2. Preparation for use
The preparation for use of these devices must be performed by qualified
personnel both to evaluate the suitability of the product and to provide
the correct instructions to the user.
2.1 Wheelchair opening
•
Apply pressure with the open palm over the sides
of the seat (as shown on the drawing) until the seat
is perfectly aligned to the frame.
Be careful not to wrap the tubes of the
crossbar with your fingers to avoid being
pinched between the frame and the crossbar.
2.2 Wheelchair folding
•Fold up the foot-plate first to allow the folding of the
wheelchair frame;
•pull the seat upholstery upwards with both hands as
shown on the drawing.

7
2.3 Tyre pressure check
A periodical check of the tyre pressure may help to keep the wheelchair efficient and
more comfortable.
Verify the tyre pressure value according to the value marked on the tyre.
(Indicatively the maximum pressure is: 7.5 BAR for high pressure rear wheels, 4.5
BAR for 20'', 22'', 24'' x1.3 / 8 wheels and 2.5 BAR for pneumatic front castors.)
The pressure for the model Schwalbe Marathon Plus should always be kept from
a minimum of 7 BAR to a maximum of 9 BAR to prevent damage to the surface
of the tyre itself.
In case of air transport is recommended to decrease the tire pressure.
2.4 Rear wheels assembly check
ALTHEA wheelchairs are normally shipped with the rear wheels assembled.
Test for the right functioning of the quick release axle and proper assembly of the
rear wheels:
•
ensure the brakes are released;
•keeping the axle button pressed, pull out the
wheel from the hub;
•still holding down the axle button, insert it into
the hub on the frame of the wheelchair;
•check the efficiency of the engagement by
trying to pull out the wheel without pressing the
button and making sure it does not come off.
For safety reasons it is important to repeat this test every time that for transport
or maintenance reasons, the rear wheels are removed and reassembled to the
frame.

2.5 Foot-rest positioning
The ALTHEA wheelchair can be configured, depending on the model, with
detachable or not detachable footrests. According to the limits of setup, the footplate
can be either single (automatically lifted with the closing of the wheelchair), or both
single and double, manually lifted.
Once the wheelchair is open, position the footplate by rotating it downwards, ready
for use. If the footplate is single, pay attention to engaging properly its connection
pin to the corresponding connector on the frame.
Separate aluminium
profile footplates Single aluminium profile footplate
The automatic footrest, at the opening of the wheelchair, is automatically placed and
the footplate, in absence of weight, is slightly tilted on one side. This condition is
absolutely normal to allow the automatic closing. With a light weight on the plate, it
immediately takes a plain position.
In the case of a frame with removable footrests, the footrests are packed separately.
To insert the footrest:
•Open the wheelchair;
•Insert the footpads in their correct housing and rotate them starting from a 90°
angle position from the frame (as shown) and rotate it inwards until the
hooking mechanism snaps.

9
To extract the footrest:
•Press the hooking lever and rotate the footrest outwards
•Remove the footrest from the hinge pin by pulling it upwards
Note: If necessary, you can turn the footrest to the inside of the wheelchair.
2.6 Brakes check
To check the correct functioning and the efficiency of the parking brakes act as
following:
•
activate the brake (Fig. P, S);
•check if the wheels are blocked.
The included brakes, except for
optional drum brakes, have to
be used only as parking brakes and
never to decrease the speed of the
wheelchair while moving.
To ensure the efficiency of the brakes it
is necessary to maintain the proper tyre
pressure and check frequently the wear
of the clamping elements.

wheelchair is, and the further back it is assembled, the less active but the safest
the wheelchair becomes
• connect again the wheels to the chair checking the correct assembly (see par.
2.4)
• the operations always have to be performed symmetrically either left and right
side.
Be sure to choose the same position in both wheel bushes on the back of the frame.
Asymmetrical combinations produce instability.
Once changed the position of the back wheels, it is essential to adjust the front
fork perpendicularity (see. par.3.5) and the positioning of the parking brakes (see
par.3.7).
14
3.4 Front seat height adjustment
It is possible to vary the front height of the wheelchair by changing the diameter of
the front wheels or by choosing a different position of the wheel on the fork:

fork hole;
•
insert the “E” pivot, being careful to the original positioning of the “F”
spacers;
•fix the “D” screw.
Be sure to choose the same position in both wheels. Asymmetrical
combinations produce instability.
Once changed the front castor, it is essential to adjust the front fork
perpendicularity (see. par.3.5).
3.5 Front fork support plate adjustment
Once the front and rear seat heights are set, it is necessary to test and to adjust the
perpendicularity of the front fork support plate. This adjustment is important to
reach the maximum agility and the best driving sensitivity of the wheelchair.
•

•loosen the two “B” screws that secure the
fork support plate;
•rotate the upper eccentric nut until the
plate reaches the perpendicular position to
the ground;
•tighten the two “B” screws;
•place again the protective “A” cap.
Note: the two eccentric nuts have different profiles. The upper nut with round
profile allows a continuous adjustment of the plate perpendicularity. In the
lower position the hexagonal profile eccentric nut is assembled; it is
suggested to remove and rotate it only when the rotation of the upper nut on
its own is not enough to reach the correct position of the support plate.

