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

independent mobility indoors and out-
doors.
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.

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 checks
for independent determination of the
driving ability.
