1. GENERAL REFERENCES
1.1 Preamble
Mio will be your child’s reliable companion in their
everyday life. For this purpose, your child has to
familiarise with the wheelchair because, as any
other technical device, it may hold manifold dan-
gers if used inappropriately.
The following user manual is divided up into 5
function-specific chapters: 1. Preamble, 2. Safe-
ty Instructions, 3. Adjustments, 4. Handling, 5.
Maintenance. Chapters 6-8 discuss technical data
and warranty conditions.
Chapters 2 and 4 are supposed to acquaint you
and your child with the wheelchair and to explain
the daily handling. Chapter 3 is directed EXCLU-
SIVELY to your rehabilitation engineer since this
chapter deals unexceptionally with safety relevant
points. So please, in your own interest, leave the
adjustments to a qualified medical supply store.
Looking back on our long-standing experience
as one of the leading manufacturers in child-
hood rehabilitation, we work most carefully and
thoroughly during all stages of development and
construction. This enables us to guarantee you
the highest standard of quality, individuality and
safety. Through our certification according to ISO
9001:2008 we commit ourselves to continuously
extend this quality standard.
All materials used for the wheelchair are flame re-
sistant.
For reasons of simplification, in the following
chapters we will only refer to you; however the
information given is all the more important for
your child since it contains important safety ins-
tructions.
ATTENTION
As the current owner of the wheelchair, please
keep this manual in a safe place and make sure
all work done on your wheelchair by your medical
supply store is documented in detail in the res-
pective chapter at the end of this manual.
In case of a reuse of the wheelchair, this ma-
nual serves as an important source of informa-
tion for your health insurance fund. Additionally,
it provides the verification of regular inspections,
which might be important in the event of warran-
ty claim.
Therefore, please keep this manual with the
wheelchair and hand it back to your health insu-
rance in case of return of your Mio.
PLEASE NOTE
This user manual is intended for both you and
your rehabilitation engineer. It contains instruc-
tions on the correct adjustment of the medical aid
which may exclusively be conducted by a quali-
fied member of the specialised trade (cf. chapter
3).
Moreover, it is supposed to help you get ac-
quainted with the handling of your new Mio and
to avoid accidents (cf. chapter 4). This manual co-
vers all possible equipment options that might be
installed on a Mio and thus may contain chapters
that do not conform to your particular configurati-
on.
ATTENTION
Please read and mind this user manual with its
general safety instructions carefully before putting
Mio into service for the first time.
If you have any questions, the sanitary trade
of your confidence or our competent team will be
glad to help you.

2. Safety instructions
2.1 General Security Advice
Please make sure to read this user manual and
the safety instructions very carefully before taking
your new Mio into service. It is of utmost impor-
tance that both the user and their assistant are
able to both understand and realise all instruc-
tions. Since it is not possible to list all dangers
that may possibly occur under different circum-
stances, please make good use of caution and
mind whenever you are using your wheelchair!
Please use Mio exclusively according to the
specifications described in chapters 1.3 and 1.4.
If used otherwise and/or inappropriately, the
wheelchair may considerably endanger you and
your surroundings. Furthermore, this may lead to
the expiry of our guarantee and product liability!
Please make yourself and your child acquain-
ted with the respective functions, specific charac-
teristics, and the operation of your wheelchair.
Take sufficient time for this and please make su-
re to conduct your first driving practices with the
support of an experienced assistant.
It is very important that – in the presence of
an experienced assistant – you test the stability of
your new wheelchair to both sides, to the front,
and to the back. To do this, please slowly lean as
far as you can to each side, front, and back while
sitting in your wheelchair in order to, for instance,
pick up an object from the ground. Attentively ob-
serve when exactly the wheelchair starts tipping
over and memorize this point well.
To keep your wheelchair permanently safe and
functional, please consider the instructions on
handling (chapter 4) and maintenance (chapter
5).
Do not ever leave your wheelchair unattended
– neither empty nor occupied! The brakes might
loosen unintentionally and endanger you, your
child, and your surroundings considerably. Always
position your wheelchair against a wall or a cor-
ner so it cannot roll away.
Please do not by any means conduct adjust-
ments, maintenance and/or repair work by your-
self, but always turn to the medical supply store
of your confidence whose trained staff has been
introduced proficiently to the conduction of this
work and is equipped with the necessary tools.
For functional reasons, your hands are placed
on rotating parts (i.e. the rear wheels) while dri-
ving your wheelchair.
To avoid injuring your hands, please make sure
not to reach into the spokes of the rear wheels
or the space between rear wheel and lever brake.
Profile wheels with integrated handrims or spoke
covers (optional devices) reduce the risk of finger
injuries.
2.2 Before every use
The functional efficiency of the locking brake
(cable brake and the brake for the assistant) is
dependent on:
• correct inflation pressure
• intact bowden wire
• non-worn-out braking bolts.
Please check the braking effect of the cable
brake before every use. The cable brake can only
function properly with sufficient air pressure and
flawless tyre profile of the rear wheels.
Check the cables of the cable brakes for da-
mages before every use. Damaged cables are to
be exchanged immediately.
Check the correct tyre inflation pressure accor-
ding to the indication on the tyre equipment. By
the way: it will be a lot easier to drive and mano-
euvre your wheelchair with the correct air pressu-
re of caster and rear wheels.
Please check the safe and firm fit of the quick-
release-axles: If the quick-release-axle button is
not pressed, the rear wheels or casters must not
be removable. The axles need to be cleaned from
dust and fluff regularly.
Please conduct a general visual inspection to
duly discover and repair possible damage that
might lead to endangerment.

