5 Introduction
Before starting your journey, familiarise
yourself with these operating instructions paying particular attention to the safety information
and hazard warnings contained within them.
Why not let therapists and doctors 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. Clarify with them as well which wheelchair techniques you can learn on the basis of your ability. Under no circumstances should you do
anything with or in the product which you have
not learnt to and have not mastered.
You, your carers and assistants should
also seek advice from your therapists and doctors as well as your specialist retailer on the
use and settings on your product as well as
available safety accessories (e.g. anti-tippers
and waist belt). It is then important that you
also follow this advice.
Overestimating your own ability or underestimating a dangerous situation or action with
the product can have serious consequences
for you and other people.
If you are not sure how to handle the
product or if technical faults occur, please contact your dealer or PRO ACTIV before using it.
Make sure that when combining your
product with equipment made by other manufacturers (e.g. seat cushion, drive devices,
etc.) that the serviceability of the individual
components and the unit made up of them is
ensured. You can get information on the suitability of a combination from the manufacturer
of the external components or from your specialist retailer.
6 Product description / purpose
Using the product as intended is essentially
based on replacing the walking ability of a
person who has difficulty walking or cannot
walk on a paved path by driving with the
wheelchair as far as is technically feasible. In a
figurative sense, "walking" means walking
speed when using a wheelchair. Particular
attention needs to be paid to this when using
an auxiliary drive.
7 Acceptable usage and operating
conditions / places of use
Only use the product on paved surfaces. Avoid
driving on unpaved or loose surfaces (e.g. on
loose gravel, in sand, mud, snow, ice or
through deep puddles of water), as this may
result in incalculable risks.
The maximum permitted load of the product in
its standard design is a 50kg payload. Individual customisation can be made to accommodate a higher load; this will be indicated on the
ratings plate. Please ensure that the load limit
indicated on the ratings plate is not exceeded,
even when transporting objects and carrying
out strength exercises in the wheelchair.

9 Commissioning
The product is handed over to you ready to
use by a PRO ACTIV dealer.
You will be fully instructed in the use of the
product based on the operating instructions
included in delivery. If you wish (recommended
by PRO ACTIV), you will be presented with a
record of training and a hand-over certificate
as written evidence and in addition the operating instructions and any other accessories for
your own use. The form for the record of training and the hand-over certificate can be found
in chapters 32 and 33.
It is recommended that you take along an assistant to the training so that, if required, they
can assist you later when handling the product.
During the initial commissioning of the product,
drive at minimum speed and become accustomed 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.
10 Hand-over
The hand-over must be done by your dealer or
a field representative from PRO ACTIV. During
the hand-over, the record of training (chapter
32) and the hand-over certificate including the
associated check list (chapter 33) must be
filled in. The dealer should send a copy of the
completed documents to PRO ACTIV for filing
either as a scanned file via e-mail, by fax or in
the post. These documents are available as
pdf files which can be completed in the
download area at www.proactiv-gmbh.com
.
11 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.
Before starting out, check that the product's brake works. If all existing brakes are not
fully functional, no trips may be taken.
Always ensure that your feet cannot slip
off the foot plate when using the product, if
necessary by using a special securing device.
Check tyre pressures at regular intervals.
Ensure that you comply with the manufacturer's specifications which can be found on
the tyres. Tyre pressure which is too low affects on the driving behaviour of the product
and has a negative effect on the braking efficiency.
Operating instructions LITTY 4you
6
Before using the product, ensure that the
anti-tippers are in good working order. In this
case, it must not be possible to swivel the antitippers to the side when in operating position
without having to unlock them first.
The lower edge of the anti-tipper wheels
may not be any more than 5 cm from the
ground. If a larger gap is required or necessary, then you need to work with your therapists and doctors to practice and learn to handle the increased risk of tipping.
Due to environmental effects, it is possible
that the properties and therefore secure attachment of the push handle covers may
change detrimentally. For this reason, it is
important to check 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
.
