3.1 - ELECTRICAL CONNECTION ►

T
BE MADE BETWEEN PHASE AND NEUTRAL, AND NEVER, UNDERANY CIRCUMSTANCES, BETWEEN PHASE AND EARTH (GROUND).
E
FFICIENT EARTHING (GROUNDING) IS ESSENTIAL FOR CORRECT MACHINE OPERATION. THE MANUFACTURER DECLINES
RESPONSIBILITY AND WARRANTY IN THE EVENT OF INCORRECT CONNECTION.
ALL
Before connecting the machine to the mains through relative cable, check that the mains voltage matches the one
shown on the nameplate at the back of the balancing machine. Rating of the electrical connection should be on the
basis of the machine electrical power consumption (see nameplate).
The machine mains supply cable should be fi tted with a plug conforming to current regulations. ▪
It is recommended to provide the machine with its own electrical connection through a slow acting safety switch ▪
rated at 4 A (230 V) or 8 A (115 V).
When connection is made directly to the main control panel without using any plug, it is advisable to padlock the ▪
main switch of the balancing machine in order to limit its use to authorized personnel only.
3.2 - ADAPTER MOUNTING ►
The wheel balancer is supplied complete with cone ►
type adapter for fastening wheels with central bore.
The threaded terminal is fi tted according to the dra
wing; it can be removed to fi t optional adapters.
It can be removed to fi t optional adapters.
3. ► 3 - WHEEL MOUNTING
The wheels should be fastened with one of the numerous adapters manufactured by the manufacturer (see enclosed
brochures). Incorrect centering inevitably causes unbalance.
3.4 - WHEEL GUARD ASSEMBLY ► (option)
Fasten the components to the base as illustrated in the specifi c exploded drawing1.
The positions of these guards can be adjusted using the special screws accessed from inside the main support2.
With th3. e guard closed check that the microswitch prod has slipped into place on the ring; to this end, adjust the
angular position of the control ring if necessary.

5 - USE OF THE WHEEL BALANCER
5.1 - DATA SETTING ►
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 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
measured with the compass gauge provided.
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:
. The correct measurement is that which can be

5.2 - RESULT OF MEASUREMENT ►
Inside correction Outside correction
After performing a balancing spin, the amounts of unbalance are shown on the digital readouts.
Digital readouts with LED lit up indicate the correct angular wheel position to mount the counterweights (12 o’clock
on).
positi
If the unbalance is less than the threshold selected, 0 is displayed instead of the unbalance; with it is possible
to read the values below the threshold chosen.
Note : in the case of wheels with a diameter less than or equal to 13” and at temperature conditions near
0°, the wheel balancer automatically inserts a special measuring cycle composed of two
successive measurements. The accuracy of the unbalance values and the reliability of the wheel
balancer remain unchanged. This type of operation is reset each time the wheel balancer is started.
5.2.1 - STATIC UNBALANCE ►
It is selected by pressing and is shown on the central display. The position is indicated on the displays 3 and 4.

The normal balancing condition requires the correction weight to be applied at the top (12 o’clock) when the symbol
is displayed:
Apply the correction weight at the top (12 o’clock)
If OPPOSITE POSITION is enabled, the eventual application position for the bottom weight is also indicated next to

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.
ddxx
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.

7.1 - INCONSISTENT UNBALANCE READINGS ►
Sometimes after balancing a wheel and removing it from the balancing machine, it is found that, mounting it on the
machine again, the wheel is not balanced.
This does not depend on incorrect indication of the machine, but only on faulty mounting of the wheel on the adapter
i.e. in the two mountings the wheel has assumed a different position with respect to the balancing machine shaft centre
line. If the wheel has been mounted on the adapter with screws, it could be possible that the screws have not been
correctly tightened, i.e. crosswise one by one, or else (as often occurs) holes have been drilled on the wheel with too
wide tolerances. Small errors, up to 10 grams (0.4 oz) are to be considered normal in wheels locked by a cone; the error
is normally greater for wheels fastened with screws.
If, after balancing, the wheel is found to be still out-of-balance when refi tted on the vehicle, this could be due to unba-
lance of the car brake drum or very often due to the holes for the screws on the rim and drum sometimes drilled with
too wide tolerances.
In such case a readjustment could be advisable using the balancing machine with the wheel mounted on the car.
8 - ROUTINE MAINTENANCE (see exploded drawings) (for non specialized personnel only
Always disconnect the machine from the mains before carrying out any operation.
,
8.1 - TO REPLACE THE FUSES ►
Remove the weight holder shelf to gain access to the power supply board where the fuses are located. If fuses
require replacement, use ones of the same current rating. If the fault persists, contact Technical Service.
NONE OF THE OTHER MACHINE PARTS REQUIRE MAINTENANCE.
