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 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
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)

NB: DO NOT HOIST THE MACHINE USING DIFFERENT GRIPS.
3 - Commissioning
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

- 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.

3.6 - Guard mounting and adjustment
a) Fasten the components to the base as illustrated in specific exploded view.
b) The position of the wheel guard when closed can be adjusted with relative screw accessible at the back. Correct
position is shown in Fig. 1.
c) With the guard closed check that the microswitch prod has slipped into place on the ring.
d) Appropriately adjust the angular position of the control ring.
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, fit spacer WD on the adapter body and secure it with the standard issue nuts. When centring
the wheel with the cone on the inside, fit the spacer DC to obtain spring thrust.

This pedal allows releasing the device
fastening the wheel on the adapter.
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.

GB
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”
in diameter.