Every time before you use the product,
make sure that the anti-tippers 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 its optional extras, the
wheelchair may have folding /closing mechanisms which pose a risk of crushing injuries
(e.g. trapping your fingers). For this reason,
please allow your specialist retailer to explain
how to work these mechanisms and then have
a go yourself under instruction.
If required, you can have a suitable waist
belt fitted to your product. Please make sure
that the waist 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.
12 Safety instructions - while driv-
ing / using
Please note that some parts of your product can become extremely hot in at hot ambient temperatures (e.g. a 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 provide any warranty for personal injury and material damage caused by such stresses. There
are also certain risks that exist at extremely
low temperatures, which can be minimised by
wearing appropriately insulating clothes for
example.
Before driving up or down slopes or hills
with the product, you should be proficient in the
safe handling of the product on the flat.
Use particular caution when approaching
stairs, edges, drops or other hazard areas.
When driving round a bend, reduce your
speed to a minimum.
Please note that the knee lever wheel lock
which your product is fitted with is a parking
brake which may only be applied when the
product is at a standstill. This is not a service
brake which is suitable for reducing speed.
Do not attach objects (carrier bags, etc.)
to the product.
When driving on areas which are used for
pedestrians, observe the maximum permitted
speed (walking speed 6 km/h) and keep a
sufficient distance (if possible the width of a
wheelchair) from the kerbs or other obstacles
and other road users.
Avoid driving on unpaved or loose surfaces (e.g. on loose gravel, in sand, mud,
snow, ice or through deep puddles of water).
Operating instructions LITTY 4you
7
If you encounter new driving situations
which are unknown to you, approach them with
great care. If you consider that the risk is too
high, you must immediately abort the driving
manoeuvre and, if required, call for help to
assist you in extracting yourself from this situation.
The product can affect other devices, for
example theft protection barriers in department
stores.
The product is only designed to be used
to transport persons with limited mobility and
must not be used for any other purpose, e.g. to
transport goods.
You may only drive on slopes where the
product can be safely controlled with the hand
rims.
When travelling on poorly maintained
paths with potholes and loose stones, drive
carefully to try to prevent the caster wheels
from becoming locked.
When reversing, the anti-tippers should
always be used as there is an increased risk of
tipping over. If this is not possible, then ask
other people to help ensure that there is no risk
of tipping over.
Due to the high risk of tipping up and being injured, you should never try to ride an
escalator in the wheelchair.
The product may only be propelled using
the hand rims. If you drive propelling 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 vicinity 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 protect the spokes with a spoke
shield for example to minimise the risks.
Make sure that the passive illumination
(reflectors) are always on your product, are in
perfect condition and are clearly visible.
13 Safety instructions regarding
obstacles
Obstacles like curbs, for example, should
always be negotiated driving forwards and
always using the minimum speed required.
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. This could result in falls, serious injuries to the user or thirdparties as well as damage to the product.
Always drive over curbs or other obstacles
so that you cross them to the front or at right
angles. If you approach them at an angle, or
only have one rear wheel on the obstacle,
there is an increased risk of tipping over to the
side which can result in serious injuries to the
user and third-parties as well as damage to the
product.
If the wheelchair user needs to be transported over an obstacle, such as a step, and if
there are suitable facilities such as a ramp or a
lift available, then these should be used. If
such facilities are not available, then the obstacle is to be overcome by being carried by
two helpers. When carrying the wheelchair, it
may not be lifted by the side sections, the drive
wheels or the footrests. We recommend holding the product by the lower frame tubes of the
main frame and holding the back cross bar.
Before overcoming an obstacle (steps,
threshold, etc.) the anti-tippers need to be
swivelled from operating to passive position or
need to be detached so that they do not make
contact with the step you are trying to get over.
Otherwise this could lead to a serious fall. After
overcoming the obstacle, the anti-tippers need
to be put back in operating position (Chapter
19).
