3 - COMMISSIONING
3.1 - ANCHORING
The machine can be operated on any fl at non-resilient fl oor.
Make sure that the machine rests solely on the three support points provided (fi g. 2a).
It is advisable to secure the system to the ground using the specifi c 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 fi 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.
- Rotary block wheel retainer which, in the event of accidental pressing of the pneumatic locking
pedal during the balancing cycle, avoids risk of the wheel slipping from the adapter.
- 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 adapters can be mounted:

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 specifi c 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 GAUGE (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” in diameter.

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.

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 refi tted 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 (For example, see our models L36, L38/2).
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 fi 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.
8.2 - SPINDLE ADAPTER END PIECE SE
- Keep the inner felt ring constantly lubricated.
NONE OF THE OTHER MACHINE PARTS REQUIRE MAINTENANCE.
