1.1 - General safety recommendations
- The balancing machine should only be used by duly authorized and trained personnel.
- The balancing machine should not be used for purposes other than those described in the instruction
manual.
- Under no way should the balancing machine be modied except for those modications made explicitly by
the manufacturer.
- Never remove the safety devices. Any work on the machine should only be carried out by duly authorized
specialist personnel.
- Do not use strong jets of compressed air for cleaning.
- Use alcohol to clean plastic panels or shelves (AVOID LIQUIDS CONTAINING SOLVENTS).
- Before starting the wheel balancing cycle, make sure that the wheel is securely locked on the adapter.
- The machine operator should not wear clothes with apping edges. Make sure that unauthorized personnel
do not approach the balancing machine during the work cycle.
- Avoid placing counterweights or other objects in the base which could impair the correct operation of the
balancing machine.
1.1.1 - Standard safety devices
- STOP push button for stopping the wheel under emergency conditions.
- The safety guard of high impact plastic is with shape and size designed to prevent risk of counterweights
from ying out in any direction except towards the oor.
- A microswitch prevents starting the machine if the guard is not lowered and stops the wheel whenever the
guard is raised.
1.2 - Field of application

3.1 - Anchoring
The machine can be operated on any at non-resilient oor.
Make sure that the machine rests solely on the three support points provided (g. 2a).
It is advisable to secure the system to the ground using the specic feet (see Figure 2a) in the event of continual use with wheels weighing over 35 Kg.
3.2 - Electrical connection
The machine is supplied with a single phase mains cable plus earth (ground).
The supply voltage (and mains frequency) is given on the machine nameplate. It may NOT be changed.
Connection to the mains should always be made by expert personnel.
The machine should not be started up without proper earth (ground) connection.
Connection to the mains should be through a slow acting safety switch rated at 4A (230V) or 10A (115V).
3.3 - Pneumatic connection (versions SE)
For operation of the spindle with pneumatic locking (costant thrust air spring) connect the balancing to the compressed air main. The connection tting is located at the back of the machine. At least 7 Kg/cm2 (~ 0.7 MPa; ~ 7 BAR; ~
100 PSI) pressure is needed for correct operation of the release device.
3.4 - Extra safety devices (version SE)
- Wheel always locked even when there is pressure failure during the balancing cycle.
- Always actuate the unlocking control pedal with the machine stationary in order to avoid stress and
abnormal wear on the adapter.
3.5 - Adapter mounting
The balancing machine is supplied complete with cone adapter for fastening wheels with central bore. Other optional
anges can be mounted once the terminal part is removed (also see enclosed brochures).
N.B. Carefully clean the coupling surfaces before performing any operation

4.3 - Automatic distance and diameter gauge
This gauge allows measurement of the distance of the wheel from the machine and the wheel diameter at the point of
application of the counterweight.
It also allows correct positioning of the counterweights on the inside by using the specic function which allows reading the position used for the measurement within the rim.
The gauge can only be used with the counterweight pincers mounted.
4.4 - Automatic width (optional)
Width gauging is through a SONAR device which measures the distance of the wheel without mechanical contact,
merely by closing the guard and each time a valid measurement has been made with gauge DISTANCE AND
DIAMETER GAUGE.
4.5 - Automatic wheel positioning
At the end of the spin, the wheel is positioned according to the unbalance on the outside or else according to the
static unbalance (when selected).
Precision is ± 20° for wheels up to 25 kg. in weight. Positioning is automatically disenabled for wheels of less than 13”

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 signicantly from the rim).
This function can be enabled/disenabled by pressing push button prior to the measurement, which is then
performed by closing the guard; once completely closed and if “automatic START on guard closure” is enabled, the
launch will be made for unbalance measurement. If automatic START is disenabled, once the guard is closed the
display will show the width value measured.
This setting is also valid for the following correction modes:
The STATIC mode is required for motorcycle wheels or when it is not possible to
place the counterweights on the two sides of the rim.
Balancing of light alloy rims with application of adhesive weights on the shoulders of the
rims. The position of the weights is xed from the edges of the rim to the inside of the rim.
Combined balancing: adhesive weight on the outside and clip-on weight on the inside. The
position of the outside weight is xed from the outside edge of the rim to the inside of the
rim.
Combined balancing: adhesive weight on the inside and clip-on weight on the outside.
The position of the inside weight is xed from the edge of the rim to the inside of the rim.
b) Balancing of alloy rims with hidden application of the outside adhesive weight.

