JOKER EVOLUTION 5
1.4 Use
The JOKER EVOLUTION wheelchair is self propelled
which means that it can be moved manually by using the
hand rims on the rear wheels. It can be used in rehab as
well as in more active situations and is ideal for a wide
range of users with different kinds of pathologies.
It is used to guarantee either fully independent or
assisted (with an attendant) movement for a person with
reduced or fully impaired movement in one or more parts
of the body. As it has such a large range of accessories
and configurations the wheelchair can be used in full
safety both inside and outside.
Where the user is affected by particularly severe
pathologies or with people who are unable to move at all
on their own, an attendant is always advisable. We also
discourage use over hilly, particularly soft, sandy or
uneven ground, slopes exceeding the recommended
gradient and acid environments.
Its compact size and structure make the JOKER
EVOLUTION wheelchair ideal for use by both
teenagers and adults.
1.5 General advises
Before using the wheelchair we recommend that you
carefully read Chapter 2.0 “Safety” and Chapter 5.0
“Using the wheelchair,” which are essential for safe use
of the wheelchair
2.0 Safety
The Progeo® JOKER EVOLUTION wheelchair is a
medical device and therefore it should not be lent to
other users even for short periods of time.
Making any unauthorised modifications or using un-
approved parts may change the wheelchair structure
and create unsafe condition as well as possible harm
to the chair and occupant is forbidden.
T H E M A N U FA C T U R E R W I L L A C C E P T
NO R E S P O N S I B I L I T Y I N C A S E S O F
N O N - COMPLIANCE WITH THE INSTRUCTIONS
OR RECOMMENDATIONS AS SET OUT IN THIS
MANUAL AND ANY SUCH ACTIVITY WILL RESULT IN
THE IMMEDIATE CANCELLATION OF THE
MANUFACTURER'S WARRANTY .
2.1 Movements:gettinginandoutofthewheelchair
While getting into or out of the wheelchair do not place
your feet on the footplate. This could result in the
wheelchair tipping up, possibly causing harm both to the
chair and to the occupant.
Getting in and out of the wheelchair must always be done with
extreme care and caution, even by experienced users, and must be
performed only after receiving instruction from specialised and fully
trained personnel.
If getting in and out of the wheelchair is difficult an attendant should
be present. All of these actions should in any case be performed
based on your particular pathology and therefore on your own level
of independence

JOKER EVOLUTION 6
The general rules to respect while getting in or out of the
wheelchair safely are:
Ensure the wheelchair is parked on a solid, flat or regular
surface. Do not get in or out of the wheelchair while on hills or
uneven ground which could render the wheelchair unstable
and cause the occupant to fall and/or the wheelchair to
overbalance.
The brakes should be engaged (see chapter 5.6 “Using the
brakes”)
Get your feet off the footplate (see chapter 2.9 “Footplate”)
when getting out, and bring them close to the footplate when
getting in.
Lean on the wheelchair and where possible on a stable object
nearby. Use the force of your arms to raise and move your
body (see fig. 1) In cases where the occupant is not able to
perform this movement alone, or if the movement is to be
performed on an uneven surface, an attendant should be
present (see fig. 2)
While getting in or out of the wheelchair never lean or
sit on the clothes protector. It could bend or break,
possibly resulting in injury.
If your wheelchair is equipped with swing away of the
chair is recommended to be swung backward (see
chapter 7.1 “Height adjustment removable swing away
armrests”)
Fig.1
Fig.2