2.3. How to avoid tipping
Avoid using the foot rest when getting in or
out of your wheelchair for it might tip forward. If
possible, please fold the foot rest to the side or to
the back in order to get closer to the wheelchair.
And make sure that you only conduct this action
on firm, even ground and with the locking brake
tightened.
Under certain circumstances it might
be therapeutically necessary that the child
does use the foot rest to get in or out of
the wheelchair. In this case, please turn
the rear wheels forward to improve the
wheelchair’s resistance against tipping and
do not let your child get in or out without
supervision and assistance.
Practice all driving techniques on even ground
and only with the support of an experienced as-
sistant at first. Only after that should you try and
tackle downgrade and upgrade paths – again,
with the support of an experienced assistant.
Avoid putting your wheelchair into bank posi-
tions on uneven or sloping ground to prevent it
from tipping sidewards! Always drive in right ang-
le from the hillside/the obstacle, never diagonally.
Please avoid extreme adjustments of your
wheelchair with a high seat inclination and place
the seat back as far at the front as possible to
gain safety from tipping. Extreme configura-
tions combined with a disadvantageous posture
may provoke the wheelchair to tip, even on level
ground.
Please drive downgrade or upgrade paths ex-
clusively with the anti-tipper feature activated.
When driving on upgrade paths and offsets, bend
the upper part of your body forward as far as pos-
sible and drive ramps and upgrades with a pitch
or incline of more than 7° (12%) only with the
support of an assistant. When driving downgrade
paths, please bend your upper body as much to
the back as possible.
Adjusting the casters incorrectly or driving
too fast (especially on downgrade paths) may
lead the casters to judder, which may result in a
dangerous and abrupt braking of the wheelchair.
Hence, do not change the pre-adjusted position
of the casters in the caster fork, drive downgrade
paths very slowly and bend the upper part of your
body backwards while doing so.
In order to reach for objects on the sides or in
front of your wheelchair, please remember your
initial stability test and do not lean out too far.
ATTENTION
The locking brake cannot usually be used
to brake during driving since this might ma-
ke your wheelchair halt abruptly with the
risk of falling out for the passenger. It is
only to be used in that way very limitedly
and only be very experienced drivers.
We strongly recommend using anti-tippers to
inexperienced and young wheelchair drivers.
Because of the body measurements specific to
the user, it might be possible that adjustments of
seat and wheel positions beyond the tipping sa-
fety limits can be realised on your wheelchair. In
this case, the safety from tipping must be valued
over the handling characteristics!
2.4 Coping with obstacles
To surmount level differences, ramps or lifts
should be used whenever possible. We strongly
advise you to surmount stairs only with the aid
of two experienced assistants. For this, the safety
wheel needs to be deactivated. Please mind that
the wheelchair may be held, carried or lifted on-
ly on metal parts which are firmly bolted to the
frame.
Please note that the rubber caps are merely
stuck to the push handles and may loosen un-
der unfavourable circumstances (heat, moisture,
etc.).
ATTENTION
Extendable push handles and/or
push bars are connected loosely to the
wheelchair and may loosen.
Do not use escalators in any case – not
even with assistants!!! Department stores and
public buildings with escalators should always
have suitable lifts available.
Do not rapidly drive towards offsets (e.g. kerb
stone edges) as this implies a heightened danger
of tipping!
Do not jump from stairs or offsets with your
wheelchair! This does not conform to the inten-
ded usage of the wheelchair, puts you and your
surroundings in serious danger, and may damage
your wheelchair heavily.
Please remember to fold your anti-tippers to

