.
Every provision, case by case should be
checked, tested and aligned to the indi-
vidual ability limitations caused by the de-
fined disability through an educated person
(medical device consultant, rehabilitation
consultant u.o.). This also includes that
people that show a counter indications to
the named problems in some cases need
to give proof of the cognitive, mental and
moral ability to operate the electric wheel-
chair.
The electric wheelchair may not be used in
cases of:
– Influence of impairing medications to
the accompanying person (ask your
doctor or pharmacist).
– Extreme balance and/or perceptual
disorders of the accompanying person
(ask your doctor or pharmacist).
– Inability to sit.
– Accompanying persons that are physi-
cally or psychologically not able to steer
an electric wheelchair.
☞To these and other possible risk
concerning your electric wheelchair
ask your doctor, therapist or special-
ist dealer.
ACCEPTANCE
All products are checked for faults in the
factory and packed in special boxes.
☞However, we request that you check
the electric wheelchair for possible
transport damage immediately on re-
ceipt – preferably in the presence of the
carrier.
☞The packaging of the electric wheel-
chair should be stored for a further
transport that might become neces-
sary.
INTENDED PURPOSE
The electric wheelchair serves to improve
independent mobility in- and outdoors.
TARGET GROUP
The target group of the electric wheelchair
includes those groups of people that do
not have sufficient independent mobility
at their disposal, to move around inde-
pendently in- and outdoors.

9
USE
Never use the electric wheelchair without
the leg supports and arm support units
mounted!
The electric wheelchair serves solely for
transporting one sitting person. – Other
pulling or transporting uses do not com-
ply with its intended purpose.
The electric wheelchair is applicable on lev-
el, firm surfaces and can be used as follows:
– for indoors (e.g. apartment, day care),
– outdoors (e.g. paved paths in parks).
– Never expose the electric wheelchair to
extreme temperatures and damaging
environmental conditions, such as sun-
light, extreme cold or salty water.
– Sand and other dirt particles can seize
on moving parts and render them with-
out function.
The electric wheelchair offers manifold ad-
justment possibilities to individual vital sta-
tistics.
National regulations might prevent the use
on busses, trains or in aircraft.
☞Inform yourself at the transportation
companies concerning limitations.
☞Before going on a flight clarify the spe-
cific transport conditions with your
flight agency and also the legal regula-
tions concerning transport in a plane in
your country of residence as well as at
your destination.
Only apply the electric wheelchair within
the scope of the specifications and limita-
tion described in chapter Technical data on
page 53.
ADJUSTMENT
Always have adaptation, adjustment or re-
pair work carried out by a specialist dealer.
The electric wheelchair offers manifold ad-
justment possibilities to individual vital sta-
tistics. Before first use an adaptation of the
electric wheelchair and a practical instruc-
tion in the functionalities of your electric
wheelchair should be carried out by your
specialist dealer. The adaptation will take
into account the driving experience, the
physical limits of the user and the main
place of use of the electric wheelchair. Be-
fore first use, check the functionality of your
electric wheelchair.
Should your specialist dealer carry out a
revision/reconditioning or make funda-
mental changes to your electric wheelchair,
without the use of original spare parts, this
under certain conditions may result in a re-
marketing of your electric wheelchair. This
will further entail that your specialist dealer
might need to conduct new conformity as-
sessments and tests.
☞We recommend a regular inspection
of the electric wheelchair adjustment
in order to ensure a long-term optimal
provision even with changing illness/
handicap patterns of the user. Especial-
ly for juveniles an adjustment every 6
months is recommendable.
☞We recommend regular medical exam-
inations for independent determination
of the user ability.

Battery voltage
The battery indicator [1] displays the battery
voltage after the system test when the driv-
ing module has been switched on.
Less LED segments of the battery gauge are
lit as the battery voltage reduces.
Battery gauge
The battery gauge [1] displays the existing
battery voltage as follows:
The colours mean:
Green Batteries charged
☞The charging status corre-
sponds to the number of
green lit LEDs.
Yellow Recharging recommended.
Red Recharge batteries immedi-
ately.
☞An accurate battery indication is only
given during travel on a level surface.
☞Uphill/downhill driving can causes
an inaccurate indication.
Evaluation
The exactness of the battery gauge de-
pends for example on the temperature, age
and strain on the batteries is therefore sub-
ject to certain restrictions.

driving situations in which you do not feel
confident/safe (e.g. driving in confined
spaces, or similar).
☞The final speed is to be preselected in
dependence on the personal impres-
sion of the respective driving situation!
☞When driving on ramps, hills or slopes
the speed is to be adjusted to the in-
clination appropriately. Never exceed
the permitted max speed. – Danger of
