5 Introduction
Before starting your first journey, familiarise
yourself with these usage instructions, paying
particular attention to all of the safety infor-
mation and hazard warnings contained in
them.
Allow your therapists and doctors to advise
you, your carers, and assistants on how to use
the product and what you are safe to do with
the product based on your current ability. Clari-
fy with them as well which wheelchair tech-
niques you can learn on the basis of your abil-
ity.
Under no circumstances should you do
anything with or in the product that you have
not learned to do and have not mastered.
You, your carers, and assistants should also
seek advice from your therapists and doctors
as well as the rehabilitation specialist dealer
about the use and settings of your product and
all the safety accessories available (e.g., anti-
tipping supports and lap belt).
You should always heed the advice pro-
vided by doctors, therapists and the rehabilita-
tion specialist dealer on the necessary safety
accessories.
If you are not sure how to handle the
product or if technical faults occur, please con-
tact your rehabilitation specialist dealer or
PRO ACTIV before using it.
Never leave the product unattended.
Secure the product against unauthorised
use and theft.
When combining your product with
equipment made by other manufacturers (e.g.
seat cushion, drive devices, etc.), make sure
that the serviceability of the individual compo-
nents and the unit made up of them is ensured.
You can get information on the suitability of a
combination from the manufacturer of the third-
party components or from your rehabilitation
specialist retailer.
The product contains small parts that may
pose a choking hazard for children.
6 Purpose and indication
This product offers children and young people
who have difficulty walking or cannot walk the
option to replace walking with driving, using a
muscle-powered wheelchair to a technically
feasible extent. The objective is to maintain or
increase the greatest possible independent
mobility and to integrate the active wheelchair
user in everyday life.
Indications: Walking impediment or limited
ability to walk due to paralysis, limb loss, limb
defect/deformation, joint contractions/joint
damage, neurological and muscular diseases.

Usage instructions BUDDY 4all & classic

Contraindications: Some wheelchair options
are unsuitable for certain disease profiles or
handicaps. A suitable selection will be made by
the therapist/doctor/rehabilitation specialist
dealer during the consultation.
In addition - for safety reasons - the product
may only be operated by people who
 can move and coordinate their hands and
arms so that they are able to operate all
control elements without restrictions while
using the wheelchair.
 are physically and mentally capable and
have the visual ability to safely operate the
product in all operating situations and can
meet the legal requirements for use on
public roads. For children or people with
mental, significant motor or visual impair-
ments, the attendants can ensure the re-
quired traffic safety as a substitute and as
a companion.
 Who have been trained in its use by the
rehabilitation specialist dealer or
PRO ACTIV.
7 Proper use
This wheelchair for children and young people
is designed for use on level and solid surfaces
indoors and outdoors. Avoid driving on un-
paved or loose surfaces (e.g. on loose gravel,
in sand, mud, snow, ice or through deep pud-
dles of water, and under poor weather condi-
tions (e.g. storms), as this may result in incal-
culable risks. Thanks to its special design fea-
tures, the BUDDY can be adjusted in width as
the child grows and, in addition to a wide range
of adjustment options, the “growing feature”
offers optimum adaptation to the individual
needs and size of the user by simply replacing
individual components.
The maximum permitted load of the product in
its standard design is 100 kg. Individual cus-
tomisations can be designed for a higher load;
this is then indicated on the rating plate.
Please note that the load limit indicated on the
rating plate may not be exceeded even when
transporting objects and carrying out strength
exercises in the product.
Note that the maximum load weight is reduced
accordingly when mounting components with
lower load limits on the product, e.g. drive
wheels with few spokes.
Proper use of the product is a basic require-
ment of safe operation. The product may gen-
erally be used only for applications that are
listed and described in these usage instruc-
tions. This includes storage, transport, mainte-
nance/inspection, and repair, as well as the
safety information in each chapter of these
usage instructions.

