- Weight Limit
The maximum recommended weight of the user is 120
kg. However, the level of activity is an essential factor. For
example, an active user who weighs 75 kg may subject the
wheelchair to more stress than that of a user who weighs
100 kg. To this purpose, we recommend that you consult
your retailer when choosing the model of wheelchair based
upon your daily life style.
1.1 Reaching an object from the chair
The limitations on reaching out from a wheelchair indicated
in the following diagrams have been calculated based on a
representative sample of wheelchair users:
- Only the arms should be extended beyond the seat of the
wheelchair. (gure 2).
- The body and head should remain within the boundaries of
the seat. (gure 3).

A GENERAL GUIDELINES
1. Safety and operating limits
For a safe operation of your wheelchair, the following para-
meters should be observed :
- Stability and balance
Your wheelchair has been designed to provide the stability
you need during normal daily activities.
Any movement in the wheelchair will have an impact on
the position of the centre of gravity, which may lead to the
wheelchair tipping and a fall.
To improve your safety when you move a lot or you trans-
fer your weight from one place to another, we recommend
using seat belts.
- Weight distribution (gure 1)
Many actions cause the user of a wheelchair to reach out,
lean over or move about within the wheelchair and outside
it. These movements cause a change to normal balance,
centre of gravity (G) and weight distribution of the wheel-
chair.

1.1.1 Leaning forward
Do not extend your chest over the armrest (gure 4).
In order to reach an object in front of you, you must lean and
bend down ; therefore, you must use the castors as a tool
(pointing them forward) to maintain stability and balance. An
accurate alignment of the wheels is essential for your safety
(gure 5).
1.1.2 Leaning backward
Position wheelchair as close as possible to the desired object
so that you can simply pick it up by stretching your arm
while sitting in the chair in a normal position. In any case, do
not lean backwards because you may cause the chair to tip
(gures 6 and 7).

1.2 Sideways transferring to other seats
This may be done without assistance provided that you are
sufciently mobile and have a strong enough torso.
- Move the wheelchair as close as possible to the seat
to which you would like to sit, with the castors pointed
forward. Lock the wheels by applying the brakes. Move the
weight of your body towards the seat (gure 8)
- While moving from the wheelchair to the seat, your body
will have little or no support. Where possible use a transfer
board during transfers.
- If you are more or less able to stand up and if your upper
body is sufciently strong and mobile, you can transfer
forward to another seat. Fold the footplate up and push
the footrest/legrest to the side, bend your body forward
leaning on the two armrests and lift yourself up; then shift
your body towards the place where you want to sit while
distributing your weight to the arms and hands (gure 9).
!
Warning :
- Position yourself as close as possible to the place where
you wish to sit.
- When transferring, position yourself as far back as possible
in the seat to prevent breaking screws, damaging the seat
upholstery or causing the wheelchair to tip forward.
- Lock the two brakes ; they should not be used in any case
as support for transfers.
- Never stand on the footrests when you are getting in or
out of the wheelchair (gure 10).

1.3 Tilting (balancing on the rear wheels)
For greater safety, this operation must be performed by an
attendant. The attendant should be aware of the required
physical effort and use appropriate positioning in order to
relieve the strain on his/her back (keep a straight back and
bend your knees during this operation).
To tilt the wheelchair, the attendant must rmly grab the han-
dles making sure both are properly xed. Warn the occupant
in the wheelchair before tilting it and remind him / her to
lean backwards and make sure that both feet and hands of
the user are clear of the wheels.
Place a foot on the footstep tube and move continuously
until the chair reaches the equilibrium point. At this stage, the
assistant will feel a difference in weight distribution, which
usually occurs at approximately 30°. At this point, the
wheelchair can get over the obstacle easily.
Finally, the attendant slowly and gradually lowers the front
down to the ground, while rmly holding the handles.
!
Warning :
- Be aware of detachable parts such as armrests or legrests :
they must NEVER be used as lifting supports as they may be
inadvertedly released, resulting in possible injury to the user
and / or attendant.
- Do not lower the wheelchair suddenly, even if it is several
centimetres from the ground, as this may result in injury of
the user.
1.4 Tilting, Kerbs
To get on the pavement :
- Method 1 (gure 11)
The attendant positions the wheelchair in front of the
pavement facing forward. Attendant tilts the wheelchair
backwards until the castors reach the pavement; attendant
pushes the wheelchair forward until the rear wheels are
against the kerb and again pushes the wheelchair until the
rear wheels climb over the kerb.
- Method 2 (gure 12)
In this case, the attendant stays on the pavement and
moves the wheelchair in a backwards position with the rear
wheels against the kerb. The attendant tilts the wheelchair
backwards until it is balanced and pulls the wheelchair with a
steady movement until the rear wheels climb over the kerb ;
then he / she lowers the castors, while making sure that the
chair is far enough on the pavement so that the castors do
not fall into empty space.

To get off the pavement :
The attendant positions the wheelchair facing forward on
the pavement and tilts it backwards until it is balanced, then
he/she pushes the wheelchair forward until the rear wheels
touch the road after getting over the obstacle; then, he / she
gradually lowers the castors to the ground.
1.5 Stairways
Because this is a difcult movement, we recommend using
two attendants, one in front of the wheelchair and one
behind the wheelchair.
To climb stairways (gure 13) :
After tilting the wheelchair to the point of equilibrium, one
assistant (at the back) holds the wheelchair up against the
rst step grasping the handles rmly to lift..
The second assistant, lifts the wheelchair above the stairs,
while holding rmly a xed part of the frame, and holds it
while the rst assistant takes a step and repeats the opera-
tion.
The wheelchair must not be lowered until the last step has
been passed and the chair is clear of the stairs.
To descend stairways :
Same operation as above, however, in reverse order.
!
Warning :
- Do not attempt to lift the wheelchair by any removable
parts (such as armrests, legrests or footrests).
- Avoid using an escalator which may lead to serious injury
in the event of a fall.
1.6 Slopes
It is recommended to avoid using ramps with a slope higher
than 9°. The wheelchair risks tipping over in the event of
spinning or side movement (gure 14).
13 14

Upward slopes (gure 15) :
Lean the upper body forward and move the wheelchair
forward with short quick pushes on the hand rims to main-
tain speed and direction control. If you want to rest, apply
both brakes when stopping.
Downward slopes (gure 16) :
Lean backward cautiosly and let the hand rims slide in your
hands. Be ready to react at any moment to control speed
and direction.
!
Warning :
- Avoid turning suddenly and never try to climb and descend
a ramp diagonally (figure 17).

2. Operating instructions
2.1 Unfolding and Folding the wheelchair
2.1.1 Unfolding the wheelchair (gure 18) :
- With one hand, grab the armrest or the seat support
tube on one side of the wheelchair and slightly tilt it to-
wards you (so that the rear wheel and castor lift from the
ground) ;
- With the other hand, push on the seat upholstery until
the tube supporting the upholstery is fully unfolded. The
seat upholstery must be fully extended ;
- Then, engage the two manual brakes, open the footrest/
legrest and check the ground clearance (footrest/ground
distance - see § B-2.1.5). You can now sit down in the
wheelchair.