Operating instructions LITTY 4you
8
To overcome obstacles such as curbs or
steps, the wheelchair needs to be actively
tipped as otherwise the caster wheel could jam
at right angles to the obstacle and could block.
This could damage the caster wheel or the
caster fork and cause injury. If actively tipping
it is not possible, then the obstacle 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.
14 Safety instructions regarding
dangerous locations and dangerous situations
The operator of the product determines the
route to be driven taking the operating instructions, their driving knowledge and physical
abilities into consideration.
The personal driving skills are particularly important in the following dangerous locations
which are provided as examples; the product's
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 which are covered in leaves, snow
or ice.
ramps and lifting equipment on vehicles.
When driving in a circle or turning on hills
or downward slopes, there may be an increased tendency to tip over to the side due to
the changes in the centre of gravity. Always
perform these driving manoeuvres with increased caution and only at slow speed. If
required, the driving manoeuvre must not be
performed or only with the help of an assistant.
When crossing main roads, intersections
and level crossings, extreme caution is
needed. Crossing rails in the road or at level
crossings must never be undertaken when
travelling parallel to them, as otherwise the
wheels could become caught which would
result in the product being unable to manoeuvre.
When driving on ramps and lifting equipment on vehicles, extreme caution is needed.
When lifting or lowering the ramp or the lifting
equipment, the parking brake should be applied.
The grip of the tyres on the ground is reduced in the wet. There is an increased risk of
slipping. Adjust your driving, braking and steering behaviour accordingly.
15 Safety instructions - after driv-
ing / use
Apply the parking brake on your wheelchair before getting out.
When getting out of the wheelchair, do not
tread on the footrest due to the risk of tipping
up.
16 Individual setting options
16.1 Seat height front and back & an-
gle of seat
The angle of the seat plate can be adjusted
using the four rotation points on the sides.
To do this, two M6 fixing screws (AF 4 mm)
need to be undone on each side. Using an
Allen key (AF 6 mm) the four rotation points
can now be rotated to the required position to
adjust the required seat heights.
After adjusting the seat height at the front and
back, make sure that the opposite rotation
points are positioned symmetrically flush or
respectively, that the opposite rotation points
are in the same position. Afterwards, tighten
the M6 fixing screws on the rotation points (AF
4 mm) again using 7 Nm torque.
Operating instructions LITTY 4you
9
Figure 1: Adjusting the seat heights using the rotating points
If you need a greater adjustment range for the
seat heights, the seat plate can be turned
over (seat height adjustment approx. 3 cm). To
do this, undo the M6 fixing screws at the rotation points (AF 4 mm) completely, remove the
seat plate and replace it turned upside down.
Please make sure that the straight edge remains at the front. You can see the seat plate
in the high and low position in the following
figures. Afterwards, tighten the M6 fixing
screws on the rotation points (AF 4 mm) again
using 7 Nm torque.
Figure 2: Seat plate in high position, slots down
Figure 3: Seat plate in low position, slots up
Every time the seat heights and angles
are adjusted, the position of the footrest needs
adjusting as well. Make sure the clearance
under the footrest is sufficient. Experience
shows that this should not be less than 4 cm.
You will find more details in Chapter 16.5.
16.2 Back shell position
The angle of the back shell and its spacing
position from the seat plate can be adjusted by
undoing the four M5 fixing screws (AF 3 mm)
in the mounting slots. The associated nuts
(AF 5mm) must be tightened for this. For good
seating posture, we recommend positioning
the back shell vertically if possible.
Figure 4: Mounting slots on the back shell
You can get an even greater adjustment range
by completely undoing the M5 fixing screws
(AF 3 mm) and moving them in the three des-
ignated boreholes in the clothing guard. Make
sure that the position of the M5 fixing screws
on the right-hand and left-hand clothing guard
are identical.

Once the position of the back shell has been
set, tighten the M5 fixing screws (AF 3 mm)
using 4 Nm torque again. The associated nuts
(AF 5mm) must be tightened for this.