10 Commissioning and handover
The product will be handed over to you ready
for use by a rehabilitation specialist dealer or a
field representative or by a product consultant
from PRO ACTIV.
You will be fully instructed in the use of the
product based on the usage instructions in-
cluded in the delivery. You will be handed over
a record of training and handover certificate as
written proof. In addition, you will be handed
the usage instructions and, if necessary, fur-
ther accessories for your own use. It is rec-
ommended that you take along an assistant to
the training so that, if required, they can assist
you later when handling the product.
During the hand-over, the record of training
(chapter 38) and the hand-over certificate in-
cluding the associated check list (chapter 39)
must be filled in. The rehabilitation specialist
dealer should send the completed documents
to PRO ACTIV for filing as a file by e-mail or in
the form of a copy by fax or in the post.
11 Introduction to the product & the
surroundings
During the initial commissioning of the product,
drive at minimum speed and become accus-
tomed to the driving characteristics of the
product. Always adapt the speed and driving
manoeuvres to match your own abilities and
external circumstances. You will get a feel for
how to use the product safely after a short
time. Before driving up or down slopes or hills
with the product, you should be proficient in the
safe handling of the product on level ground.
Practice bending over, gripping, stretching and
getting out, until you know the limits of your
abilities. Allow yourself to be assisted until you
know what can cause falls or tips and how to
avoid it.
Get to know the environment in which you wish
to use the product. Look out for obstacles and
learn how to overcome or avoid them.
12 Safety instructions – prior to
driving/use
When getting into the wheelchair, do not
tread on the footrests as this may tip the chair
over.
Before every trip, check the condition of
the wheels (e.g. visual inspection of the spokes
and rims, check the tyres for damage, foreign
bodies and crack formation). If you have any
doubts about the serviceability of the product,
stop using it.
Check the tyre pressures at regular inter-
vals. Ensure that you comply with the manu-
facturer's specifications which can be found on
the tyres. If the tyre pressure is too low, the
optimum functional capability of the knee lever
brake is not guaranteed, and an excessively
low tyre pressure influences the driving behav-
iour. Apart from that, there is an increased risk
of a flat tyre.
Before starting out, check that the
product's brake works. If all existing brakes are
not fully functional, no trips may be taken.
Check the stable condition of the seat
and back system at regular intervals and in
case of doubt, have your rehabilitation special-
ist dealer assess its condition.
Always ensure that your feet cannot slip
off the footplate support when using the prod-
uct.
Before using the product, ensure that the
anti-tipping supports are in the operating posi-
tion and are functional.
Due to environmental effects, it is possi-
ble that the properties and therefore secure
attachment of the push handle covers may
change detrimentally. For this reason, it is
important to check that the handles are tightly
fitted and fixed in position prior to use. If this
should no longer be the case, then the push
handles may not be used until they have been
fixed.

Usage instructions BUDDY 4all & classic
10
Before each use of the product, make
sure that the anti-tipping supports and push
handles are firmly attached and the quick-
release axles on the caster and drive wheels
are also securely locked in place.
Depending on the equipment, the product
may have folding/closing mechanisms that
pose a risk of crushing injuries (e.g. pinching
your fingers). For this reason, please allow
your rehabilitation specialist dealer to explain
how to work these mechanisms and then have
a go yourself under instruction.
If required, you can have your product
equipped with a suitable chest or lap belt.
Please make sure that the belt is set up so that
it does not have any negative impact on
breathing, does not strangle you should you
fall or tip out of the product and which you can
easily remove yourself.
Make sure that the passive illumination
(reflectors) are always on your product, are in
perfect condition and are clearly visible.
When travelling, always carry a repair kit
and tyre pump for repairs in event of punc-
tured/flat tyre. An alternative to this is an
emergency puncture repair spray that fills your
tyre with a foam that hardens in the tyre.
13 Safety instructions –
while driving/using
Note that some parts of your product can
become extremely hot at high ambient temper-
atures (e.g. sauna). This means that above
50°C, the product may be damaged and above
40°C there is already the risk of burns for the
user, which should not be underestimated,
particularly for people with impaired sensitivity.
For this reason, the product should not be
exposed to such extreme temperatures.
PRO ACTIV cannot accept any liability or pro-
vide any warranty for personal injury and mate-
rial damage caused by such stresses.
There are also certain risks that exist at ex-
tremely low temperatures, which must be min-
imised by wearing appropriately insulating
clothes, for example.
You may only drive on slopes where the
product can be safely controlled with the
handrims. Never drive the product on slopes of
more than 10 %.
When driving in curves, reduce your
speed to a minimum and if possible, lean your
upper body towards the curve.
Do not ride parallel to slopes and inclina-
tions due to the risk of tipping.
Do not stop on a steep slope, otherwise
there is a risk of losing control of the product. If
possible, do not turn on a slope or change your
direction.
Note that the knee lever brake and the
integrated brake are parking brakes that may
only be applied when the product is at a stand-
still. These are not service brakes that are
suitable for reducing speed.
Do not attach objects (carrier bags, etc.)
to the product.
When driving in areas that are approved
for pedestrians, keep to the maximum permit-
ted speed (walking speed 6 km/h) and main-
tain sufficient lateral distance (at least the
width of a wheelchair) from obstacles and oth-
er road users.
Avoid driving on unpaved or loose sur-
faces (e.g. on loose gravel, in sand, mud,
snow, ice or through deep puddles of water).
When travelling on poorly maintained
paths (e.g. coarse gravel, potholes), there is an
increased risk of puncturing your tyres as well
as tipping.
When travelling on poorly maintained
paths with potholes and loose stones, drive
carefully to prevent the caster wheels from
blocking.

