1- General
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 modifi ed except for those modifi cations 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 fl 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 fl ying out in any direction except towards the fl 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
The machine is designed for balancing car or motorcycle wheels weighing less than 75 kg. It can be operated within a
temperature range of 0° to + 45°C.
It can measure the geometric radial run-out of the wheels (optional)
It can print a balancing certifi cate (option).

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).
If possible, it is advisable to anchor to the fl oor using relative mounting feet (see fi g. 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 amp (230V) or 10 amp (115V) .
3.3 - Pneumatic connection (SE Version)
For operation of the spindle with pneumatic locking (constant thrust air spring) connect the balancing machine to the
compressed air main. The connection fi tting is located at the back of the machine. A pressure of at least 7 kg/cm
0.7 MPa or 7 BAR or 100 PSI) is required for correction operation of the release device.

(approx.
3.4- Extra safety devices (SE Version)
- 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
fl 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.

- Quando possibile, centrare le ruote con cono dall'interno (vedi disegno).
- Evitare di usare il manicotto RL con cerchi di ferro.
- Whenever possible, centre the wheels with the cone from the inside (see the drawing).
- Avoid using the RL sleeve with metal rims.
- Lorsque c’est possible, centrer les roues avec le cône de l’intérieur (voir dessin).
- Eviter d’utiliser le manchon RL avec les jantes en fer.
- Wenn möglich, die Räder mit Konus von Innen heraus zentrieren (siehe Zeichnung).
- Bei Eisenfelgen die Verwendung der Muffe RL vermeiden.
- Siempre que sea posible, centrar las ruedas con cono desde dentro (véase dibujo).
- Evitar usar el manguito RL con llantas de hierro.
- Quando possível, centre as rodas com cone pelo lado de dentro (ver fi gura).
- Evite utilizar a luva RL com jantes de ferro.

3.6 - Guard mounting and adjustment
a) Fasten the components to the base as illustrated in specifi c exploded view.
b) The position of the wheel guard when closed can be adjusted with relative screw accessible at the back. Correct
position is the one which keeps the tube exactly horizontal with wheel guard closed.
c) Check that the microswitch is held down when the guard is closed.
d) Adjust the angular position of microswitch control.
3.7 - Spacer WD
When balancing very wide wheels (9”), there is not enough space to turn the distance gauge. To withdraw the wheel
from the machine side, fi t spacer WD on the adapter body and secure it with the standard issue nuts. When centring
the wheel with the cone on the inside, fi t the other cone as a spacer to obtain spring thrust.

4.2 - Pneumatic locking pedal (SE Version)
This pedal allows the operator to hold the
wheel when fi tting the counterweights. It
must not be actuated during the measuring cycle.
6
This pedal allows releasing the device
fastening the wheel on the adapter. Do not
actuate this pedal during the machine
cycle and/or when adapters other than the
standard cone adapter are mounted.
The pedal has two stable positions:
top, wheel unclamped; bottom, wheel
clamped.
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 rim by using the
specifi c function (see
the position used for the measurement within the rim (For calibration, see the corresponding section).
The gauge can only be used with the counterweight pincers mounted.
INDICATION OF EXACT CORRECTION WEIGHT POSITION ) which allows reading, on the monitor,
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
AND DIAMETER GAUGE
.
AUTOMATIC DISTANCE
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).
Accuracy is ± 20 degrees.
4.6 - Clock control
The wheel balancer is provided with a clock having a back-up of about one month with the machine switched off. If the
machine remains off for a long period, at the fi rst switch on, check the date and time (see
them if necessary.

Dimensions gauge: when extracted, the Dimensions screen is selected (see PRESETTING OF WHEEL
DIMENSIONS).
If the machine remains on the initial screen for a certain amount of time without being used, the system is
automatically switched to a screen-save. Striking of any key, movement of the wheel of distance
+ diameter gauge will cause automatic switching from the screen-save menu to the initial screen.
