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

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.

8
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.

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;

11
•insert the rear wheels and check the distances between them (d1and d2),
measured on the front and on the back at the level of the hub as shown in the
figure; d1 and d2 have to be equal.
•check the “c” distance from frame to wheel and verify if it is equal both
on the left and on the right side;
•once the necessary corrections have been performed and all the above tests
are passed, tighten properly the “C” nut that secures the bushes to the holding
plates.

12
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:
•unscrew completely one of the “D” screws and remove
the “E” pin, on the side of the non-removed “D” screw,
paying attention to the positions of the “F” spacers;
•if necessary, change the wheel;
•position the wheel hole in level with the most suitable
fork hole;
•insert the “E” pivot, remembering the correct positioning of the “F” spacers;
•fix the “D” screw.
Be sure to choose the same position in both wheels. Asymmetrical combinations produce instability.
After changing the front castor, it is extremely important 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.
•remove the “A” protective cap;
•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;
•Reposition the protective “A” cap.
Note: the two eccentric nuts have different profiles. The upper nut with a round profile allows a continuous adjustment of the
plate perpendicularity. The hexagonal profile eccentric nut is assembled in the lowest position; 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.

13
3.6 Back-rest tilt adjustment
The back-rest tilt angle is fixed according to the choice on the order form. It is however possible, if allowed by the chosen
configuration, to change it if required.
•remove the “A” screw;
•select the new position of the back-rest;
•insert and tighten the “A” screw.
NOTE: if the choices in the “A” area are not enough it
is possible to act also in the “B” area to extend the
adjustment range.
3.7 Side guard adjustment
If necessary, act as following to change the position of the side guards:
PLASTIC SIDEGUARD:
•remove the “A” and “B” screws;
•choose the new desired position of the side
guard considering that the ideal gap between it
and tyre is about 6 mm;
•tighten the “A” and “B” screws being careful
to the original positioning of the washers and
spacers.
ALUMINIUM SIDEGUARD:
To allow a gradual adjustment, the aluminium
clothes guards is fixed through the "A" and "B"
screws to some dedicated slots on the frame:
•unscrew without removing the “A” and “B”
screws;
•choose the new desired position of the side
guard considering that the ideal gap between it
and the tyre is about 6 mm;
•tighten the “A” and “B” screws.

14
3.8 Brakes adjustment and maintenance
The supplied brakes are designed for parking only and they are not suitable to reduce the wheelchair speed.
If the rear wheel position has been changed from its original one, it is necessary to proceed with the brake adjustment.
Act as following to adjust the brake position:
•leave the brake in OFF position (see par. 2.6 fig. O or R );
•loosen without removing the “A” screws that fix the brake to its support and the “B” screws that fix the support to the
frame.
•move the brake on its support until the “C”
knurled pin is about 10 mm far from the tyre;
•tighten the “A” and “B” screws while keeping the
“C” knurled pin perpendicular to the tyre;
•if the “C” knurled pin appears worn in the contact
area with the tyre, it is possible to turn it to find a
better contact area or to change it with a new one;
•Verify the efficiency of the brake (see par. 2.6) and if necessary repeat the
adjustment procedure.
3.9 Seat upholstery adjustment an replacement
The seat tension can be adjusted by acting on the velstraps:
