3. 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.
3.1 Opening/folding the back-rest
The wheelchair is sent with the rear wheels aside and with the backrest completely
tilted down.
OPENING
Pull the string to unlock the back-rest and pull
the back-rest upwards until the rear locks snap
in their locking places.
FOLDING
Pull the string to unlock the back-rest and push
it down until the rear locks snap in their
locking places.
3.2 Removing/Putting in place the rear wheels
Usually IDRA 2.0 are sent with the back wheels aside.
It is possible to assemble or release the wheels as follows:
• ensure the brakes are in released position;
• insert the shaft into the wheel hub by holding down the button;
• keeping the shaft button pressed insert it into the bush on the frame of the wheelchair;
• release the button;
• check the efficiency of the engagement by trying to pull out the wheel without pressing the
button and making sure it does not come out.

7
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 assembly of the
rear wheels to the frame.
Test for the right functioning of the quick release axle and proper assembly of the rear wheels:
•Ensure the brakes are released;
•
Keeping the shaft button pressed, pull out the
wheel from the hub;
•Still holding down the shaft 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 out.
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.
3.3 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.
Normally 7.5 BAR is the correct value for high-pressure rear tyres, and 2.5BAR is the
maximum pressure for front wheels if not solid. The above values are approximate as the
specific value is always available on every tyre.
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.

3.4 Brakes check
To check the correct functioning and the efficiency of the parking brakes act as follows:
•Activate the brake (Fig. P, S, U);
•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 necessa
ry to maintain the proper tyre
pressure and check frequently the wear
of the clamping elements.

4. IDRA 2.0 setup
The wheelchair is shipped in the configuration 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 technical restrictions it is still possible to perform other setup
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.
4.1 Changing the gravity centre
Adjustable axle IDRA 2.0 allows changing the gravity centre.
To change the gravity centre:
•Remove the back wheels by pushing the shaft
button (see
Par.3.2);
•Unscrew without removing the “D” screws;
•
Chose the most suitable position for the axle (there are
some appropria
te signs on the frame that make the axle
align correctly with the frame);
•Fix the “D” screws back;
•Once that the rear axle position is changed it is necessary to performe again the
cloth-guards and brake adjustments (par. 4.2 and par. 4.3).
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 more back the rear wheel axles are assembled, the more stable the wheelchair is, but
more effort is required to push it.
4.2 Setting the backrest tilt and clothes guards position
The backrest angle is adjustable:
•Unscrew without removing the “B” screws,
which fix
the carbon fibre wing to the aluminium support;
•
Remove the “A” screw by unscrewing the prevailing
torque which can be found under the seat;
•Change the backrest angle by choosing the most
suitable of the “F” holes matching the “A” connection
hole on the frame;
•Put back and fix not too thigth the “A” screw.

10
Once selected the backrest tilt, the position of the carbon fibre wing has to be
adjusted:
•Adjust the clothes guards position, making sure that the distance between the
clothes guards and the tyre stay around 6mm;
•Fix the “A” and “B” screws firmly.
4.3 Setup and maintenance of brakes
The supplied brakes are designed for parking only and they are not suitable to
reduce the wheelchair speed in any way.
If the rear wheel position has been changed from its original one, it is necessary to proceed
with the brake adjustment. IDRA 2.0 wheelchair can be equipped with classic pushing or
pulling brakes or scissor brakes.
Act as following to adjust the brake position:
•Leave the brake in OFF position (see par. 3.4 fig. O, R or T);
•Loosen without removing the “A” screws that fix the brake to its support and the “B”
screws that fix the support to the frame.
CLASSIC BRAKE:
•Move the brake on its support until the knurled
pin (feather) is about 10 mm far from the tyre;
•
Maintaining the knurled pin (feather)
perpendicular to the tyre, tighten properly the
“A” and “B” screws;
•
If the knurled pin (feather) appears worn in the
contact area wit
h the tyre, it is possible to turn
it to find a better contact area or to change it
with a new one;
SCISSOR BRAKES:
•Put the brake in ON position (see par. 3.4 fig.
U)
•
Move the brake along its support until it
touches the tyre;
•Return the brake in OFF position (see par. 3.4
fig. T) and move the brake of 3-
4mm, in the
wheel direction, then tighten properly
the “A”
and “B” screws;
•Verify the efficiency of the brake (see par. 3.4)
and if necessary repeat the adjustment procedure.