the inside while using lifts and lifting plates and
while surmounting offsets.
ATTENTION
Before pulling a person seated in a
wheelchair backwards over an obstacle via
the push handles, please check the push
handles in their bracket (stand spring) and
the rubber pads on the push handle pipes
for firm fit.
2.5 Heat and water
Handrims heat up through strong friction, es-
pecially by braking during fast driving or along
downgrade paths. Therefore, if you have sensi-
tive skin, we recommend you to wear gloves like
those used in race-cycling (with leather palm pro-
tection – but never woollen gloves) or special
wheelchair gloves.
Using the wheelchair in damp locations or in
water should be avoided, as this may lead to the
corrosion of components, which negatively af-
fects the driving quality and service life of your
wheelchair.
Textile components of the wheelchair, such
as cushion or plastic are inflammable. Therefore,
please keep any ignition sources, particularly ligh-
ted cigarettes, away from the wheelchair.
Exposed to direct solar radiation, dark sur-
faces of the wheelchair (seat, back, clothing gu-
ards, etc.) may heat up strongly. To avoid burns,
place the wheelchair in a shady place or protect
it from direct solar radiation with a blanket (or a
similar object).
2.6 Driving in road trafc
Keep in mind that as a driver/passenger in
your wheelchair you are a “participant in public
traffic” and therefore have to respect the road
traffic regulations.
Since your wheelchair does not count as mo-
tor vehicle according to legal regulations, you
may use pavements driving at walking pace.
In the dark, wear preferably light-coloured clo-
thes or clothes with reflectors. Avoid driving on
road surface or bicycle paths.
Your wheelchair is provided with reflectors on
the sides and on the back. Regularly check whe-
ther they are clean and clearly visible.
To use your wheelchair as a seat in a passen-
ger car, only use means of transportation appro-
ved for the transportation of wheelchairs.
ATTENTION
Transporting a person sitting in a
wheelchair in a vehicle implies a conside-
rable safety risk for all people involved. We
therefore strongly recommend not using
the wheelchair as a seat in a passenger car
and sitting down on a conventional car seat
instead.
During a ride in a vehicle (including pub-
lic transport), you must not be seated in your
wheelchair without a restraint system for a pas-
senger.
If using your wheelchair as a passenger se-
at in a vehicle cannot be avoided, the regulati-
ons according to DIN 75078-2 have to be fulfilled!
Please make sure to read chapters 4.10-4.12
“Transportation in a passenger car” (p.30)!

3. Adjustments
The following indications on the adjustments
of Mio affect its usage safety! Every technical
device inherits safety risks in everyday usage.
Therefore, we are pointing out explicitly that all
adjustments, reparations, and any other sorts of
changes are to be conducted exclusively by the
rehab technicians of your medical supply store
who have been qualified by us!
Otherwise, you may endanger yourself, your sur-
roundings, and especially children considerably,
and, moreover, lose our warranty claim!
ATTENTION
A wheelchair is a medical aid which must
be adjusted to the individual situation of
your child by your rehab technician in or-
der to obtain the highest therapeutic bene-
fit possible.
ATTENTION
When conducting any adjustments, ple-
ase make sure to maintain distances bet-
ween all movable parts (e.g. abduction
wedge, etc.) and fixed parts in order to pre-
vent human body parts from clamping in
between them.
Guidance values for this purpose are:
Finger area: <5mm or >25 mm
Foot area: <25 mm or >45 mm
Head area: <60 mm or > 250 mm
If no other specifications are indicated, the fol-
lowing torques are valid for screw joints:
M5: 5 Nm
M6: 7 Nm
M8: 20 Nm
M10: 25 NM
quick-release-axle fitting: 35 NM
3.1 Leg support adjustment
The leg support is ideally adjusted if the com-
plete thigh rests (with a two finger distance bet-
ween seat and hollow of knee) evenly on the se-
at cushion/shells while the leg is standing on the
foot rest in a right angle. A foot rest positioned
too high leads to a permanently buckled position
in the pelvic area. If it is adjusted too low, unple-
asant congestions in the thighs might occur.
3.1.1 Standard leg support
Adjustment of the lower leg length
• remove screws (image 1, pos. 1) and loosen
screw (image 1, pos. 3) on both sides
• place footrest (image 1, pos. 2) into desired