Please note that if you move the back shell
further back, this will move the centre of gravity
further back which makes it easier to tip the
product up (Chapter 16.6).
16.3 Adjusting seat width
To widen the product, widening sets can be
ordered which are may up of an axle tube, seat
plate, back shell and back cross bar as well as
footrest support tubes or foot plate in a corresponding size.
Figure 6: Back cross bar and axle bar, view of product from rear
Contact your specialist retailer if you want to
change the width of the seat.
16.4 Adjusting the seat depth
To adjust the seat depth to suit body dimensions, the distance between the seat plate and
back shell can be infinitely adjusted. The adjustment is made by undoing the two M6 fixing
screws (AF 4 mm) on each side in the rotation
points.
Figure 7: Fixing screws on the seat plate in the
rotation points
Afterwards, the seat plate is shifted along the
slots on the fixing screws.
Figure 8: Possible directions of movement of the
seat plate with slots
Afterwards, tighten the M6 fixing screws (AF 4
mm) on the rotation points again using 7 Nm
torque.
After adjusting the seat plate, it may be necessary to adjust the position of the back shell.
Please pay attention to the advice in Chapter
16.2.
16.5 Adjusting the lower leg length
adjusting the footrest
The footrest support tubes are clamped on the
left and right onto the lower frame tubes into
the foot bracket clamps. The foot bracket
clamps are secured against twisting through
interlocking serration.

Figure 9: Illustration of terms
Figure 10: Serration on the foot bracket clamp, with
positive locking
To adjust the length of the support tubes,
the M6 fixing screws (AF 5mm) on the foot
bracket clamps have to be undone. The length
of the support tubes can then be adjusted.
Figure 11: Fixing screws on the foot bracket clamps
If the angle of the support tubes is to be
changed, then the M6 fixing screws (AF 5 mm)
need to be loosened further so that the positive
locking on the interlocking serration is released. Now the angle of the support tubes can
be adjusted.
Once you have finished adjusting the angle
and the length, tighten the M6 fixing screws
(AF 5 mm) again using 7 Nm tightening torque.
Figure 12: Serration on foot bracket clamps, positive
locking undone
The angle of the foot plate can also be adjusted by loosening the M6 clamp screws (AF
5 mm) on the bottom of the foot rest. Once the
adjustment of the angle has been completed,
tighten the M6 clamp screws (AF 5 mm) with 7
Nm tightening torque. This tightening torque
should not be exceeded as higher tightening
torques can damage the clamp.

As an option it is also possible to choose a
foot plate which can be folded up towards the
back. If this angle is to be adjusted, then the
procedure is the same as above, however after
competing the adjustment work, the M6 clamp
screws (AF 5 mm) need to be secured with
thread lock fluid.
Measures need to be taken to ensure
there is sufficient ground clearance under the
foot rest. Experience shows that this should
not be less than 4 cm.
16.6 Adjusting the tipping point
The tipping point can be adjusted by adjusting
the seat plate and back shell. You will find
descriptions on this in Chapters 16.1 and 16.2.
An optimal tipping behaviour of the product is attained if the hollow axle of the drive
wheels is close to the body's centre of gravity
(as a general rule, slightly in front of the hips).
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 the two rear wheels
(doing a wheelie) is relatively easy to learn.
Inexperienced wheelchair users are prevented
from tipping over backwards by anti-tippers.
Although shifting the seat system forwards
will counteract the tipping danger, it also
makes it more difficult to turn, steer and tilt the
product. In any case, the setting should be
made to suit your individual requirements and
ability to ensure you can drive your chair
safely.
17 Drive wheels
17.1 Removing and attaching the drive
wheels
Figure 14: Locking knob in the middle of the wheel
axle
To remove the drive wheels grip through the
spokes around the wheel hub with your fingers.
By pressing the locking knob in the middle of
the wheel axle with your thumb, the wheels
can then easily be removed.
