2.1 PURPOSE
The C88 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
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 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.

5.8 “SPLIT” CONTROL (HIDDEN WEIGHT)
SPLIT is only possible in the event of static unbalance or
ALUS external side and is used to hide any adhesive weights
correcting unbalance behind the rim spokes.
ENGLISH
T o split the unbalance detected in two different positions,
proceed as follows :
1. Position static unbalance or ALUS external side in the
correction position :
5.9 CORRECTION MODE
After having performed automatic measurement of the
inner side, it is possible to place the correction weights as
required by pressing pushbuttons
INDICATION
In the event of automatic measurement of both sides, if
the difference between the inner and outer diameters is
greater than or equal to 2”, the system sets the inner side
spring weight.

3. Turn the wheel in the rotation direction indicated on the
unbalance display, brining the second spoke to the 12
o’clock position and press button .
Turn the wheel in direction of rotation.
Turn the wheel in reverse direction of
rotation.
4. At this point, two indications appear on screen for
positioning of the unbalance correction spokes.
5. Position the spokes indicated on screen in the 12
o’clock position and correct with the value displayed.
Any error in this procedure is clearly shown on screen.
Always follow the information provided by the wheel to
optimise correction.
To modify this presetting, press the

Choice with minimum static
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
rotation between the rim and tyre in order to reduce the eccen-
tricity 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?
To 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!
Example 1
Example 2

Tyre - 0.6 mm

The wheel is acceptable.

Tyre + 0.6 mm

Eccentricity of the wheel is excessive, due to an acceptable
rim or tyre but randomly placed in an “unfortunate” relative
position.
SOLUTION: Rotate the tyre on the rim by 180°
RESULT: wheel eccentricity 0.3 - 0.4 mm (in tolerance)

compensated by the rotation because
the rim is perfect!
SOLUTION: Rotate the tyre on the rim by 180°
RESULT: no improvement is obtained.

5.10.2 Presetting of tolerance on the
machine
There is no general rule concerning acceptability of an eccentricity value . As a fi rst approximation we consider it correct
ENGLISH
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 fi 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. To go to the eccentricity measurement manage-
ment frame, press the button

The innovative IC software has been designed to reduce
INDICATION
the amount of weight used to correct the
unbalance, leaving a residual unbalance on the wheel
within the set tolerances.
The tolerance used by the machine is obtained from a
tolerance of a reference wheel, modified in order to
make the vibration generated by the reference wheel
comparable with that in use.
This is obtained according to the coded theory
of the ISO standards.
In general, a wheel balanced using IC has a higher
residual unbalance than a wheel balanced at best using
the conventional method, but, although generating a
tolerable vibration from the vehicle, it has the
advantage of considerably reducing the counterweights

9.1 GENERAL
CAUTION
BEFORE PERFORMING ANY MAINTENANCE OPERATIONS, MAKE SURE
THE MACHINE HAS BEEN DISCONNECTED FROM THE MAINS POWER
SUPPLY. ALWA YS USE THE PERSONAL PROTECTIVE EQUIPMENT
INDICATED IN THE INSTALLATION MANUAL.
9.1.1 Introductory notes
This machine has been designed so as not to require routine maintenance, apart from accurate periodic cleaning.
It is important to keep the machine perfectly clean in order to prevent dust or impurities from compromising the
operation of the balancer.
WARNING
THE PEOPLE RESPONSIBLE FOR CLEANING THE AREA WHERE THE
MACHINE IS INSTALLED MUST WEAR PERSONAL PROTECTIVE EQUIPMENT
IN ORDER TO WORK IN SAFETY AND ACCORDING TO THE CURRENT
OCCUPATIONAL HEATH AND SAFETY REGULATIONS.
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 attention.
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 during 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.
9.1.3 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.
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.
9.1.2 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 Equipment indicated in the Installation Manual. During activities, unauthorised people may not access the equipment
and WORK IN PROGRESS signs will be erected in the