3.2 Seat height & seat inclination
By modifying the seat angle support, the seat
height may be altered by 4.5 cm in 1.5 cm-steps.
Usually, a strong or light seat inclination is
chosen in order to obtain a secure and comfor-
table sitting position with even distribution of the
seat pressure and to straighten up the pelvis.
(Differing adjustments may also make sense in in-
dividual cases.)

ATTENTION
When adjusting the seat height on the
front, you should always make sure that
you can access tables easily without your
knees hitting their edges. Corresponding
to the position of the foot rest, the casters
must be free to rotate 360°.
3.3 Seat width
The seat width of the wheelchair may be exten-
ded by 2 cm via the following four measures:
• setting off the angle support
• setting off the back support angle
• setting off the distance bushes
• adjusting the quick-release-axle adapter
a. Setting off the angle support
(view underneath the seat plate)

3.4 Centre of gravity
By moving the back rest (image 1, pos.
3) in the side part, the centre of gravity of the
wheelchair may be altered by up to 6.5 cm. The
seat support angles (image 2, pos. 1) on the
lower surface of the seat plate should be moved
to the same extent to maintain the ordered seat
depth. When leaving our factory, the wheelchair
is preadjusted into a tipping stable position. The
further back the back rest is mounted, the more
the wheelchair tends to tip backwards. However,
it may also be tilted back on 2 wheels more easily.
This facilitates, for experienced wheelchair users,
to quickly and easily surmount obstacles, as the
wheelchair’s agility is effectively improved.
ATTENTION
Even if the anti-tipper is activated and
there is actually no danger, a beginner may
be unsettled or even demotivated if the
wheelchair’s adjustments make it too prone
to tipping!
ATTENTION
Please work carefully, gradually, and
only with the aid of an experienced assistant
towards the maximum degree of tipping
proneness desired for by the user! Read the
SAFETY INSTRUCTIONS carefully. (p. 9 ff).
Moving the back rest
• loosen screw joints (image 1, pos. 1+2) on

3.6 Seat depth
On the three images above you can see the
state of Mio when delivered.
• Image 1: seat plate, back
• Image 2: seat plate, front
• Image 3: seat support angle, front
In this state, the seat depth may be increase
continuously by 4 cm by moving the seat plate.
Moving the seat plate
• loosen screw joints (image 3, pos. 1) on both
sides and move seat plate (image 3, pos. 2)
into the desired position
• tighten screws firmly
The seat depth may be increased further if it is
possible to move the seat support angle even
further to the front after adjusting the centre of
gravity (cf. chapter 3.4).
Moving the seat support angle
• loosen screw joints (image 3, pos. 3) on both
sides and place seat plate (image 3, pos. 2) in-
to the desired position
• tighten screw joints firmly
3.7 Back height
In order to provide as much moving space as
possible for the arms when driving the wheelchair,
the active driver’s back height should generally
reach to the bottom line of the scapulae.
The upper edge of our firm moulded backs is
pulled up by approx. 5 cm in model 3 (and ap-
prox. 2 cm in model 1). Thus a longer support of
the spine is achieved. Thanks to the curved upper
edge of the back sheet plate, however, the scapu-
lae can still be moved freely.
1.) Back, bottom, with max. seat height
2.) Back height increase max.: BH + 3 cm
3.) Back, bottom, with min. seat height
4.) Back height increase max.: BH + 7.5 cm
The back height is growable in two 3 cm steps
with max. seat height. With min. seat height, the
back height is growable in 1.5 cm steps by up to
7.5 cm.
• remove screws (pos. 1) completely on both si-
des
• mount back rest (pos. 2) into desired position
• tighten screw joints firmly
3.8 Adjustment of caster and rear
wheel
Because of its firm wheel base, Mio is free of
adjustments concerning the caster–rear wheel–
constellation.