When attaching the drive wheels the locking
knob also has to be pressed. Special attention
should be paid here to ensure that the knob
springs out again after attaching the wheel as
otherwise it is not secured. You will know that if
you can see the index groove.

17.2 Checking and adjusting the wheel
tracking of the drive wheel
Well adjusted wheel tracking significantly improves the easy running characteristics of the
product. To check the tracking, proceed as
follows:
Position the wheel chair on a flat surface and
apply the parking brake on both sides.
Measure the axle heights (from the ground to
the drive wheel axle) and write this dimension
onto both tyres at front and back.
Figure 16: Drawing the axle height on the front and
back of both tyres
Afterwards measure the distance between the
drive wheels front and back at the height of
the axles along the markers. Ideally, the distance between the two drive wheels should be
the same size at the front and back. In general
it can be said that the distance between the
drive wheels at the front may not be larger than
at the back. Apart from that, the distance at the
back may not be more than 5 mm larger that at
the front. If this is not the case, the wheel
tracking needs to be corrected.
Figure 17: Distance between the markers on the
tyres (at axle height), back
To adjust the track proceed as follows:
1. Loosen the aluminium locking nuts on bo th
sides (AF 41 mm).
Figure 18: Drive wheel bushing and aluminium,
locking nut, product view from below
2. Set the tracking correctly again by turning
the drive wheel bushing (AF 22 mm). Here
it can be said that: If you turn the drive
wheel bushing in the direction of travel, the
track at the front will become more narrow.
If you turn it against the direction of travel,
it moves in the opposite direction.
3. Make sure that the distance at the front to
the frame on the right and left is the same.
Figure 19: Distance at the front to the frame
4. Measure the distance between the drive
wheels at the front and back again at the

open-ended spanner (AF 22 mm) to hold
the drive wheel bushing in position and
tighten the aluminium locking nut (AF 41
mm) with a tightening torque of 70 Nm.
17.3 Air pressure
Check the tyre pressure at regular intervals
and after being subjected to extreme temperatures. The maximum and if applicable, minimum tyre pressure is printed on the side of the
tyre.
If the tyre pressure is too low, then optimal
functionality of the knee lever brake is not ensured. Apart from that, there is an increased
risk of a flat tyre.
The tyre pressure increase with the temperature. If the pressure is too high, the tyre
may burst. For this reason, wheelchair tyres
may not be exposed to unusually high temperatures such as in a sauna or under glass in
the summer.
17.4 Other
If tyres, inner tubes or hand rims need to be
replaced, please contact your specialist retailer.
18 Caster wheels
18.1 Replacing the caster wheels
To remove a caster wheel, unscrew the M6
axle fixing screw (AF 4 mm) out on one side.
Figure 21: Axle fixing screw on caster wheel axle
Figure 22: Caster wheel with aluminium axle
Now you can see the aluminium axle with a
hexagon socket (AF 4 mm). This hexagon
socket is used to fix the axle in place, while the
second axle fitting screw (AF 4 mm) (Fig. 21) is
unscrewed. To do this, insert the Allen key (AF
4 mm) into the hexagon socket on the aluminium axle and hold it still. At the same time,
unscrew the remaining M6 axle fixing screw
(AF 4 mm) on the other side.
When attaching the caster wheel, proceed as
described above in reverse order. The tightening torque for the axle fitting screw (AF 4 mm)
is 7 Nm. The axle fitting screws need to be
secured with thread lock fluid.

18.2 Caster wheels flapping
Uncontrolled swivelling backwards and forwards of the caster wheels around their axes
on the caster fork (while moving) is called "fluttering".
If the caster wheels start fluttering, then
immediately reduce the speed you are travelling at to avoid the caster wheels jamming
sideways so as to avoid the risk of falling over.