Usage instructions BUDDY 4all & classic
11
The product can affect other devices, for
example theft protection barriers in department
stores.
The product is only intended for transport-
ing one person with limited mobility and must
not be used for any other purpose, e.g. for
transporting goods.
When reversing, the anti-tipping supports
should always be used as there is an in-
creased risk of tipping over. If this is not possi-
ble, then ask other people to help ensure that
there is no risk of tipping over.
The product may only be propelled using
the handrims. If you propel the chair with the
tyres (thumbs or fingers on the tread of the
tyre), there is the risk of crushing or otherwise
injuring fingers and thumbs.
Do not reach into the area of the spokes
or other tight spaces in the area of the wheels.
There is an increased risk of being injured
here, particularly while in motion. If you have
limited coordination of your limbs, then you
should cover the spokes with a spoke shield,
for example, to minimise the risks.
Smoking when using the wheelchair
should be forgone, as the seat and back sys-
tem may be damaged due to dropping ash.
14 Safety instructions regarding
obstacles
Driving on steps with the product is for-
bidden.
Due to the significantly high risk of tipping
and injury, the product should only be used to
negotiate escalators after participation in a
corresponding safety training course and with
an accompanying person for safety reasons.
The maximum obstacle height which can
be negotiated is 10 cm.
When driving over or passing obstacles, it
is important that you avoid any product or body
parts catching on the obstacle as this may lead
to falls causing serious injuries to the user and
third parties as well as damage to the product.
Always drive over curbs or other obsta-
cles so that you cross them to the front or at
right angles and at the minimum required
speed. When approaching an obstacle at an
angle or driving over it with just one wheelchair
wheel, there is an increased risk of tipping over
sideways.
If the product with the user needs to be
transported over an obstacle and there are
suitable facilities such as a ramp or a lift avail-
able, then these should be used. If such facili-
ties are not available, then the obstacle is to be
overcome by being carried by two helpers.
When carrying the product, it may not be lifted
by the side sections, the drive wheels or the
footrests. We recommend holding the product
on the frame and the back cross bar to carry it.
Before crossing an obstacle (steps,
thresholds, etc.), the anti-tipping supports must
be swivelled from the operating to the passive
position or removed so that you do not make
contact with the obstacle when crossing, re-
sulting in your falling. After crossing the obsta-
cle, the anti-tipping supports must be immedi-
ately returned to the operating position (Chap-
ter 24).
For overcoming obstacles such as kerbs
or steps, the product needs to be actively
tipped. The caster wheel may otherwise jam at
right angles to the obstacle and could block.
This could damage the caster wheel or the
caster fork and result in injury to the user. If
actively tipping it is not possible, then the ob-
stacle should not be approached or you need
to request assistance from an accompanying
person. Particular attention needs to be paid to
this when using an auxiliary drive.

