2.1 PURPOSE
C72/2 EVO C72SE/2 EVO is used to balance the wheels
of cars, vans, 4-WD, motorcycles and scooters weighing
less than 75 Kg. It can be operated in the temperature
range of 0° to + 45°C.
The machine can operate only on fl at non resilient fl 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.
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.

ENGLISH
5.1 PRESETTING OF WHEEL DIMENSIONS
The balancing data is set by means of an “intelligent” automatic gauge; confi rmation of the measurement and the
position appear on the display. The round part of the gauge
must rest on the rim where the weight will be positioned.
a
The correct measurement is that which can be measured
with the compass gauge provided.
b
b) adhesive weights: make two successive measurements
on two correction planes inside the rim.
The balancing machine automatically interprets that the
correction will be made with adhesive weights and the
following appears:
For a different combination of the type or position of the
weights on the rim, use the button
.
b
While the gauge is moving the following appears:
when the measurement has been stored:
a) standard weights: when only one measurement is
made, the machine interprets the presence of a rim with
clip-on weight correction
The width value (b) must be set with the
buttons .
AUTOMATIC WIDTH (OPTION)
At the end of automatic distance and diameter measurement, if the LA sonar is present, the machine prepares
for acquisition of this value:
The LT script on the LH matrix display indicates that LIGHT
TRUCK wheel measurement is set (large dimension wheels
such as off-road, trucks or wheels which protrude signifi cantly
from the rim).
This function can be enabled/disenabled by pressing push
button
“beep” is heard. If “AUTOMATIC START” is enabled when
the guard is closed, the balancing machine performs a
cycle to measure the imbalance, otherwise the width value
just acquired is shown.

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.

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.
Obviously the P.P. measurement is normally greater than that
of the 1st harmonic. Tyre manufacturers normally supply two
different tolerances for the two eccentricities.
The radial eccentricity measurements is automatically carried
out after the unbalance measurement without having to go into
particular procedures. Remember to position the sonar sensor

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 mounting 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 (crisscross 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 refitted 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 identifies the most frequent malfunctions during the normal
work cycle.
These malfunctions are processed by the system and
shown on the display.