JOKER EVOLUTION 7
2.2 Starting to use your wheelchair
Finding the centre of gravity - the point at which the
wheelchair will tip back
Your ability to control and safely tip the wheelchair depends mainly
on your seating position and the location of the centre of gravity in
respect to the rear wheels.
The JOKER EVOLUTION model allows you to adjust the
position of the rear wheels (see chapter 6.4 “Rear wheels
adjustment”).
Remember that every adjustment to the rear wheels
affects the wheelchair's stability and could therefore
increase the possibility of overbalancing The correct
positioning of the rear wheels depends on many factors,
among them: the occupant's weight, type of disability and
ability to manoeuvre the wheelchair. The manufacturer
will supply the wheelchair with the rear wheels positioned
according to instructions given on the original order form.
Finding the point at which the chair will safely tip
back requires the presence of an attendant who must
be standing behind the wheelchair ready to prevent it
from overbalancing.
In order to find the point at which the chair will easily tip back
and, consequently, the range within which it is safe to manoeuvre
the chair, proceed in the follows (see fig. 3):
You are sitting on your chair. hold the hand rims on the rear
wheels firmly.
Then, move the hand rims slightly backwards and while
moving your weight backwards, push the hand rims forward
with a jerk and the front of the chair will rise.
At this point, by moving your body gently backwards and
forwards while moving the rear wheel backwards and forwards
using the hand rims, it will be possible to find the centre of
gravity and the point at which the chair will safely be
controlled.
IN ORDER TO PREVENT THE WHEELCHAIR FROM
OVERBALANCING DURING NORMAL USE WE
RECOMMEND MOUNTING ANTI TIPPER WHEELS
WHICH ARE SUPPLIED AS AN ACCESSORY TO
THIS MODEL.
(see chapter 7.3“Anti-tip wheels”)
2.3 Dealing with obstacles: stairs and steps
While getting over obstacles such as stairs and steps,
approach the obstacle at a moderate speed
Fig.3

JOKER EVOLUTION 8
Never attempt to go over steps or other obstacles
that are over 20cm (6 inches) height.
If particularly difficult obstacles are encountered an
attendant should always be present at the back of
the wheelchair in order to ensure complete safety.
Going over obstacles alone
Before attempting to go down a step or over any kind of
general obstacle alone (without the presence of an
attendant), you will need to have control over your
wheelchair and know how to tip it while maintaining your
balance over the rear wheels (see chapter 2.2 “Starting
to use your wheelchair”).
Going down steps on your own (see fig. 4)
Bring the wheelchair right up to the leading edge of the
obstacle .
Raise the front wheels by tilting the wheelchair while
maintaining balance.
Move the rear wheels carefully down to the obstacle; during
this phase hold the handrails to control the descent .
Once the rear wheels have descended the obstacle, tilt the
wheelchair forward until the front wheels touch the ground
again.
Going up a step alone
(see fig. 5)
Bring the wheelchair right up to the leading edge of the
obstacle .
Raise the front wheels and tip the chair back while maintaining
balance
Using the handrails, carefully move the rear wheels forwards
until they touch the edge of the step.
Fig.5
Fig.4

JOKER EVOLUTION 9
Tip the wheelchair forward until the front wheels are on top of
the obstacle.
Lean forward in the chair so that the rear of the chair is lighter.
Hold the handrails tightly and move the rear wheels forwards
bringing them over the top of the obstacle.
Going down stairs with an attendant
(see fig. 6)
Take the wheelchair right up to the obstacle so that the front
wheels are as close as possible to it.
Grip the rear handles tightly and push down in order to raise
the front of the wheelchair.
Keep the wheelchair in this position and accompany it down
the stairs one step at a time. The occupant seated in the chair
can assist the attendant by using the hand rims.
At the end of the descent, tip the chair forward so that the
front wheels are once again touching the ground.
In order to help the attendant to tilt the chair we
advise the use of the tip-back assistance device
which is supplied as an accessory to this model (see
chapter 7.4 “Tipping aid”).
Going up steps with an attendant (see fig. 6)
Move backwards towards the step so that the rear wheels of
the wheelchair touch it .
Grip the rear handles of the wheelchair tightly and pull hard
while keeping the wheelchair tilted (with the front wheels
raised in order to prevent the occupant from slipping out of the
chair) until the rear wheels are over the step.
Keeping the wheelchair tilted, pull it away from the step
enough to allow the front wheels to touch the same level
ground.
Fig.6