15 Safety instructions regarding
dangerous locations and
dangerous situations
The operator of the product determines the
route to be driven themselves, taking the us-
age instructions, their driving knowledge, and
physical abilities into consideration.
Personal driving skills are particularly important
in the following dangerous locations that are
provided as examples; the product user must
use their judgement before driving in such
locations:
 quay walls, landing and berthing locations,
paths and locations close to water, unse-
cured bridges and dykes.
 narrow paths, slopes (e.g. ramps and
driveways), narrow paths on a slope,
mountainous routes.
 narrow and/or steeply sloping paths along
main roads or near cliffs.
 routes that are covered in leaves, snow or
ice.
 ramps and lifting equipment on vehicles.
When driving in a curve or turning on hills
or downward slopes, there may be an in-
creased tendency to tip over to the side due to
the changes in the centre of gravity. Avoid
such driving manoeuvres. If these cannot be
avoided, perform these driving manoeuvres
with increased caution and only at a very slow
speed. If necessary, the driving manoeuvre
must not be performed or only with the help of
an assistant.
Use particular caution when approaching
stairs, edges, drops or other hazard areas.
Extreme caution is needed when crossing
main roads, intersections and level crossings.
Rails in the road or level crossings must never
be crossed when travelling parallel to them, as
otherwise the wheels could become caught
which would result in the product being unable
to manoeuvre.
Extreme caution is needed when driving
on ramps and lifting equipment on vehicles.
Ensure in advance that the ramp is wide
enough so that you do not risk the product
wheels slipping off the ramp. When lifting or
lowering a ramp or lifting equipment, the park-
ing brake of the product should be applied.
Always keep the product in the middle of the
ramp.
The grip of the tyres on the ground is
reduced under wet conditions. There is an
increased risk of slipping. Adjust your driving,
braking and steering behaviour accordingly.
16 Safety instructions – after
driving/use
Apply the parking brake before getting out
of the product.
When getting out of the wheelchair, do
not tread on the footrest due to the risk of tip-
ping over.
17 Individual setting options
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
17.1 Adapting the seat height at the
back
The product is equipped with a wheel plate,
which enables seat height adjustment. The
product is generally equipped with a 2-slot
wheel plate. With this equipment, the seat
height can be adjusted at the rear by a total of
6 cm.

Figure 2: 2-slot wheel plate for rear seat height
adjustment (view from inner side of product)
In order to adjust the seat height at the rear,
first remove the drive wheels via the quick
release axles (see chapter 21.1), so that you
have direct access to the wheel plates. Now,
there are the following options.
17.1.1 Mounting the drive wheel bushing
in the other wheel plate slot
 If the drive wheel bushing is initially
mounted in the lower slot of the wheel
plate, the rear seat height can be reduced
by 3 cm by mounting it in the upper slot.
 If the drive wheel bushing is initially
mounted in the upper slot of the wheel
plate, the rear seat height can be in-
creased by 3 cm by mounting it in the
lower slot.

3. On each side, screw the inner steel locking
nuts onto the drive wheel bushing and fi-
nally tighten the inner steel locking nuts
(AF 30 mm) on the right and left to 70 Nm.
17.1.2 Turning the wheel plate by 180°
The wheel plate slots are worked eccentrically,
so that by turning the wheel plate by 180°, a
reduction of the seat height by approx.
1 cm is achieved.
Figure 6: Changing the seat height at the rear by
rotating the wheel plate by 180°.
Figure 7: M6 fixing screws on the wheel plate (view
from outer side of product, drive wheel removed)
Figure 8: M6 nuts of the wheel plate (view from the
inner side of the product)
1. Remove the wheel plates on both sides by
unscrewing the four M6 fixing screws (AF
5 mm) with the M6 nuts (AF 10 mm).
2. Then turn the wheel plate by 180° and
position it behind the same frame holes as
before. Ensure that you mount the track
spacers and the camber wedges (between
the frame and the wheel plate, see Fig. 8)
exactly as they were installed ex-factory
upon delivery (they must not be rotated
with the wheel plate). In addition, the wheel
plate can be mounted ex-factory on the in-
side or outside of the frame. Again, make
sure that you re-mount the wheel plates as
they were ex-factory upon delivery.
3. Now reattach the M6 fixing screws (AF
5 mm) with M6 nuts (AF 10 mm) and tight-
en them to 7 Nm. Ensure that both wash-
ers are reinstalled on each screw.
4. Then the drive wheel bushing is mounted
in the other slot. Observe the instructions
in Chapter 17.1.1.
17.1.3 Mounting the wheel plate in the
other frame holes
 If the wheel plate is mounted in the initial
position in the lower frame holes, the seat
height can be reduced by 2 cm by mount-
ing it in the upper frame holes.
 If the wheel plate is mounted in the initial
position in the upper frame holes, the rear
seat height can be increased by 2 cm by
mounting it in the lower frame holes.