The speed limit at which a caster wheel can
start fluttering, reduces with:
increasing size of the caster wheels
increasing weight of caster wheels
falling load on the caster wheels
decreasing caster length of caster wheels
The following options are available to counteract caster fluttering:
Fluttering can be reduced by reducing the
caster wheel diameter. This means install-
ing a small caster wheel in a different
wheel position in the caster wheel fork
(seat height thus remains the same) would
be one way of reducing fluttering. How-
ever, please note that using a smaller
caster wheel makes it more difficult to
overcome obstacles and makes tilting nec-
essary more often. The smaller the caster
wheel is, the more driving skill is required.
Another way to reduce fluttering would for
example be to use a light caster wheel with
the same diameter or, as described above,
with a smaller diameter.
It would also be possible to increase the
caster length. The caster length is the dis-
tance between the rotary axle of the caster
wheel fork projected onto the floor and the
wheel contact point. The wheel contact
point of the caster wheel trails behind the
rotary axle as it were. The caster length
has a stabilizing effect on moving in a
straight line. Increasing the caster length
can be attained by mounting the caster
wheel in a different wheel position on the
caster wheel fork (the caster wheel fork ro-
tary axle is then no longer completely at
right angles to the ground).
Figure 23: Caster length
18.3 Replacing the caster wheel forks
A distinction needs to be made between the
caster wheel forks with a bolt-on axle and
those with a quick-release axle.
18.3.1 Caster wheel fork with bolt-on axle
The caster wheel fork with a bolt-on axle is
removed using a wrench which is included in
the scope of delivery. This wrench is inserted
into the two holes on the protective cap on the
caster wheel bearing block and turned anticlockwise. The caster wheel fork needs to be
held still. Once the cap has been completely
removed, the caster wheel fork can be pulled
out.

When attaching the caster wheel fork with a
bolt-on axle, insert the caster wheel fork ro-
tary axle back into the caster wheel bearing
block and tighten the protective cap of the
caster wheel bearing block again using the
wrench and secure it with thread lock fluid.
18.3.2 Caster wheel fork with quick-release
axle
The caster wheel fork with a quick release
axle is removed by pressing the locking knob
between the caster wheel and the inside of the
caster wheel fork. Reach into the caster wheel
fork and press the locking knob. The caster
wheel fork can now be pulled out.
Figure 26: Caster wheel fork with quick release axle
and locking knob
When attaching the caster wheel fork with
the quick release axle, press the locking knob
again and insert the caster wheel fork rotary
axle back into the caster wheel bearing block.
When doing this, special attention should be
paid to ensure that the locking knob springs
out again after attaching the wheel as otherwise the wheels are not secure.
19 Anti-tippers
To reduce the risk of tipping backwards unintentionally to a minimum, anti-tippers are available as accessories. The anti-tippers are inserted into anti-tipper sleeves in the bottom
frame tubes which secures them against twisting.

Figure 28: Cylindrical pin in groove
A spring system on the anti-tippers can be
used for example to overcome obstacles to
swivel them from the operating to passive
position so that they can't get caught on the
obstacle. To swivel the anti-tippers away, pull
them each backwards out of the anti-tipper
barrels until the cylindrical pin protrudes from
the grooves and then turn these by 180° upwards so that the anti-tipping wheel points
upwards (Fig. 30). After releasing the antitippers, the cylindrical pin slots into the groove
again.
After passing the obstacle, use the same process to return the anti-tippers from the passive
to the operating position again. Make sure
that these have clicked back into place again
properly (Fig. 31).
When changing between passive and
operating position, always turn the anti-tippers
outwards in the direction of the respective drive
wheel as otherwise this could damage the
springs.
Figure 29: Operating and passive position of the
anti-tippers
Figure 30: Move anti-tippers from operating to passive position
Figure 31: Moving anti-tippers from passive to operating position
The anti-tippers have exclusively been
designed to minimize the risk of tipping over
backwards. They are not suitable for reducing
the risk of tipping forwards or to the side. There
are no safety accessories available to minimise
these risks. For this reason, handling these
risks need to be learnt in cooperation with your
therapists and doctors.