15
3.6 Side guard adjustment
If necessary, act as follow to change the position of the side guards:
PLASTIC SIDEGUARD:
•remove the “A” and “B” screws;

In frames configured with straight rear frame, the unbalancing pedal is
integrated into the wheels for narrow passages support, so in case of
addition or replacement request it is necessary to replace the complete
support.
Under the same configurations, the unbalancing pedal is also used as a
support for the anti-tip device.
Curved rear frame unbalancing system:
In frames configured with curved rear frame, the unbalancing pedal is
an independent device connected to the frame using the same holes
available to fix the rear wheel plate.
It is not possible to select both the anti-tip device and the unbalancing
system on the same side.
10. Extended wheel plate
The standard rear wheel support plates can be replaced by special
extended wheel plates that increase the stability of the wheelchair
and meet some special requirements.
The back position of the extended wheel plate moves the centre of
balance in a very safe position. This special setup makes the
wheelchair more stable but less agile and more effort is needed to
push it.
11. Stretched bar
The stretched bar is a device added to the back-rest to keep the back frame stable
when the back-rest is very high, when the wheelchair is very wide or when the
configuration requires it for safety reasons or for choice of the user.
NOTE: OFF CARR reserves always the right to verify the technical compatibility of
the stretched bar with other characteristics of the wheelchair setup.
The stretched bar is always foldable to allow to fold the wheelchair for transport.

12. Elevating foot-rest
For safety reason the elevating foot-plate must be activated only by the
attendant.
For safety reason the return operation of the foot-rest, from high to rest
position, must be performed by the attendant acting simultaneously
with one hand on the activation lever and with the other hand
accompanying the descent of the foot-rest.
The foot-rest can be raised to create a continuous plane with the seat: this position is
unnatural for the patient so use it only when necessary.
Elevating foot-rest is only detachable.
13. Table
If the wheelchairs are equipped with armrests (tables cannot be attached to “L”
model armrests), it is also possible to select a table on the order form
The tables hollow are available in different materials and sizes:
Plastic table (grey): one size only-60 cm width
Soft padded table: S size (small)-50 cm width
M size (medium)-60 cm width
L size (large)-70 cm width
Transparent polycarbonate table: S size (small)-50 cm width
M size (medium)-60 cm width
L size (large)-70 cm width
There are several models of connection between the table and the armrest,
depending on the table, the armrest model and the elbow rest. Therefore,
in case of replacing, it is fundamental to specify the wheelchair serial
number, and the armrest, elbowrest and table models.
To equip a wheelchair with a table
•Loosen and remove the “A” screws that fix the elbowrest to the armrest;
•Mount the table support paying attention to its direction (right or left) and fix it
using 2 new screws 5mm longer than the removed
•Put the table supporting tubes in place and fix them to the preferred depth with
the “B” wing screw;
•Fix the supports to the table with the “C” screws.

To assemble the abductor:
•assemble on the wheelchair frame tube the holder;
•loosen without remove the set socket screw of the holding bar;
•assemble the holding bar by inserting the guide into the holder (pay attention to
the pommel) and fix the set socket screws;
•insert the abductor sliding support into its guide and fix it with the wing screw.
Remove only the abductor is possible acting on the wing screw, in this case the
holding bar remain assembled on the wheelchair that cannot be folded.
To fold the wheelchair is necessary remove the abductor and its holding bar:
•pull the pommel;
•take off the abductor and the holding bar.
30