17.1.4 Summary
Figure 11: Example of initial position for adjustment
For the seat height adjustment, as in the initial
position shown in the previous figure, the fol-
lowing steps can be taken:
1 cm reduction of the rear seat height: Rota-
tion of the wheel plate by 180° & moving the
drive wheel bushing back into the lower wheel
plate slot
2 cm reduction of the rear seat height: Mov-
ing of the wheel plate into the upper frame
holes
3 cm reduction of the rear seat height: Mov-
ing of the drive wheel bushing into the upper
slot of the wheel plate
4 cm reduction of the rear seat height: Rota-
tion of the wheel plate by 180° (drive wheel
bushing remains in the upper wheel plate slot)
5 cm reduction of the rear seat height: Mov-
ing of the wheel plate into the upper frame
holes & moving of the drive wheel bushing into
the upper wheel plate slot
6 cm reduction of the rear seat height: Rota-
tion of the wheel plate by 180° & moving of the
wheel plate into the upper frame holes (drive
wheel bushing remains in the upper wheel
plate slot)
If the wheel plate is initially mounted in the
upper frame holes and/or the drive wheel
bushing is mounted in the upper slot, the seat
height can also be raised.
In addition to the 2-slot wheel plate, a 1-slot
wheel plate is also available. The adjustment
options are more limited with this wheel plate.
The following applies:
 Max. seat height adjustment, with a 22”
drive wheel and 21 cm frame height is ap-
prox. 36 cm
 Max. seat height adjustment, with a 24”
drive wheel and 21 cm frame height is ap-
prox. 38 cm.

17.1.5 General instructions
When changing the rear seat height each time:
 the brakes must be readjusted (see Chap-
ter 25).
 the caster wheel axles must be readjusted
(see Chapter 22.4).
 the backrest angle may have to be reposi-
tioned (see Chapter 18.1).
 make sure that there is sufficient ground
clearance under the footrest. Experience
shows that this should not be less than 4
cm (see Chapter 23).
17.2 Adjusting the seat height at the
front / angle of seat
If the seat height has to be adjusted, the angle
of the seat or the front seat height can be ad-
justed. This setting is carried out via the posi-
tion of the caster wheels in the caster wheel
fork and the caster fork size.
17.2.1 Adapting by positioning the caster
wheels in the caster fork
Adjusting the front seat height or angle of seat
can be carried out via the positioning of the
caster wheel in the caster fork. Generally, the
caster forks have three possible positions that
can be used to change the front seat height in
steps of 15 mm.
 If the seat inclination or the front seat
height are to be increased, the caster
wheel is mounted in a lower position in the
caster fork.
 If the seat inclination or the front seat
height are to be reduced, the caster wheel
is mounted in a higher position in the cast-
er fork.
Figure 13: Three positions in the caster fork for
positioning the caster wheel and its effect on the
front seat height
The instructions for disassembly and assembly
of the caster wheels can be found in Chapter
22.1.
17.2.2 Adaptation by replacing the caster
fork
If the adjustment range of the existing caster
fork is insufficient, the next larger or smaller
one can be used.
In doing so, the bottom position of the fork size
1 is equivalent to the top position of fork size 2
and the bottom position of fork size 2 to the top
position of fork size 3.

17.2.3 General instructions
When changing the angle of seat or front seat
height each time:
 the caster wheel axles must be readjusted
(see Chapter 22.4).
 the backrest angle may have to be reposi-
tioned (see Chapter 18.1).
 make sure that there is sufficient ground
clearance under the footrest. Experience
shows that this should not be less than 4
cm (see Chapter 23).
17.3 Adjusting the tipping point
Optimum product tipping behaviour is
achieved when the axle mount of the drive
wheels is close to the body centre of gravity. A
product adjusted like this can be driven with
little effort and it also makes it possible to
manage a slightly uneven surface or edges by
tipping slightly.
Driving on both drive wheels (doing a wheelie)
is relatively easy to learn. Inexperienced
wheelchair users must be prevented from tip-
ping over backwards by means of anti-tipping
supports. In any case, the setting should be
made to suit the wheelchair user's individual
requirements and abilities to ensure safe oper-
ation.
Setting the tipping point is carried out by
changing the positioning of the drive wheel
bushings in the wheel plates.
Figure 15: Wheel plate and drive wheel bushing
(view from outer side of product, drive wheel re-
moved)
To adjust the tipping position, first remove the
drive wheels via the quick release axles (see
Chapter 21.1), so that you have direct access
to the wheel plates. Then proceed as follows:
1. Loosen the inner steel fastening nuts (AF
30 mm) on both sides.

