Stability and equilibrium
To ensure that the wheelchair remains stable and is manipulated correctly, you
must always maintain good equilibrium. Many actions cause the user of a
wheelchair to reach out, lean over or move about within the wheelchair and
outside it. These actions will change your centre of gravity and weight
distribution of the wheelchair.
Your wheelchair has been designed to remain stable for normal everyday use
if it is used correctly taking the precautions recommended in this manual.
Position the castors to give the longest
possible wheel-base (Figure 2).
Lock the manual brakes on the rear wheels.
Leaning forwards
1.1 - Weight limit
(Figures 3, 4 and 5):
The maximum user weight limit for S & T models is 115kg and 100kg for
the SL & TL models.
This weight includes accessories such as a compact oxygen cylinder or other
equipment required by the user.
However, the wheelchair user's degree of activity is important. For example, an
active user weighing 75 kg may subject the wheelchair to more stress than a
user weighing 115 kg. We recommend very active wheelchair users to choose
an appropriate design of wheelchair. Your INVACARE approved distributor will
advise you on the best model.
1.2 - Reaching for an object
from a wheelchair
4
The limitations on reaching out from
a wheelchair shown in figure 1 have
been
produced
using
a
representative sample of wheelchair
users.
Only the ar ms should extend
beyond the seat of the wheelchair.
For safety reasons, the body and
head should remain within the
wheelbase.
3
Move the wheelchair as close as
possible to the object you wish to reach.
Only reach out to take what is within
arm's length in normal sitting position.

Leaning backwards
1.3 - Transferring to other
seats
9
(Figures 6 and 7)
Move the wheelchair as close as possible to object you wish to reach.
Only lean back for objects that are within arm's length in normal sitting
position.
6
7
It is possible to move from and to a
manually propelled chair if the
following guidelines are followed.
INVACARE does not recommend
any
par ticular
method
for
transferring:
This
is
the
responsibility of a medical adviser
who should consider your level of
disability and type of wheelchair .
10
When transferring, either to get out of
or return to your wheelchair, make
sure:
That the gap between the two seats is
as small as possible. (Figures 9 and 10)
Leaning to one side
(Figure 8)
8
This is the most dangerous manoeuvre as it is
easy to tip sideways.
To move up to the object and lean over, you must
use the castors as a means of keeping the
wheelchair stable and balanced. (Figure 2)
For your safety, it is essential to be in the
correct position.
That the manual brakes on the rear
wheels are on to prevent the wheels
moving. (Figure 11)
11
12
Turn both castors towards the seat to
which you wish to move. Lift up the
footplates .
Do not stand on the footplates .
Do not try to pick something up from the floor if
this would upset your balance.