Before using the wheelchair, after every
load on the anti-tippers and after every adjustment to the product, make sure that the antitippers are fully functional. In this case the antitipper in operating position must not allow itself
to be pushed away to the side without undoing
it from its locked position (cylindrical pin in
groove). In addition to that, the lower edge of
the anti-tippers may be no more than 5 cm
away from the ground. If a larger gap is required or necessary, then you need to work
with your therapists and doctors to practice
and learn to handle the increased risk of tipping.
If the functionality of the anti-tippers
should no longer be given or if you are in any
doubt about the serviceability, then have it
checked by your specialist retailer and have it
repaired before any further use. Otherwise
there is an increased risk or falling of getting
injured.
For example, the anti-tippers can be com-
pletely removed using a quick pin to transport
the product. To do this, press on the locking
knob on the quick pin and pull it out. Afterwards, the anti-tippers can be pulled out of the
anti-tipper barrels.
Figure 32: Quick Pin with locking knob
The Quick Pins can then be inserted in the
boreholes in the frame tubes to prevent losing
them.
Figure 33: Anti-tippers removed and quick pins in
boreholes in anti-tipper barrels
To attach the anti-tippers again, plug the
anti-tippers into the anti-tipper barrels. Make
sure that you place the cylindrical pins in the
grooves. Then take a quick pin for every antitipper in your hand, press the locking knob on
the quick pin and insert it back into the borehole on the frame tube.
20 Brake

It can become necessary to adjust the brake
for various reasons:
You have changed the tyre or the tyre
pressure.
You have changed the wheel tracking of
the drive wheels.
The brake is pulling unevenly or insuffi-
ciently after extended use.
To adjust the knee lever brake, proceed as
follows:
1. Loosen the M5 fixing screws (AF 4 mm)
which are used to attach the brake to the
brake mounting bar on the brake mount.
Figure 35: Bottom brake mount
Figure 36: Brake mount and brake mounting bar
2. Position the open brake so that there is 2
mm clearance between the brake bolt and
tyre up to a maximum of 4 mm. You can
use the adjustment range provided by the
slots on the brake mounting bar.
Figure 37: Distance between brake bolt and tyre
from 2 mm to maximum 4 mm, with opened brake
3. Tighten the M5 fixing screws (AF 4 mm)
again using a tightening torque of 4 Nm.
4. Check that the brakes are adjusted correctly: On a slope (7° gradient), the wheelchair should stand firm with the brake applied. This will happen if with the brake applied, the tyre is depressed or deformed by
approx. 4 mm. When the brake is not applied, the brake bolt may not drag along
the tyre.
5. Retrospective fine adjustments can be
made at any time using the infinitely adjustable adjustment screw on the lower
mount of the wire rope. To do this, open
the lock nuts (AF 8 mm) and unscrew the
adjustment screw. This will tension the
wire rope until the required distance between the brake bolt and the drive wheel is
reached. Then tighten the lock nuts again
with a tightening torque of 4 Nm.

Please note that the knee lever wheel lock
which your product is fitted with is a parking
brake which may only be applied when the
product is at a standstill. This is not a service
brake which is suitable for reducing speed.
21 Push handles
21.1 Central single-hand push handle
The height of the central single hand push
handle can be adjusted without requiring any
tools. For the adjustment, the quick release
lever is opened and after successful adjustment, is closed again. The height can be infinitely adjusted.
Figure 39: Closed quick release lever
Figure 40: Open quick release lever, push handle
removed
To remove the push handle, the M4 end stop
screw (AF 3 mm) needs to be unscrewed and
the quick release lever needs to be opened.
Figure 41: End stop screw attached to bottom of
central single hand push handle
After every adjustment or after reattachment following removal, check that the push
handle is firmly attached in its position. If necessary the tension can be adjusted by turning
the quick release lever clockwise until it
reaches the end stop. In addition to that, the
M4 end stop screw (AF 3 mm) needs to have
been mounted again.
