Introduction
Dear Customer
Thank you for purchasing an Invacare wheelchair.
This model was designed to provide you with all the benets and features to meet your needs.
Only quality components were selected for your wheelchair based upon rigorous inspections during the
entire manufacturing process.
This product conforms to the requirements of Council directives 93/42/EEC related to medical devices
class 1(one) product by application of following standards: NF EN ISO 14971 and NF EN 12182.
This manual describes the operating limits of your wheelchair, maintenance operations and adjustments
that you or your assistant can make.
However, all the repairs (except for inner tubes) as well as some adjustments, require specic technical
training and, therefore, must be performed by your distributor.
The Invacare® Action4® is designed for both indoor and outdoor use with the purpose of helping people
who are not able to walk over a long distance.
Even though your Invacare® wheelchair has been designed to provide a long and trouble free life it is
inevitable that wear, tear and usage will eventually render the product unusable. Invacare® recommends
that the average usable life of this product is ve years, providing the product has been correctly
maintained according to the manufacturers recommendations.

whilst the line of your combined centre of gravity lies within
the points of contact of the forward and rear wheels with
the ground.
- Weight Limit
The maximum recommended weight of the user is 125kg
and 150 kg for 50,5 - 55,5 & 60,5 cm seat width. 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 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 parame-
ters 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 transfer
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. Any movement you make whilst sat in your wheelchair
will move the combined centre of gravity of you (Gc) and
the wheelchair (Gw). You will remain stable in the wheelchair

4
5
1.1.1 Leaning forward
Do not extend your chest beyond 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).
!
Warning :
The hanging of back packs or similar items onto your chair
backposts can affect the rearward stability of your chair,
especially when used in combination with recliner backrests.
This can cause the chair to tip backwards causing injury.
Therefore, Invacare® strongly recommend the use of anti-
tippers (available as an option) when using your backposts to
carry a back pack or similar items.

1.2. Transferring to other seats
1.2.1 Sideways transfert
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.
Fold the footplate up and push the footrest/legrest to the
side, remove / swing away the armrest to falicitate the
transfert.
Shift your body towards the place where you want to sit
while distributing your weight to the arms and hands
(gures 8 & 8A).
- While moving from the wheelchair to the seat, your body
will have little or no support. Where possible use a transfer
board during transfers.
1.2.2 Front transfert (gure 9)
If you are more or less able to stand up and if your upper
body is strong and mobile enough, you can transfer forward
to another seat.
If you nd this movement difcult, we recommend that you
obtain some assistance from an attendant or carer to ensure
the transfer is as smooth and safe as possible.
Lock both brakes and ensure both castor wheels are facing
the forward position.
Please note that the brakes should not be used in any case as
support for transfers. Fold the footplate up, then grip rmly
the armrest handle, take care of your nails on the skirt-guard
edges. Push on your arms to easily lift yourself up and the
attendant can help you to nalise the transfer to the place
where you wish to sit.
!
Warning :
- Position yourself as close as possible to the place where
you wish to sit.
88A 9

- 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 equi-
librium 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
inadvertently 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 pave-
ment facing forward. Press down on the lower tube of the
frame (or on tipping levers, delivered as an option) as well
as pulling on the push handles. 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.
11
10

6
7
- Method 2 (gure 12)
In this case, the attendant stays on the pavement and tilts
the wheelchair in a backwards position with the rear wheels
against the kerb. The attendant tilts the wheelchair bac-
kwards 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.
!
Warning :
we recommend that users over 100 kg in weight do not use
this starway manoeuvre !
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, reverse steps as above.
!
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).
Upward slopes (gure 15) :
Lean the upper body forward and your centre of gravity will
move forward to a more stable position. Now move the
wheelchair forward with short quick pushes on the hand
rims to maintain speed and direction control. If you want to
rest, apply both brakes when stopping.
Downward slopes (gure 16) :
Lean backward cautiously and your centre of gravity will
move backward to a more stable position. Now 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).
1817
The position of the rear wheel axle and the angle of your
wheelchair’s backrest are two of the key adjustments
that can affect your stability whilst sat in the wheelchair
(see gure 14A). It is recommended to avoid using ramps
with a slope greater than 9 degrees and do not attempt
to turn whilst on a slope. The wheel position is usually
factory set and should not be change unless by the
direction of a competent person who must have assessed
the impact of the change on your stability in normal
use. If your wheelchair is tted with a recliner backrest
it is recommended that anti tippers are also tted and
used whenever the backrest is reclined from the upright
position.
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 tube until the
upholstery is fully extended and seat tube sits in receiver.
- Then, engage the two manual brakes, open the footrest/
legrest and check the ground clearance (footrest/ground
distance - see paragraph B-2.1.4). You can now sit down in
the wheelchair.
2.1.2 Folding the chair (gures 19 & 20) :
- Fold and lock the footrest/legrest toward the front of the
wheelchair.
- Swivel the plates into the vertical position. Using both
hands, take the centre front and back edges of the seat
upholstery and lift it. Or, tilt the wheelchair to one side
and close it using the handles on the backrest.
!
Warning :
- Fold the wheelchair while keeping the seat upholstery
upwards to avoid damage by the folding system.
- Caution possible finger pinch.
2.2. Wheelchair propulsion
Self propelling wheelchair propulsion is achieved through the
use of the handrims mounted on the wheels.
The distance between the wheels axle position and the seat
height can be adjusted to allow you to hold the handrims
properly, and various accessories can be added to improve
the grip (anti-slip plastic coated, etc.). Qualied medical and
paramedical staff will be able to provide you with advice
regarding the propulsion which is best adapted to your
disability. Any wheels adjustments to the set up of your
wheelchair (see paragraph 2.2.2) should only be performed
at the direction of a competent person who has fully risk
assessed the implication of any changes to the wheelchair
conguration.
2.3. Lifting the wheelchair
First folds the chair (see paragraph 2.12), always lift the
wheelchair by gripping the frame at the points (A) shown in
the gure 21.

