2.1 PURPOSE
It is used to balance the wheels of cars, vans, 4-WD, motorcycles 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.
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.

▪ machine settings menu.
▪ touch panel
▪ adhesive weight positioning laser
▪ rim interior light
▪ wheel locking
▪ automatic width
▪ radial eccentricity measurement

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.

5.10 ECCENTRICITY MEASUREMENT
5.10.1 When and why matching
The software associated with eccentricity measurement is
a powerful tool for determining the need to perform relative
ENGLISH
rotation between the rim and tyre in order to reduce the eccentricity of the wheel down to acceptable limits. The principle
adopted is based on the consideration that a rim with acceptable
tolerance, mounted with an acceptable tyre, can statistically
generate a total eccentricity which is not acceptable but can
be improved by matching.
Generally speaking, rim measurement is not necessary,
accurate or useful because:
▪ To measure the rim it is necessary to remove the tyre.
There can by coarse errors on the outside (e.g. aluminium wheels!)
▪ The two rim sides can be eccentric in a very different
way . Therefore to which one to make reference? What
is the effect on the tyre mounted?
▪ T o improve the eccentricity of a wheel, the rim should be
eccentric, to compensate the tyre. And viceversa.
▪ If after a rotation by 180° of a wheel, the value is still
out-of-tolerance, either the tyre or rim are too eccentric:
One of the two must be replaced!

Use and maintenance manual Rev. 09-2013
5.10.2 Presetting of tolerance on the
machine
There is no general rule concerning acceptability of an eccen-
tricity value . As a rst approximation we consider it correct
to use a threshold of 1 to 1.5 mm. The E/ECE/324 standard
prescribes 1.5 mm as max. eccentricity of a rebuilt tyre.
5.10.3 Value of static unbalance, correlated
with eccentricity
Clear indication is given in the Measurement screen of both
the value and position of the static unbalance as well as the
eccentricity. In fact, it is interesting to check the correlations
of the two values, above all of the two positions. When the
two positions have a similar angle (± 30° one from the other),
there is a clear sign that an eccentricity is present which
can be compensated by matching.
5.10.4 Value of unbalance corresponding to
eccentricity
For user’s reference, the centrifugal force is calculated corresponding to a certain speed, compared to the force generated
by the eccentricity present on the tyre (calculated with an
approximate average elastic constant).
The maximum limit of the rst harmonic can be set (
FIRST HARMONIC LIMIT ). When this limit is exceeded,
the wheel balancer displays the red symbol above the
button to indicate an eccentricity condition that needs to be
corrected. Press

5.11 WHEEL ECCENTRICITY
MEASUREMENTS
The external radial eccentricity measurement is taken automatically at the end of the unbalance measurement without
having to perform specic procedures; remember to position
the sonar sensors in front of the surface to be measured
before performing a spin.
The much enlarged gures show the outer tyre surface and
axis of wheel rotation.

Fig. A - shows measurement of the total Peak-to-Peak eccen-
tricity dened as maximum radial deviation of the tyre surface.
Fig. B - shows measurement of the eccentricity of the 1st
harmonic, i.e. the eccentricity of that circle which “recopies”
the tyre shape, by averaging the local deviations of the tyre
from the round shape.
GRAPH 1 (yellow): shows the real peak-to-peak eccentricity .
GRAPH 2 (red): shows the first harmonic eccentricity.
An almost straight line graph indicates a wheel in perfect
condition.

7.8.2 External plane correction method
If correcting with adhesive weights, the unbalance is considered
within tolerance when the recalculated external plane weight
(clip-on weights) is lower than the tolerance set.
Additional windows appear on the screen always displaying
the residual external plane value (clip-on weight):
7.9 STATIC ALWAYS ENABLED
Simultaneous display of the selected correction plane unbalance as well as STA TIC unbalance can be enabled/disabled.
The static screen can be selected at any time by pressing

7.7.2 Unbalance display pitch
This represents the display pitch of the unbalance and varies
according to the unit of measurement selected. The selection
“5 g” (1/4 oz) enables display of the correction values on both
sides such as to bring the static unbalance to 0 (theoretical). It
is recommended to preset this function as standard use of the
machine as it improves the balancing quality. The computer
makes a complex calculation which allows cancelling the
residual static unbalance by varying the value and position of
the counterweights xed in steps of 5 grams (1/4 oz).
7.7.3 Tolerance
This is the unbalance threshold below which the word “OK”
instead of the unbalance value appears on the screen at the
end of the spin.
7.8 CORRECTION METHOD

10.1 DISPOSING OF THE BALANCER
The balancer must be disposed of after dismounting the
various parts.
For disposal operations, as well as wearing the Personal
Protective Equipment indicated in the INSTALLATION
MANUAL, refer to the instructions and diagrams in this
manual. If necessary, request specific information from
the manufacturer.
Once you have removed the various parts and components, separate them into the different types of materials
according to the differentiated waste disposal regulations
in force in the country where the machine is dismantled.
If the various components must be stored before being
taken to the dump, make sure to keep them in a safe place
protected from atmospheric agents in order to prevent
them from contaminating the ground and the water table.
The various parts can be identified using the drawings and
diagrams in the machine technical file which is archived
by the Manufacturer to which a request can be made.
For off-the-shelf parts, the technical manuals or the supplier's
original documents can be provided if the Manufacturer
deems this to be useful.
If not supplied, this documentation is also included in the
machine Technical File, archived by the Manufacturer, as
regards by Ministerial Decree 98/37/EC.
In this case, contact the Technical Service to identify the
required piece.
If the required pieces are not in any position or they can-
not be identified, contact the Technical Service, specifying the type of machine, its serial number and year of
construction.