Press after new setting of the measurement value again.
5.6 - Split function (hidden weight)
The SPLIT function is used to position the adhesive weights behind the wheel spokes so that they are not visible. This
function should be used only in the case of static unbalance or where the hidden adhesive weight is to be applied on the
outside. Input the wheel dimensions and do a spin.
Start the SPLIT function as follows:
14
Example of display prior to SPLIT function
- Place the wheel in the outside unbalance correction
position.
- Set one of the top spokes (preferably the one to the left
of the unbalance) to 12 o’clock.

RETURN TO MEASUREMENT SCREEN.
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.

5.9 - Eccentricty measurement (option)
The gures are signicantly enlarged to highlight the external surface of the tyre and the wheel rotation axis.
Fig. A highlights the total Peak-Peak eccentricity measurement, dened as the maximum radial offset of the surface
of the tyre.
Fig. B highlights the 1st harmonic eccentricity measurement, i.e. the eccentricity of the rim “reecting” the shape
of the tyre, to calculate the averages values of local offset
of the tyre from roundness.
It is evident that the P-P measurement is
normally higher than the 1st harmonic
measurement. Tyre manufacturers usually provide two
different tolerances for the two types of eccentricity.
At the end of a balancing spin, eccentricity measurement of the tyre can be performed automatically using the
SONAR sensor placed on the guard. To enable measurement at the end of every spin, see the section MENU
FUNCTION CONTROL.

6.2 - Self-calibration
For machine self-calibration proceed as follows:
- Fit a medium-sized metal wheel on the shaft. Example: 6” x 14” (± 1”)
- Preset the exact dimensions of the wheel mounted.
CAUTION!! Presetting of incorrect dimensions would mean that the machine is not correctly calibrated,
therefore all subsequent measurements will be incorrect until a new self-calibration is performed
with the correct dimensions!
- Perform a spin under normal conditions.
- Add a 100 g. sample weight (3.5 oz) on the outside in any angular position.
- Shift the sample weight from the outside to the inside keeping the same
angular position.
- Shift the sample weight to the 12 o’clock position.

2. Repeat the SPLIT function increasing the distance between the
spokes.
1. Position the eccentricity measurement sonar correctly before
performing the measurement.
2. Check eccentricity sonar connections.
3. Check the power supplies on the power card.
4. Replace the eccentricity measurement sonar.
5. Make sure that the wheel does not halt before completing at least
4/5 revolutions after the first braking impulse.
6. Verify belt tautness.
7. Replace the computer board.
1. Position the eccentricity measurement sonar correctly before
performing the measurement.
2. Make sure that the wheel does not halt before completing at least
4/5 revolutions after the rst braking impulse.
3. Verify belt tautness.
4. Mount a wheel of medium dimensions (14”x5 ”) and perform an
eccentricity measurement . If in these conditions error 55 no longer
occurs, this means that the wheel inertia causing the problem is
such as to half the wheel before having acquired the minimum
number of values necessary for reliable eccentricity measurement.
7.1 - Inconsistent unbalance readings
Sometimes after balancing a wheel and removing it from the balancing machine, it is found that, upon 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 or studs.
If, after balancing, the wheel is found to be still out-of-balance when retted on the vehicle, this could be due to
the unbalance 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.
8 - Routine maintenance
Switch off the machine from the mains before carrying out any operation.
8.1 - To replace the fuses
The power supply board, accessible from the rear by removing the rear cover, is tted with safety fuses (see
Exploded Drawings). If fuses require replacement, use ones of the same current rating.
If the fault persists, contact the Technical Service Department.
NONE OF THE OTHER MACHINE PARTS REQUIRE MAINTENANCE.