3. Safety inspection and maintenance
3.1. Performance control
As the user, you will be the rst to notice any possible
operational defects with your wheelchair. The following table
indicates the easiest troubleshooting symptoms to identify
and the preliminary inspection that you can perform.
In the event that the symptoms persist after adjusting the
pressure in the tyres and tight screws and nuts, please con-
sult your retailer.
The inner tubes of the wheels are the only components that
you can repair yourself (see paragraph B-2.3).
If the screws and nuts are not tight enough or loose, the axle
fork angle is not perpendicular to the ground, please consult
your retailer to get a competent person to re-set them to
the correct position and tighten appropriately.

4.1. Observations before transport of wheelchairs in
vehicles
• We recommend that wheelchair users should transfer to the
seat of the vehicle and use the installed restraint system of the
vehicle whenever feasible.
• The wheelchairs are tested in a basic conguration. The use
in other congurations has not been tested. Please contact
your dealer for further information.
• Auxiliary wheelchair equipment is either secured to the
wheelchair or removed from the wheelchair and secured in
the vehicle during transit. (i.e. table trays).
• Alterations or substitutions are not to be made to points of
the wheelchair or to structural and frame parts without the
written consent of Invacare®.
• A wheelchair-anchored posture belt with metal buckle must
be tted across the wheelchair occupant in addition to the lap
and diagonal occupant restraint (3-point belt).
• Belt restraints are not to be held away from the body by
wheelchair components or parts such as armrests, postural
restraints, wheels, etc. (Picture 22)
• The wheelchair must be securely fastened in the vehicle with
an ISO 10542-2 approved 4-point belt system, according to
the methods described in the manual.
• The occupied wheelchair must be tied down in an forward-
facing conguration, with the parking brake applied.
• The wheelchair backrest should be positioned as close as
possible to 90 degrees.
Please observe that even if these products and recommen-
dations are provided in order to increase safety, injury to
vehicle occupants still might occur in the event of a collision
or other accidents and no guarantee is given in this respect.
Correct and incorrect placements of 3-point belt (picture
22)
4.2. Restraint systems (picture 23)
* Non contractual picture, only for information !
Please refer to best practice recommended instructions
from the safety belt manufacturer.
A. Frontal restraints with straps
1. Connect the frontal straps around the frontal part of the
frame. (See location of the attachment labels).
2. Release brakes and tension front straps by pulling the
wheelchair backwards from the rear.
3. Re-apply wheelchair brakes.
B. Rear restraints
1. Attach the snap hooks on the rear straps to the frame
just above the rear wheel attachments. (See location of the
attachment labels).
2. Tighten the straps.

12
13
C. Posture belt
1. The posture posture belt is mounted on the back frame
(picture 23).
2. Check that the posture belt on the wheelchair is correctly
fastened. If posture belt on the wheelchair is missing we
recommend that the user should transfer to the seat of the
vehicle, if possible. The posture belt should be used in addi-
tion to but never as a substitute for an approved passenger
restraint system (3-point belt).
D. Fastening of 3-point belt (vehicle safety belt device).
Although all three points may be anchored to the vehicle
oor, the diagonal belt passing over the users shoulder should
be routed through a point above and behind the seated user
which is xed to the vehicle sides, before passing down to
the oor. The 3-point belt should not be kept from the user's
body by the parts of the wheelchair.

