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 65 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)

2 - HANDLING AND HOISTING
N.B.: DO NOT HOIST THE WHEEL BALANCER USING DIFFERENT GRIPS

GB

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).
If possible, it is advisable to anchor to the oor using relative mounting feet (see 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 (Versions SE)
For operation of the spindle with pneumatic locking (constant thrust air spring) connect the balancing
machine to the compressed air main. The connection tting is located at the back of the machine.
A pressure of at least 7 kg/cm2 (approx. 0.7 MPa or 7 BAR or 100 PSI) is required for correction
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 - CONTROLS AND COMPONENTS
4.1 - BRAKE PEDAL
Fig. 5
4.2 - PNEUMATIC LOCKING PEDAL (Version SE)
Fig. 6
This pedal allows the operator to hold the
wheel when tting the counterweights.
It must not be actuated during the
measuring cycle.
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 specic function (see Indication of exact correction weight position ) which
allows reading, on the monitor, 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.
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
AUTOMATIC 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).
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 rst switch on, check the date and time
(see Clock set-up), adjusting them if necessary.