3.9 Brake
The brakes inherit an important safety func-
tion in your Mio. Correct adjustments of the
brakes are a vital prerequisite for its readi-
ness to drive.
Each Mio is equipped with two cable brakes in the
clothing guards. They exclusively serve the purpo-
se of keeping the wheels in a rest position. They
are not designed to decelerate the wheelchair
while driving. For this purpose, the handrims, or
optionally the attendant brake, should always be
used. Please be aware that aluminium-handrims
may heat quickly due to friction.
ATTENTION
For your own safety, always check whe-
ther the brakes function correctly. Its func-
tion may be restrained by too little air pres-
sure in the tyres, moisture, worn out profile
and/or brake bolt, defective cable, and too
much distance between the brake bolts and
the tyres.
3.9. Standard brake
Brake adjustment
• check tyre air pressure of the rear wheels; in-
flate tyres to the indicated value if necessary
• if necessary, loosen screw joints of the cable
brake (image 2, pos. 1)
• adjust brakes so the distance between the
brake bolt and tyres is about 3 mm (technical
alterations reserved)
• tighten screws firmly
• for vernier adjustments, readjust the set screw
(image 2, pos. 2)
• checkfunctionwiththesecuringsupportofan
assistant
ATTENTION
On a ramp with 7° (12 %) incline, the
rear wheels of the wheelchair with passen-
ger must not slip with the locking brake
tightened.
Adjustment of the brake lever height
• loosen both screws (image 1, pos. 1)
• place brake lever into desired position via the
ball head
• retightenbothscrews

3.9.2 Attendant brake (optional)
The attendant brake can be used to decelerate
while driving, provided that the tyre air pressure
is correct and the brake bolt is not worn out (cf.
also chapter 2.3). Via an additional brake cable, it
activates the standard locking brake independent-
ly from the driver.
The adjustment follows the same instructions
as for the standard brake described in chapter
3.9.1 Brake, standard.
ATTENTION
In the second indexed position of the
hand brake lever (B), the brake must be
firm enough to ensure that the rear wheels
of the wheelchair with passenger do not
slip on a 7° (12%) incline (see above).
To lock firmly, the latch lever (C) has to snap
into the brake lever (B). To unlock, please pull the
brake lever further which will release the latch le-
ver automatically.
ATTENTION
Please mind that signs of wear may oc-
cur on the brake bolt. So please check the
functional efficiency of your brake befo-
re each ride and have your brake bolt ex-
changed if necessary.
Please handle the tyre profile in the same way,
for it, too, may wear increasingly under the influ-
ence of the attendant brake.
3.10 Anti-tippers
The anti-tippers prevent your wheelchair tip-
ping backwards unintentionally. Correct adjust-
ments are hence very important for the function
of the anti-tipper. The correct distance to the
ground is 2-5 cm.
ATTENTION
Please also read the respective chapters
of the SAFETY INSTRUCTIONS.
• measure current distance between the anti-
tipper and the ground
• remove rear wheels
• remove screw joints (image 2, pos. 1+2) com-
pletely and insert them into suitable bores
• retighten screw joints (image 2, pos 1.)
• twist screw nuts (image 2, pos. 2) as far on
the screws so they protrude min. 1 mm from
the screw nuts
• check distance to the ground
• check function with securing support of an as-
sistant

Further adjustments can be done via the small
wheel at the back of the anti-tipper.
• loosen screws (image 1, pos. 1) on both sides
• remove screws (image 1, pos. 2) on both sides
• choose among the three holes and insert
screws (pos. 2)
• retightenallscrews
ATTENTION
Make sure to make the same changes of
the anti-tippers on both sides!
3.11 Head rest (optional)
Our head rests may be adjusted in height,
depth and angle.
Adjustment in height:
• loosen the control lever (image 2, pos. 1) and
set it tight after reaching the desired position
• Adjustment in depth: loosen the star knob
(image 2, pos. 2) and set it tight after re-
aching the desired position
• Adjustment in angle: loosen the three
screws (image 2, pos. 3) slightly and tighten
them after reaching the desired position
