quired.
Alternatively users with visual impairments
can have the documentation read out by a
helper.
Inform yourself regularly about product
safety and possible recalls of our products
in the < Information center > on our website:
< www.meyra.com >.
We have developed a product that fulfils
the technical and legal requirements of
medical devices. For information about a se-
vere accident that can still not be ruled out
completely, please use our E-mail address
< [email protected] > and inform the respon-
sible governmental agency of your country.
LIST OF MODELS

INDICATIONS /
CONTRAINDICATIONS
In case of allergic reactions, skin rashes
and/or pressure sores during the use of
the wheelchair sores contact a doctor im-
mediately.
In order to prevent contact allergies, we
recommend to use the wheelchair only
when wearing clothes.
The wheelchair serves as support in case of
extremely pronounced walking disability
resp. inability to walk, e.g. caused by:
– paralysis,
– defects or deformations of limbs,
– loss of limbs,
– damages or contractures in joints,

6
– other diseases (severe to fully pro-
nounced impairments in mobility/
walking in cases of structural an/or
functional damages of the lower ex-
tremities, u. o. amputations, results of
injuries, musculoskeletal/neuromuscu-
loskeletal caused movement disorders).
The wheelchair may not be used with a dis-
ability to sit.
The wheelchair may not be used without an
accompanying person, in cases of:
– uncontrolled balance disorders,
– cognition disorders,
– loss of extremities on both arms,
– contractures / damages of the joints on
both arms,
– insufficient or no eyesight.
☞Please ask your doctor, therapist or
specialist dealer to these and possi-
ble other risks in combination with
this product.
ACCEPTANCE
All products are checked for faults in the
factory and packed in special boxes.
☞However, we request that you check
the wheelchair for possible transport
damage immediately on receipt – pref-
erably in the presence of the carrier.
☞The packaging of the wheelchair
should be stored for a further transport
that might become necessary.
INTENDED PURPOSE
The wheelchair serves for independent
mobility of a grown up person, or transport
with help of an accompanying person.
USE
Do not reach into the spokes or grip the
tyres of the rotating wheels. – Danger of
injury!
Do not reach into the space between the
pressure brake and the tyre when propel-
ling the wheelchair. – Danger of injury!
Avoid a jerky propulsion of your wheel-
chair. – Danger of tipping over or tilting!
Do not use the wheelchair without leg
support and arm support!
The wheelchair is applicable on level, firm
surfaces and can be used as follows:
– for indoors (e.g. apartment, day care),
– outdoors (e.g. paved paths in parks),
– as a companion on tours (e.g. in a bus
or train),
☞In specific dimensions (overall
height, overall width, overall length,
turning radius) your wheelchair is
not suited for transport within a
train.
☞Get information on possible limita-
tions before the transport.
– transport within an airplane should
only be done with PU-tyres.
☞Ask the airline for possible limita-
tions before transport in an airplane.
– Never expose the wheelchair to ex-
treme temperatures and damaging
environmental conditions, such as sun-
light, extreme cold or salty water.

7
– Sand and other dirt particles can seize
on moving parts and render them with-
out function.
– Use only the handrims on the drive
wheels to propel your wheelchair.
You must not let yourself be carried in your
wheelchair by having the wheelchair lifted
from the floor. Parts that are not securely
fixed, e.g. height adjustable push handles
or clothes guard, can come away and thus
cause an accident.
Only apply the wheelchair within the
scope of the specifications and limitation
described in chapter Technical data on
page 35.
WHEELCHAIR FOLDING/
UNFOLDING/CARRYING
You wheelchair model 1.156 can be folded
without the aid of tools.
☞Observe possible jamming points in
the area of the crossbrace of the seat
and the two seat tubes!
1. Remove the seat cushion, if applicable.
2. Fold up the footboard.
3. Pull the seat belt upward in the centre
of the front and back.
☞When using auxiliary drives (wheel
hub drives) tilt the wheelchair over
one side while folding.
Your wheelchair can be carried without dif-
ficulty when folded.
For this, push one lower arm from the front
under the upward folded seat belt. Place
other hand underneath the rear seat fold for
support.
Lift the wheelchair to horizontal position.
Tip the wheelchair slightly to one side in
order to make the unfolding easier. At the
side resting on the floor, press the seat tube
down to the end stop.
☞You may need to press down both seat
tubes with the hands in order to do this.
☞Ensure that the seat tube sits securely
on the support surface.
ADJUSTMENT
Always have adaptation, adjustment or re-
pair work carried out by a specialist dealer.
The wheelchair offers manifold adjustment
possibilities to individual vital statistics. Be-
fore first use an adaptation of the wheel-
chair and a practical instruction in the
functionalities of your 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 wheelchair.
Before first use, check the functionality of
your wheelchair.
☞We recommend a regular control if
the wheelchair adjustment in order to
ensure a long-term optimal provision
even with changing illness/handicap
patterns of the user. Especially for juve-
niles an adjustment every 6 months is
recommendable.

COMBINATION WITH MAN-
UFACTURER FOREIGN
PRODUCTS
Any combination of your wheelchair with
components not supplied by us generally
results in an amendment to your wheel-
chair. Please inquire with us if there is a valid
combination clearance/release.
Auxiliary drives
Mounting of additional- and front attach-
ment drives constitute an extreme amend-
ment of the wheelchair. The amendment
will result in a forfeiture of the declaration of
conformity for the wheelchair.
☞The verification of conformity in combi-
nation with the valid medical device di-
rective / medical device ordinance lies
in the responsibility of the supplier of
the additional or header drive. He is also
responsible for the product included
documentation of the medical product
combination.
REINSTALLMENT
The wheelchair is suited for reinstallment.
With the building block system the wheel-
chair can be fit to accommodate different
handicaps body sizes. Before reimplemen-
tation the wheelchair is to undergo a com-
plete inspection.
☞Hygienical measures required for rein-
stallment are to be carried out accord-
ing to a validated hygienic plan and
must include disinfection.
The service manual, intended for the spe-
cialist dealer provides information to the re-
installment and reinstallment frequency of
your wheelchair.
LIFE SPAN
We expect an average life span of about
4 years for this wheelchair, as far as the
wheelchair is applied for its designated
purpose and all maintenance and service
guidelines. The life span of your wheelchair
depends upon the frequency of use, the ap-
plication environment and care. The imple-
mentation of spare parts can prolong the
life span of the wheelchair. As a rule spare
parts are available up to 5 years after pro-
duction is discontinued.
☞The indicated lifespan does not consti-
tute additional guarantee.

BRAKE
Arrange an immediate repair of the brakes
by your specialist workshop if the braking
performance reduces.

for longer periods of time, should be put
away safely without activated pressure
brakes, since otherwise permanent defor-
mations to the tyre surface could occur.
By locking the brakes with the brake lever
(1), the wheelchair is secured against rolling
away unintentionally (parking brake).