2. Now slide the drive wheel bushings along
the slots in the wheel plates to the desired
tipping point position. Make sure that the
two drive wheel bushings on the right and
left are in exactly the same tipping point
position. The scale on the front of the
wheel plates can be used as a guide.

3. Then tighten the inner steel mounting nuts
(AF 30 mm) on the right and left to 70 Nm.
17.3.1 General instructions
After each change to the tipping point:
 the caster wheel axles must be readjusted
(see Chapter 22.4).
 the brakes must be readjusted (see Chap-
ter 25).
Extreme settings such as drive wheels
mounted far to the front are only permitted for
experienced wheelchair users who are able to
actively shift their weight forwards during oper-
ation.
To minimise the risk of tipping backwards,
we recommend using anti-tipping supports,
even with anti-tipping settings.
18 Back system
Avoid falling into the seat/seating plate
and backrest upholstery/back shell as it signifi-
cantly increases the risk of a misalignment,
falling over, or defects.
18.1 Backrest angle
18.1.1 Adjustment options with backrests
firmly bolted to side sections
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
With backrests bolted firmly to the side sec-
tions, there are no options for flexible backrest
angle adjustment without tools. However, per-
manent adjustment of the backrest 5° forwards
or backwards is possible using tools. To do
this, there are three holes in the rear area of
the side section at the top and an elongated
hole at the bottom to position the backrest
tubes. To adjust the backrest 5° forwards or
backwards, loosen both M5 fixing screws
(AF 3 mm) with washers on each side and
position the fixing screws with washers in the
desired holes of the side section at the top and

bottom in the corresponding position in the
elongated hole (same position on the right and
left). Then tighten up the M5 fixing screws
(AF 3 mm) again to 6 Nm and secure them
with thread lock fluid.
Figure 20: Adjusting the backrest position using
holes in the side section
18.1.2 Adjustment possibilities with an
adjustable backrest
If equipped with an adjustable and foldable
backrest, the backrest angle can be flexibly
adjusted without using tools and the backrest
can be completely folded away. The angle of
the backrest can be fixed in 7 positions in 5°
steps.
Observe that the centre of gravity is shift-
ed further to the rear by the enlargement of the
angle between the backrest and the seat sys-
tem and thus, the tipping point of the product is
reached much sooner.
18.1.3 Instructions for sitting posture with
an adjustable backrest
For a good sitting posture, we recommend
positioning the backrest vertical to the ground,
where possible.
With low backrests with adaptable belt cover
due to a disability, it may be advantageous to
slightly tilt the backrest forwards and to slacken
the top belt of the backrest upholstery so that
the slack in the upper area is greater in order
to achieve good sitting stability under certain
circumstances (see Chapter 18.2).
The adjustment possibility of the backrest an-
gle supports active sitting and ensures for flex-
ibility of the wheelchair user. An example in the
following:
 if the angle of the seat has been changed
(see Chapter 17.2), the angle of the
backrest can be respectively readjusted.
 When driving on slopes and when trans-
porting baggage (e.g. backpacks) on the
backrest, the centre of gravity shifts more
to the rear and the risk of tipping increas-
es. Then this can be counteracted by a re-
spective angle adjustment of the backrest
to the front.
 For comfortable seating, the backrest can
be locked in a position to the rear so that
the backrest is tilted slightly back.
18.1.4 Adjusting the backrest angle or
folding down the backrest with an
adjustable backrest
To adjust the backrest angle, relieve it (oth-
erwise there is a risk of tipping) and then loos-
en the locking pins that engage in the locking
holes of the side sections on the left and right.
For this purpose, grasp under the seat cover
and in the middle, pull the cord to the front that
is linked to the locking pin.
