Machine description
2.1 PURPOSE
It is used to balance the wheels of cars, vans, 4-WD, mo-
torcycles and scooters. The wheels must weigh less than
75 kg. and, when fitted on the balancing machine, must
not interfere with any fixed part of the machine, excluding
the shaft and support adaptor. It can be operated in the
temperature range of 0° to + 45°C.
The machine is supplied with equipment enabling the
vast majority of car wheels available on the market to be
fitted. Other wheels with special dimensions, geometry
and centring require special adaptors supplied on request.
The machine can operate only on at non resilient oor.
To lift the machine, lever only on the base where the 3
support points are located. never, under any circustance,
apply force to other points such as the spindle, head, or
accessory shelf. It functions properly without having to
fasten it to the floor with wheels weighing up to 35 kg; for
heavier wheels, fasten it at the points indicated. Do not
mount anything other than motorbike, car or truck tyres
on the wheel balancer.
Thanks to the new and exclusive VDD (Virtual Direct Drive)
system, reliable unbalance measurements can be made
in a short time, almost half the time of the cycle used with
respect to other balancers in this range.

5.1 PRESETTING OF WHEEL DIMENSIONS
The balancing data is set by means of an “intelligent”
automatic gauge; conrmation of the measurement and
the position appear on the display. Each time the gauge
is pulled out, the rim interior light comes on (if enabled) to
illuminate the inside of the rim so that it is easier to select
the correction planes.
5.1.1 Automatic standard setting
Using the special grip, move the gauge against the rim
as shown in the figure:
While the gauge is moving the following appears:
Hold the gauge in position for at least 2 seconds.
If the acoustic signal is enabled ( ACOUSTIC SIGNAL),
the acquisition of the dimensions is accompanied by a “beep”.
Measurement stored:
Use of the wheel balancer
Set the distance and diameter gauge to the rest position.
The balancing machine automatically interprets the pre-
sence of a rim with clip-on weight correction:
For a different combination of the type or position of the
weights on the rim, press the buttons near the rim symbol
(CORRECTION MODES).
5.1.1.1 Automatic width (option)
At the end of the automatic measurement of the distance
and diameter the following appears:
For large wheels (e.g. off-road vehicles, light trucks or
wheels protruding far out from the rim) press the
button to switch from:
N.T. = NORMAL TYRE
L.T. = LIGHT TRUCK
5.1.2 ALU wheel automatic presetting
Make two consecutive measurements within the rim on
two correction planes inside the same.
When the acoustic signal is enabled ( ACOUSTIC SI-
GNAL), the acquisition of the dimensions is accompanied
by a “beep”. Set the distance and diameter gauge to the
rest position.
The balancing machine automatically interprets the pre-
sence of a rim with adhesive weight correction:

5.2 MEASUREMENT RESULT
After performing a balancing spin, the unbalance values
are shown on the displays 1-2. The symbol indicates
the correct angular position of the wheel in order to apply
the counterweights (12 o’clock for clip-on weights; 6 o’clock
with laser indication for adhesive weights to be applied
inside the rim). In this case, the rim interior light (if ena-
bled) stays on to facilitate rim cleaning and subsequent
application of the correction weights.
If the wheel clamp option is enabled ( MENU), the
wheel is automatically clamped in the correction position.
Pressing the chuck can be locked/released in any
position to facilitate mounting the wheel ( MENU).
If the unbalance is within tolerance, 0 (zero) is display-
ed; pressing , you can read the values below the
required tolerance threshold.
5.3 WHEEL LOCKING
The wheel is automatically locked when reaching the correct
angular position for weight application on the inside and
outside, turning it slowly by hand. To unlock the wheel, turn
it hard to move it from the correct correction position.
If the unbalance is within tolerance, the wheel is not
automatically locked. By pressing the button it
is possible to lock/release the spindle in any position to
facilitate the wheel assembly.

To cancel the function, press the button again.
5.5 SPLIT FUNCTION
(hidden weight)
The SPLIT function is used to position the adhesive weights
behind the wheel spokes (angle >18°) so that they are no
longer visible (for alloy rims). Use this function in the ALU
or STATIC mode where the adhesive weight is applied to
the outer side of the rim.
▪Perform an unbalance measurement spin.
▪position the unbalance to be split in the correction
position in order to turn on the laser.
▪Press and hold the button until the laser
points to the spoke you wish to correct.
▪Release the button .
▪Turn the wheel in the rotation direction indicated by
the positioning arrows until the second spoke is in the
position indicated by the laser and press
.
▪Position the wheel as indicated by the LEDs. The
unbalance is indicated on the display.
To return to the normal unbalance indication press
.
The spoke-to-spoke distance must be a minimum of
18° and a maximum of 120° (if not, errors 24,25,26 ap-
pear). Spokes with irregular or inconstant angles can be
compensated.
If the laser is disabled ( MENU), operate as follows:
▪Turn the wheel to the correction position of the unba-
lance to be split.
▪Move one of the spokes where you want to split the
unbalance to 12 o’clock (e.g. 1) and press .
▪Following the rotation direction indicated by the posi-
tioning arrows, move spoke 2 to 12 o’clock and press
. The value to use for correction in posi-
tion 2 is displayed.
▪Position the wheel on spoke 1 following the positioning
arrow indicator and correct the unbalance as indicated