•
to change the head-rest height act on the “A” wing screw;
•to move forward/backward the head-rest act on the “B”
wing screw;
•to change the direction of the head-rest act on the “C”
screws;
•when the desired position is reached fix properly all the
screws and wing screws.
17. Spokes guards
Spokes guards on real wheels prevent the user from putting accidentally hands or
fingers between the spokes of the wheels.
They can be attached to the spokes with velstraps or clips (it depends on the model).
18. WC seat
WC seat is a padded rigid seat with removable central part.
Under the seat there are two rails for the removable basin.
The toilet seat is removable to close the wheelchair for transport.
For functional reasons, the toilet seat is incompatible with sloping seat set-up. The
recommended maximum difference between the front and rear of the seat height
from the ground is 4 cm.
32
19. Use of the wheelchair
In order to move safely and properly use the wheelchair, it is always
recommended to consult qualified personnel.
Following there are some suggestions for a correct use of the wheelchair, also
aimed to maintain over time the characteristics of safety and durability:
•The brakes have only a parking purpose and should never be used as service
brakes to slow down the wheelchair in motion.
•To ensure the efficiency of the brakes, maintain the tyres properly inflated and
check quarterly the knurled locking pin wear.
•The arm-rests are not designed to lift the wheelchair.
•Never use anti-tip wheels as transit wheels.
•Do not lean too far forward to avoid fall-down.
•Always deal with slopes above 6° assisted by an attendant. This limit is only
approximate and it depends from the specific configuration of the wheelchair.
•The wheelchair should be used only for the transport of a person and not of
objects in general.
•Avoid wheeling the wheelchair without the supervision of an attendant.
•Prolonged contact of the wheelchair with water can cause unwanted oxidation of
some metal parts and decay of the security features of the materials involved.
•Avoid contact with seawater and sand, and in these cases proceed to an
immediate and accurate cleaning.
•Perform a general check of the wheelchair at least every three months, in
particular by checking tyre inflation, efficiency of the quick release axles and
brakes and lubricate, if necessary, the moving parts.
•Clean periodically the wheelchair using a damp cloth and avoid even partial
immersion of the frame. Keeping the wheelchair clean enhances its efficiency.

33
•The wheelchair can include among its parts some chromed metal components.
In case of allergy to chromium do not use the device and inform the supplier for
the required substitutions, if not already specified in the order form. Please
notify the company if allergies or other similar problems due to contact with
materials making up the wheelchair are developed.
•If needed, the upholstery can be washed with water at low temperature. In any
case, avoid wetting or submerging any other part of the wheelchair.
•Following the instructions of this manual, there is no evidence of danger of
injury during the opening and folding operations.
The pressure of the Schwalbe Marathon Plus tyres should always be
kept from a minimum of 7 bars to a maximum of 9 bars to prevent
damage to the covers themselves.
Keep the wheelchair away from heat sources, as not all coatings in the
order form are fireproof.
34
20. Warning to reduce the risks associated with misuse
of the wheelchair
Be careful not to wrap the tubes of the crossbar with the fingers to avoid
being pinched between the frame and the crossbar.
Do not use the brakes to slow down the speed of the wheelchair. They are
designed only as parking devices.
The arm-rests are not designed to lift the wheelchair.
Never use the anti-tip wheels as transit wheels.
It is suggested to verify the proper assembly and the efficiency of the quick
release axle before using the wheelchair and always after performing
releasing and re-assembly of the rear wheels to the frame.
The gap between wheels and side-guards or brakes could be lower than 2.5
cm. Be careful not to put your fingers between the wheels and side guards
or brakes to avoid injury.
To keep the wheelchair efficient and maintain its safety requirements is
suggested to perform regularly a maintenance program.
Poor maintenance and improper use of the device can cause damage or
injury to the user or assistant.
In case of transport by plane, it is recommended to reduce the tyre
pressure.
The wheelchair is not suitable for use in hyperbaric chamber.
Contact your dealer or the manufacturer to have more information about
connection points and devices needed to secure the wheelchair during
transport by car.
Before to transfer yourself in or from the wheelchair, always remember to
activate the brakes.

35
21. Maintenance, inspections and controls
Weekly:
Check the tyre pressure. Each tyre shows on the lateral bands the maximum
pressure for which they are designed. A flat tyre affects the efficiency of
brakes and the agility of the wheelchair.
Check the efficiency of the quick release axle and if necessary proceed with
the lubrication of axle and bushes.
Check the tension of the back-rest upholstery to maintain a comfortable
position.
Quarterly:
Check the tightness of the rear wheel support plate screws.
Check the tightness of the front fork support screws.
Check the wear of the front wheels.
Check the efficiency of the bearings on the rear and front wheels and on the
front fork support plates.
Check the efficiency of the brakes.
Lubricate moving parts such as quick release axles and bearings. It is
suggested to use silicon oil, which is efficient and doesn’t smear.
It is recommended to refer only to authorized and qualified personnel to perform
maintenance programs, adjustments, and components replacement on the
wheelchair.