JOKER EVOLUTION 10
2.4 Dealing with obstacles: slopes or inclines
Going uphill
(see fig. 7)
Moving up any kind of slope should be done with extreme care. The
occupant must move at speed by generating force on the rear
wheel while at the same time maintaining control over the
wheelchair.
We recommend that occupants who have not yet
completely mastered safe use of the chair should mount
the anti-tip system which is supplied as an accessory to
this model and which is useful for preventing the chair
from tipping over backwards (see chapter 7.3 “anti-tip
wheels”).
Lean forwards and keep your weight forward in the chair in
order to prevent the wheelchair from tipping over backwards.
Hold the rear hand rims tightly.
Move the wheelchair hard up the slope whilst ensuring that
you move smoothly and fluidly. Do not move your upper body
backwards and forwards in the chair.
The maximum gradient that can be attempted in
complete safety is 6% (3°).
Going downhill (see fig.8)
In order to go downhill safely, the occupant has to keep constant,
controlled speed and direction over the entire slope.
Fig.8
Fig.7

JOKER EVOLUTION 11
Approach the slope at a moderate speed
Keep your weight backwards in the chair to avoid slipping out.
Hold on to the hand rims on the rear wheels and allow them to
slide slowly through your hands.
The occupant should be able to stop the wheelchair at any
time simply by blocking the motion of the handrail.
2.5 Ensuring stability
You will encounter situations which will require you to lean out of
the wheelchair. These apparently simple movements could, if not
performed with care, result in a loss of stability and in possible
overbalancing of the chair.
In order to gain the maximum control over your wheelchair the
following list of common situations is reported. We ask you to pay
particular attention to these guidelines so as to maintain balance
and stability
Leaning forwards (see fig. 9)
Ensure that the front wheels of the chair are pointing forwards.
In order to do this, move the chair forwards and then
backwards.
Put on the brakes in order to prevent the chair from moving
suddenly during the movement.
Lean forward in such a way that your upper body does not
move beyond the front wheels at any time. Moving the weight
of the body excessively forward may cause the wheelchair to
tip up onto the front wheels and overbalance possibly causing
harm both to the chair and the occupant.
In order to ensure greater stability the occupant should hold
on to the wheelchair with his or her free hand.
Do not lean too far forward; you may fall out of the
chair
Do not move forward by sliding your pelvis across the
seat cushion in order to reach objects that are too far
away.Thechaircouldoverbalance.
Never hold on to the backrest in order to ensure the
stability or to help your movement The backrest could
close and cause severe damages to the end user.
Fig.9

JOKER EVOLUTION 12
Leaning backwards (see fig.10)
Ensure that the front wheels of the chair are pointing forward
move the wheelchair forwards and then backwards.
do not engage the brakes.
lean backwards without changing your sitting position.
Do not lean too far back over the backrest, the
wheelchair could overbalance
Leaning out sideward (seefig.11)
Do not move your upper body beyond the rear wheel as the
wheelchair could overbalance .
With your free hand, for greater safety and stability, hold on to
the wheelchair
2.6 Tyre pressure
In order to guarantee consistent, precise running and braking, it is
necessary to ensure that the tyres are correctly inflated.
Remove the plastic valve cover on the valve that is found on
the rim of the rear wheel (see fig.12)
Use a compressor to bring the pressure to the correct level
(see table 1).
Screw up the plastic valve cover
Fig.11
Fig.10

