1. Introduction
The ultra-lightweight wheelchair DIVA is a non-intrusive medical device, specifically designed to reduce and counterbalance a
physical handicap.
This wheelchair is manually propelled on the back wheels, has many setups and a wide range of accessories that meet any
customer need.
Only qualified operators must setup the device.
It is forbidden to use the wheelchairs or parts of them in different ways from those described on this manual.
1.1 Description
DIVA is an aluminium folding frame wheelchair. Other details are made with aluminium, steel alloys or composite materials,
such as carbon fibre.
Various frame colors are available and can be combined with various anodized accessories and details sets.

5
The seat upholstery (3) and the back-rest (5) are usually made of black nylon cloth. The back-rest can be also made of
breathable material to increase the customer’s comfort. The back-rest upholstery is easily removable to make the cleaning and
washing operations easier and its straightening is adjustable by acting on the velstraps under the upholstery.
A comfortable compartment with closing zip can be added in the lower part of the back-rest and another can be placed frontally
under the seat.
The back-rest is adjustable in height by acting on the frame-fixing screws. On request, the wheelchair can be equipped with a
tilt-adjustable back-rest.
Different rear frame shapes are available (with setup limitations). The rear wheel plate (6) allows an easier adjustment of the
rear wheel position to find the most comfortable setup for the user. On demand, for special needs, the wheelchair can be
equipped with an extended wheel plate for safer setup. In this case, the reclining back-rest is compulsory.
20” or 22”or 24” rear wheel (RW) are available, with some setup restrictions. All rear wheels are equipped with the quick
releasing axle.
The front forks (9) have adjustable angles and can hold various wheel diameters (FC) at various heights, to better answer the
setup and agility needs of all users.
The front frame (7) is available with fixed or detachable foot-rests. Considering possible setup restrictions, the foot-plates (11)
can be single or double and adjustable in height and angle. Foot-holding belts and heel stops are available.
The wheelchair can be equipped with closed arm-rests or with open arm-rests with side guards. Different kind of arm-rests are
available. With open arm-rests or without arm-rests the wheelchair is provided with composite polymer side guards or with
aluminium side guards, as chosen on the order form.

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.
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 Schwalbe Marathon Plus model 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 tyre pressure.
2.4 Rear wheels assembly check
DIVA 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:

7
•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 DIVA 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).
Rotate them 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.

2.7 Accessories check
Any accessory required at the time of the setup of the wheelchair is to be shipped separately. If so it should be properly installed
before using the wheelchair.

3. Setting up
The wheelchair is shipped in the setup chosen on the order form. The selected options in the order form should ensure the best
possible setup to match the customer needs. Considering potential setup restrictions it is still possible to perform other
adjustment to better fit the user’s needs.
Please refer to authorized and qualified personnel only to perform any type of adjustment on the wheelchair.
3.1 Rear seat height adjustment
•By pushing the axle button pull out the rear wheel from the
frame;
•Lean the wheelchair on its side;
•remove the “A” screws;
•move the inside threaded insert in the chosen position;
•fix the “A” screws.
3.2 Gravity centre adjustment
The further the rear wheels axles are assembled, the more active and agile the wheelchair becomes, but at the same time the
stability is reduced.
The further back the rear wheel axles are assembled, the more stable the wheelchair is, but more effort is required to push it.
•By pushing the axle button pull out the rear wheel from the
frame;
•loosen the “C” nut and remove from the rear plate the “D”
wheel bush;
•select the new position for the bushes between the three “B”
holes available, keeping the original sequence for spacers and
washer.
Note: consider that the further the hub is connected, the more
agile the 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 both
on 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.
After changing the position of the back wheels, it is essential to adjust the front fork perpendicularity and the positioning of the
parking brakes.
3.3 Rear wheel chamber adjustment
The rear wheel camber is fixed according to the choice on the order form. It is however possible to change it if required.
On DIVA wheelchairs it is possible to change the wheel camber by replacing the rear bushes as follows:
•remove the rear wheels;
•unscrew and remove the “C” locking nut;
•replace the ”D” bush with a new one of the desired camber;
•place the “D” bush with the required camber in the correct
direction and the two flat surfaces approximately
perpendicular to the ground;
•insert the “C” washer and nut keeping it loose in order to be
able to perform a fine adjustment of the wheel camber;