B. DESCRIPTION OF YOUR WHEELCHAIR
1. PRESENTATION
1.1. Introduction
Your wheelchair has been factory set before you purchased
it. However, it must be specically adapted to your needs.
The following detailed paragraphs describe the various
functions and possible adjustments as well as available
options. You can make some adjustments yourself, while
others can be made only by your dealer.
Important: based upon the selected model or options, your
new Action4 wheelchair may be not equipped with all of the
components or options which are described in the
following pages.
!
This is a warning symbol, it is essential that the
instructions in these paragraphs are followed in
order to prevent personal injury to yourself and
others around you.
iThis is an information symbol about possibility
to contact your Dealer for more information.
1.2. General description (see photo)
Your wheelchair is made of various parts and this manual
describes only the main parts. We recommend that you
become acquainted with the following terms in order to
better understand your wheelchair operation :
 The seat consists of the seat and backrest upholstery,
the backrest and armrests. This unit is designed to provide
optimal comfort.
 The swing-away footrest support or legrest : this
is the supporting part between the frame and the footrest
which swivels to facilitate transfers and can be removed
during transport.
 The footrest consists of an adjustable tube and the
footplate which supports the foot.
 The folding frame consists of side frames and a folding
system including the seat rails. These parts constitute the
frame, which is the supporting component of the wheelchair
and its strength is well tested (checked at 125 kg and 150 kg
for 50,5 - 55,5 & 60,5 cm seat width ).
 The steering tube is the connection between frame and
castors ; it allows the adjustment of the seat angle.
 The rear wheel consists of the wheel, axle and handrim.
The position of the rear wheels relative to the seated user
determines the rearward stability and also the ease by wich
the user can propel the wheelchair using the handrims. They
are mounted on the multiple adjustment wheel support
brackets .

16
17
 The castor consists of the front wheel and the fork. The
castors provide front contact with the ground and determine
the steering by the direction of the forks.
 The manual brake is a parking brake. The two manual
brakes are used to secure the wheelchair when stationary.

• Nylon upholstery seat with or without Velcro fastener : the
Velcro fasteners are required for the proper positioning of
the cushion (photo 1) ; please make sure that the cushion is
properly positioned on the seat.
• Padded seat : it provides comfortable support to the user.
i Standard seats are not adjustable; in the event that they
become slack, it is recommended to request your dealer to
replace them.
!
Always use upholstery equipped with Velcro fasteners
when you have a cushion in order to prevent sliding. Adding
a cushion to the seat will raise your height above the ground
and can affect your stability in all directions. If a cushion is
changed it may also change the users stability.
i Invacare provides a wide range of seat cushions adap-
ted to your needs. Please contact your dealer.

• To save space when transporting folded and unoccupied,
operate lever (B) by pulling or pushing it and fold the top of
the backrest. To return to the initial position, bring the top in
the vertical position; it locks automatically.

Always make sure that the backrest is properly locked
in place before the user settles down in the wheelchair to
prevent any injuries !
- Reclining backrest 0° - 30° - 39/41/43 cm (short cane tube)
or 47/49/51 cm (long cane tube) backrest height.
The intended use of reclining backrest is to get a relaxing,
comfort position for the user. It is not indented to be used
in a dynamic situation and it should be used on horizontal
surface when the backrest is reclined (especially when the
backrest angle is more than 10°). Anti-tippers are recomman-
ded for those who need to feel safer or have a specic usage.
Simultaneously pull the levers (A) to provides the same angle
on both sides, release the levers when you reach the desired
angle.(photo 4)
 Mechanical version
There are 4 angles position by step of 10°.
Note : Push on the backrest canes before operating the
levers, this is to release the auto-locked security system.

 Gas strut version 0° to 30° continuously 43 cm (short cane
tube) or 51 cm (long cane tube) backrest height. (Photo 6).
The gas struts provide a help to the attendant to raise the
user, always operated with the user seated in the wheelchair.
!
It is recommended that this operation be performed
only by the attendant. Always make sure that the backrest is
locked in place to ensure perfect safety for the user.
Keep away ngers from moving parts (levers, cylinders,
mechanisms, etc.) to prevent injuries !
The backbrace (B) (photos 6 & 7) links the two push handles
and must always be in position on recliner versions (see para-
graph 2.6.1).
Avoid operating levers (A) (photo 7) during a sideways transfer,
for example, in order to prevent destabilising the user’s posi-
tion ! To ensure safety for the user, when backrest is reclined,
we recommend to use anti-tippers (available as an option).
i Maintenance of reclining backrest mechanism varies with
use. Please contact your Dealer.
Based upon the development of your disability, you can choose
an Action4 backrest that meets your needs. Please consult
with your Dealer.
!
If you consider there is an excessive free play in the
recliner mechanism after a simple visual examination of the
ratchet, please contact your Dealer.
To ensure safety for the user, when backrest is reclined, we
recommend to use anti-tippers (available as an option).
!
The hanging of back packs or similar items onto your
chair backposts can affect the rearward stability of your chair,
especially when used in combination with recliner backrests.
This can cause the chair to tip backwards causing injury.
Therefore, Invacare® strongly recommend the use of anti-
tippers (available as an option) when using your backposts to
carry a back pack or similar items.