JOKER EVOLUTION 13
Fig. 12
Check the tyre pressures weekly using “table 1” as a
guide.
Incorrect inflation of the tyres (especially if too low)
causes incorrect functioning of the brakes and the
wheelchair may not stop (see chapter 6.8 “Brake
adjustment”).
A correct tyre pressure makes the wheelchair much
more fluent and easier to move and control
To inflate the tyres always use a compressor with a
gauge.
Do not use hand pumps or other systems.
Do not exceed the pressure indicated in the pressure
table as the inner tube or the tyre may get damaged.
Pay particular attention to type of tyre fitted, as
shown in “table 1”.
Table1Rear Wheel Tyre Pressure
TYRE PRESSURE
High Pressure 7 BAR
High pressure profile 7 BAR
Marathon Plus 10 BAR
Anti puncture Does not require inflation
The anti puncture tyres does not require inflation. This
type of tyre needs less maintenance and eliminates the
costs and inconvenience due to repair or replacement of
the inner tube.
However, during normal use, they are less fluent than
traditional tyres or tubulars
2.7 Quick release axles
After each procedure carried out on the rear wheels, ensure that
the quick release axles are well inserted (see fig.13)(seechapter
5.5“Quick release rear wheels).
A check up of the quick release axles is a periodic
procedure the user should carry out .

JOKER EVOLUTION 14
Check the correct functioning
of the quick release axle
without any person sitting on
the chair.
Disengage the brakes
With one hand on the
backrest tube, lift the chair a
few centimetres on the side
where the rear wheel will be
removed.
Take hold of the wheel hub
with your fingers laced
through one or two spokes
and pull and push hard (as
indicated by the arrow) in
order to ensure that the wheel
is properly fastened
If the axles are not correctly placed and fastened
they may work loose during normal use and
could result in the wheelchair overbalancing and
possibly causing injury.
2.8 Backrest locking system
After opening the backrest (see chapter 5.3 “Opening the backrest”)
always check carefully that the pin “A” is securely engaged in the
hole of the backrest plate “S”. When the backrest is fully opened,
an audible “click” will indicate it is securely locked (see figure14).
2.9 Footplate
There are two kind of footplates available for the model JOKER
EVOLUTION:
•with aluminium plate – angle adjustable (figure15)
•with carbon fibre plate (figure16)
On their upper part all these footplates are particularly designed to
offer greater rigidness and, at the same time, to reduce and control
the possible sliding off of the feet so as to keep them close to each
other.
To prevent the feet from sliding off backwards, we
recommend the use of the calf strap provided as
standard in this model (see chapter 2.10“Calf strap”).
Fig.13
Fig.14
A
Fig.15 Fig. 16

JOKER EVOLUTION 15
When moving in and out of the wheelchair it is
recommended not to keep your feet on the footplate;
an excessive weight on the footplate may result in it
breaking and could in turn cause harm to the user.
2.10 Calf strap
In some cases, depending on the diameter of the front wheels and
the width of the wheelchair, the front wheel, as it rotates for turns etc
maycomeintocontactwiththeoccupant'sheel.
In order to avoid any such contact (which could result in the chair
overbalancing), the chair is supplied with a calf restraining belt
which should be adjusted so that the occupant's feet do not
come into contact with the front wheels of the chair at
any time (see fig.17).
2.11 Tubular armrests
The model JOKER EVOLUTION can be provided with tubular
armrests (figure18).
The armrests are considered as accessory and must
therefore be ordered separately. They are particularly
useful for people with reduced mobility of their hands or
arms and for those with limited upper body movement
who require better stability when sitting on the
wheelchair.
The armrests must not be used to carry the
wheelchairoras a support.
Fig.17
Fig. 18

