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 your wheelchair
permits application in situations with ex-
treme to fully pronounced limitations in
mobility/walking in case of structural and/
or functional damages to the lower extremi-
ties (u.o. amputation, after-effects of injuries,
musculoskeletal/neuromusculoskeletally
caused motion disorders e.g. through:
– paralysis,
– loss of limbs (leg amputation),
– defective/deformed limbs,
– joint contractures/-damages,
– other diseases.
Also to be observed for individual provision
are the physical and psychological state,
age of the handicapped person as well as
the personal living condition and private
environment.
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 one of the models
shown in the list of models.
The electric wheelchair may not be used in
cases of:
– Cognitive limitations and mental re-
tarding, that rule out the independent
use of the electric wheelchair.
– Limited eyesight, which cannot be
compensated through glasses or other
aids and that lead to limitations in the
day to day.
– Influence of impairing medications (ask
your doctor or pharmacist).
– Circumstances that prevent the individ-
ual use of the control device.
– Extreme limitations in balance and/or
disorders in perception.
– Disability to sit.
☞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 outdoors.

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 51.
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 electronic 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 exams
in order to ensure safety for active par-
ticipation in traffic.