The central single hand push handle is also
available with a folding handle end (op-
tional). In this case, the angle of the handle
end can be adjusted in 10 steps using the push
button or can be completely folded down.

The central single hand push handle with
a foldable handle section may only be used
once the handle end has locked into position in
one of the steps. You can tell it has locked into
position as the push button springs out and is
visible.
21.2 Push handles offset to the back
Adjusting the height of push handles offset to
the back is possible without tools using the
quick release. To adjust the height, the quick
release levers are opened and after completing
the adjustment, are closed again. The height
can be infinitely adjusted. We recommend
adjusting both push handles to the same
height.
Figure 44: Closed quick release
To remove the push handles, the M4 end stop
screws (AF 3 mm) need to be unscrewed and
the quick releases need to be opened.
Figure 45: End stop screws mounted at the bottom
of the push handles offset to the back
After every adjustment or after reattachment following removal, check that the push
handles are firmly attached in position. If necessary the tension can be adjusted by turning
the quick release lever clockwise until it
reaches the end stop. In addition to that, the
M4 end stop screws (AF 3 mm) need to have
been mounted again.
22 Storage
When being stored, the wheelchair should be
kept in a dry environment and covered up
where possible.
To avoid corrosion and therefore malfunctions
or breakages of components, the product may
not be exposed to any aggressive environmental influences (salt in particular).
23 Transport
Personnel transport of the wheelchair user
or other persons in the product in a motor vehicle has not been tested by PRO ACTIV and
is therefore not approved. All vehicle occupants must only sit on the seats installed in the
vehicle during the journey with the associated
restraint systems. Failing to observe this leads
to increased risk of injury for the user as well
as for third-parties.
The wheelchair can be fitted with a headrest. These headrest systems are not suitable
for use as headrests when being transported in
a motor vehicle.
M4 End stop screws
Operating instructions LITTY 4you
22
The waist belt which may be fitted is not
designed as a safety belt in a motor vehicle
and may not be used for this purpose.
To reduce the weight, individual components, such as the caster wheel forks with
caster wheels and the drive wheels can be
removed for loading and stored separately.
Furthermore, if the product has been fitted with
push handles and anti-tippers, these can also
be removed. The product and all associated
components must be secured during transport
so that they are not damaged (e.g. by falling
over) and do not become a hazard to persons
or other products.
If the wheelchair user needs to be transported over an obstacle, such as a step, and if
there are suitable facilities such as a ramp or a
lift available, then these should be used. If
such facilities are not available, then the obstacle is to be overcome by being carried by
two helpers. When carrying the wheelchair, it
may not be lifted by the side sections, the drive
wheels, the pushing handles or the footrests.
We recommend holding the product by the
lower frame tubes of the main frame and holding the back cross bar.
24 Malfunctions
In the event of any malfunctions which cannot
be solved by yourself based on the operating
instructions included in the scope of delivery,
please contact your specialist retailer or PRO
ACTIV directly.
Malfunctions must be solved before any
further use or, if they occur during the journey,
this must be interrupted immediately.
25 Cleaning and care
Clean and grease the quick-release axles
on the drive and caster wheels as well as all
the ball bearings at regular intervals to ensure
everything works reliably.
Regular cleaning of the product is prescribed
to prevent the components becoming clogged
up due to dirt. In particular, the product should
be carefully cleaned after every major use, e.g.
summer or winter holidays.
Clean your wheelchair with water, solvent
or neutral cleaning agents. Do not use any
abrasive cleaning agents or aggressive, acidic
cleaners, to prevent scratching or fading of the
coating or the anodised parts.
The product must not be cleaned using
steam or high pressure.
To avoid corrosion and therefore malfunctions
or breakages of components, the product may
not be exposed to any aggressive environmental influences. If this cannot be avoided,
the wheelchair should be cleaned immediately
after such use and moving parts need to be
greased. Regular cleaning prevents corrosion
and increased wear.
If you need care products for your product,
please contact PRO ACTIV.