5.6 AUTOMATIC MINIMIZATION OF STATIC
UNBALANCE
This program is designed to improve the quality of balancing
without any mental effort or loss of time by the operator. In
fact by using the normal commercially available weights, with
pitch of 5 in every 5 g, and by applying the two counterweights
which a conventional wheel balancer rounds to the nearest
value, there could be a residual static unbalance of up to 4
g. The damage of such approximation is emphasized by the
fact that static unbalance is cause of most of disturbances
on the vehicle. This new function, resident in the machine,
automatically indicates the optimum entity of the weights
to be applied by approximating them in an “intelligent” way
according to their position in order to minimize residual static
unbalance.

When optimisation is complete, perform a new spin or press
the button to return to the measurement screen.
6.3 SELF-DIAGNOSTICS
The machine can perform self-diagnostics to check the
LED’s on the control panel and make sure the encoder
reads correctly.
To perform this operation, view the SETUP menu.
In the self-diagnostics sequence, all the LED’s on the pa-
nel light up for a few seconds in order to check operation.
When the LED’s go out, the machine automatically moves
on to the encoder reading phase. When the wheel is turned
manually (forwards and backwards), the display shows its
exact position. The value lies between 0 (zero) and 255.
(Consult the extraordinary maintenance manual or
contact Technical Service).
6.4 CALIBRATION
To calibrate the machine, proceed as follows:
▪Fit an average size wheel with a metal rim on the shaft.

7. Diagnostics
7.1 INCONSISTENT UNBALANCE
READINGS
In some cases, when a wheel that has just been balanced
is repositioned on the balancer, the machine can detect
an unbalance.
This is not a machine problem but is due to faulty mounting
of the wheel on the flange. In other words, when mount-
ing the wheel after initial balancing, it has taken another
position with respect to the balancer shaft axis.
If the wheel has been mounted on the flange with screws,
the screws may not have been tightened correctly (criss-
cross sequence) or the tolerances of the holes drilled in
the wheel may be too large. Small errors, up to 10 grams
(0.4 oz), are to be considered normal in wheels locked
with the relative cone: The error is normally greater for
wheels locked with screws or studs.
If, after balancing, the wheel is still unbalanced when re-
fitted on the vehicle, this could be due to an unbalanced
brake drum or, very often, the tolerances of the holes
drilled in the rim and drum are too large. In this case,
balancing should be performed using a balancer with the
wheel mounted on the vehicle.
7.2 ALARM SIGNAL
The machine has a self-diagnostics cycle which identi-
fies the most frequent malfunctions during the normal
work cycle.
These malfunctions are processed by the system and
shown on the display.

As extraordinary maintenance must be performed by service
staff or, in any case, by specifically authorised and trained
people, is not dealt with in this manual.
8.1.2 Safety rules
Performing specialist activities on the equipment, particularly
if the guards need to be dismounted, exposes people to
serious danger due to the presence of potentially live parts.
The rules shown below must be scrupulously followed.
People must always use the Personal Protective Equip-
ment indicated in the Installation Manual. During activi-
ties, unauthorised people may not access the equipment
and WORK IN PROGRESS signs will be erected in the
department in such a way that they are visible from every
place of access.
8. Maintenance
Specialist staff must be authorised and especially trained
concerning the dangers that may arise during operation
and the correct methods for avoiding them.
They must always work with great care and pay full at-
tention.
If, exceptionally, the staff removes the guards to carry out
a particular specialist technical maintenance, inspection
or repair job, they are required to put them back after
work.
After work, staff must make sure that foreign objects, in
particular mechanical pieces, tools or devices used dur-
ing the operative procedure that could cause damage or
malfunctions are not left inside the balancer.
For safety, before starting work, maintenance, inspection
and repair staff must disconnect all power sources and
take all the necessary preventive safety measures.
As well as operating frequencies, the operations described
below indicate the qualifications that staff must possess
in order to perform the operation.
8.1.3 Replacing fuses
Some protection fuses are located on the power board
(see wiring diagrams) accessible by dismantling the weight
shelf). If fuses require replacement, use ones with an
identical current intensity.