13
Tilting without help from a third person
Wheelchairs in the INVACARE range have been designed for use by
those who have mastered the technique of balancing on the rear wheels
without help from a third person. However, you should never exceed the
limitations of the wheelchair. Repeated shock on the castors caused by
tipping the wheelchair up yourself may affect the rigidity or settings of
your wheelchair. If your wheelchair is fitted with accessories, these may
affect the methods used for balancing on the rear wheels.
When you wish to learn a new technique, consult an experienced person
for advice in using your type of wheelchair.
If possible, fold back the footrest
supports to the side to clear the
passage. (Figure 13)
14
If possible, remove the armrests on the
side between the wheelchair and the
other seat (Figure 14).
15
NB
Never stand up on the footplates.
(Figure 15).
8
1.4 - Tilting (balancing on the rear wheels)
Tilting with assistance from a third person:
The user should be sitting correctly and firmly in the chair or if unable to
support themselves, should be strapped in position to prevent him falling
out of the chair.
If a wheelchair user needs assistance in tilting the chair, the assistant must
know how to use his body correctly. Keep your back straight and bend at
the knee to tilt the wheelchair. Never exert too much force. The medical
team in charge of the user will advise you in the methods best suited to
your morphology. The INVACARE approved distibutor will provide you with
information on the risks of using the wheelchair incorrectly if the wheelchair
has removeable parts such as armrests or leg rests. These must NEVER
be used as aids when lifting as they may inadvertently become detached
and cause injury .
To tilt the wheelchair, a third person should grip the handles firmly. (Figure
16) Warn the user of the wheelchair
16
before tilting it and remind him/her to
lean backwards. Check that the user's
feet and hands are clear of all the
wheels. Place a foot on the foot step
tube and push smoothly until the
wheelchair is at the point of equilibrium.
At this stage, the helper will feel a
differ-ence in weight distribution which
usually occurs at an angle of about 30°.
Turn the wheelchair in the direction
required and negotiate the obstacle.
9
Lower the front of the wheelchair smoothly, holding the handles firmly. Use your
weight on the foot step tube to act as a counterweight. Do not lower the wheelchair
suddenly for the last few centimetres before returning to the normal position. This
might hurt the user.
1.5 - Kerbs or obstacles 30 to 50 mm high
17
10
Make sure that you get hold of
fixed, non-removable par ts only.
Use the following procedure for
going up stairs. (Figure 19):
Tilt the wheelchair to its point of
equilibrium. One helper (at the
back) holds the wheelchair up
against the first step, gripping the
handles firmly to lift.
19
The second helper, holding firmly a fixed part of the front frame, lifts
the wheelchair above the stairs and holds it while the first helper
places one foot on the following step and repeats the operation.
Method 2
(Figure 18)
The helper should stand on the pavement
and turn the wheelchair until the rear
wheels are against the kerb. Tilt the
wheelchair backwards to the point of
equilibrium and, in a continuous
movement, pull the wheelchair until the
rear wheels mount the kerb and pass
onto the pavement. Do not lower the
castors to the ground until you have
pulled the backrest of the wheelchair
sufficiently far to clear the kerb.
NB: Folding backs should always be
checked to ensure they are engaged.
We recommend that you take very great care when taking a wheelchair up
or down stairs. Two people are required for this.
ADVICE TO THIRD PERSONS
Method 1 - Negotiating the obstacle forwards
(Figure 17)
The helper should tilt the wheelchair
until the castors have passed over
the kerb. Move the wheelchair
forwards and lower the castors
gently onto the pavement. Push the
wheelchair until the rear wheels
touch the kerb. Lift and push until the
rear wheels have mounted the kerb.
Do not just lift by the handles on the
backrest.
1.6 - Steps, stairs or obstacles over 50 mm high
The wheelchair must not be lowered until the last step has been
negotiated and until the chair is clear of the stairs.
18
Escalators
Do not use an escalator when moving a wheelchair from one floor to another.
This might cause serious injury.
11
1.7 - Upward and downward slopes (operating limits)
Do not attempt to go up or down
slopes greater than 9% without
assistance. (Figure 20)
20
Downward slopes
23
Lean backwards carefully and allow the
handrims to slide through your hands.
Be ready to react at any moment to
check the speed and direction by
keeping in close contact with the
handrims. The manual brakes should
not be used to slow you down. (Figure
23)
If you are going up or down a slope
avoid turning sharply and never try to
go up or down diagonally.
2-Use
Always go straight up and down
slopes otherwise the wheelchair
might overturn. (Figure 21)
21
2.1 - Folding and unfolding the wheelchair
Wheelchair with fabric upholstery.
To fold
Lift the footplates .
Release the backrest tensioner if necessary.
Using both hands, take the centre of the seat fabric at the front and back
edges and raise it. (Figure 24).
Or, tilt the wheelchair to one side and close it using the handles on the back
rest or the armrests. (Figure 25).
Upward slopes
Lean the upper part of the body
forward and push the chair forward with
short quick thrusts on the handrims to
maintain speed and control direction. If
you wish to take a rest, apply both
brakes when stopping. (Figure 22).

The rear wheels have a diameter of either 600
mm, 550 mm, or 500 mm. They are equipped
with spokes and handrims. They can have
pneumatic tyres or solid tyres and can be
connected to the side frame by means of a
fixed axle or a quick release axle.
Tyre pressure.
The pressure is shown on the tyre and must never be exceeded. The
maximum permitted pressure is 450 kPa (65 PSI - 4.5 bar).
Remember that the tyre pressure on both wheels should be the same
to ensure perfect steering.
In case of a puncture, the tyre has to be removed from the rim. Press
the valve to let all the remaining air out of the inner tube. Pull the tyre
off the rim. Repair or replace the inner tube. Put the tyre back on the
rim. Inflate the tyre to the required pressure.

10. Castors
- Note: It may be necessary to use one or two tyre removal tools (not
supplied).
Front wheels
- The front wheels have a diameter of either 190mm or 125 mm
available in solid puncture-proof tyres only.
No adjustment is necessary for the front wheels.
Warning
Applicable only to chairs fitted with 24" wheels.
These chairs are assembled with the wheels set in the rearward
position. It is important that the chairs are not re-configured with the
wheels set in the "forward" position; this would allow the footrest
hangers to disengage the brake levers when swung away from their
locked position, causing the chair to become unstable.
Forks