JOKER EVOLUTION 16
The tubular armrests are only locked when they are in
their standard position for use (facing forwards and
parallel with the sides of the wheelchair) (see fig. 17). In
all other positions they can turn and for this reason
always ensure that they are correctly positioned
before use (see chapter 7.1 “Height adjustable,
removable,swing awayarmrests”).
If this instruction is ignored the wheelchair or the
user may overbalance.
Do not use the armrest as hand hold to raise the
wheelchair; this may cause the armrests to come off
from their supports and in turn cause harm to the
user and to the wheelchair
Do not use the armrest as supports when making
transfer .We indeed recommend to swing the armrest
away on the side of the transfer so as to help the
operation.
2.12 Fasteners
After each maintenance cycle ensure that all nuts, bolts and screws
are correctly tightened as they may loosenduringnormaldailyuse.
We recommend checking that all hardware is
correctly tightened at least once a month.
If necessary consult an authorized PROGEO dealer or
technician.
2.13 Wheelchair lifetime
Under normal daily use the PROGEO
®
wheelchair has a lifetime of
5 years provided that it receives careful maintenance at the
correctintervals.
The lifetime will considerably increased if the wheelchair is used
only indoors or notonadailybasis.
2.14 Avoiding accidents
Movements
Avoid sudden, jerky movements during use of the wheelchair
asthiscouldcauseitto overbalance.
If obstacles are run into, avoid sudden movements (such as
abruptbraking).
The risk of skidding increase on irregular or damp ground.
Going over obstacles as steps and ramps has to be done
carefully (ask an assistant for help ).
For greater safety, when moving across inclined or potentially
dangerous terrains it is recommended the presence of an
attendant behind the wheelchair.
Speed
Always adjust your speed with relation to the type of terrain and
conditions. As a general rule, we advise a constant, regular speed
avoidingsuddenaccelerationsorchangesindirection.
Using the brakes
The parking brakes have been designed to hold the wheelchair
stablewhenitisstationary.

JOKER EVOLUTION 17
For safety reasons we do not recommend using the
parking brakes while the wheelchair is in motion(see
chapter 6.8 “Brake adjustment”)
When using the brakes a great care should be taken
to avoidinjurytothehandsorfingers.
3.0 Loading the wheelchair
There is no single best way to load the wheelchair in a vehicle.
The kind and level of the patient disability (his/her ability to control
his/her upper body, arm and hand movements),physical strength
(for an old person or a child the operation may result too hard) and
the kind of vehicle that will be used are all factors.
It is clear that all these factors are too many to give a single precise
procedure to fit all cases , therefore this information has to be taken
as general advices.
Perform all car loading activities with extreme care
and only after receiving instruction from specialised
servicepersonnel with our authorised dealers.
If these procedures seem to be unsafe or difficult we
recommend asking an attendant for help.
Never transport in a vehicle an occupant sitted on the
wheelchair as these wheelchairs are not designed for
thiskindof use.
If the occupant has to be transported while seated in
the chair you are reminded that the wheelchair in its
standard configuration is not supplied with seatbelts.
Any safety belts for vehicle transport must be
installedbyspecialised personnel.
Transport with an attendant
In cases where the physical limitations of the occupant prevent
him/her from moving and loading the wheelchair into the car on

5.0 Using the wheelchair
5.1 Use
The JOKER EVOLUTION is a ultra light rigid frame active
wheelchair.
This is the only wheelchair available which uses crush resistant
aluminium alloy tubing to increase the strength and rigidity of the
wheelchair. Because of its characteristics of reduced weight,
adaptability (configuration) and smoothness this wheelchair is ideal
for daily use by occupants with severe pathologies (with limited
movement in the legs, arms and upper body) as well as more
active occupants (able to perform activities without assistance). The
wheelchair has been designed for indoor (flats, gyms, schools,
libraries, etc.) as well as outdoor (roadways, pavements,
courtyards,etc...)use.
During the day-to-day use of the wheelchair the occupant
could encounter rough or irregular grounds (such as
gravel, holes, etc) or slippery terrain (wet, sandy, dusty or
oily ground etc).
In these cases and in all other cases where the use of
the wheelchair could be difficult or even dangerous
(both for the occupant and for the wheelchair itself), we
recommend using extreme care and attention
combined with smooth motion avoiding sudden
braking or acceleration (see chapter 2.0 “safety”).
In case of extreme difficulty or danger it is always
advisable to have the help of an assistant
In order to prevent overbalancing, the maximum
gradient recommended for this wheelchair is 3°(6%)
(see chapter 2.4 “Dealing with slopes or inclines”).
The maximum weight that the Joker model is safely
able to carry is 125kg.
