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

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

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.
