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 modiﬁed except for those modiﬁcations 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 ﬂapping 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.

- For TFT monitors, see the speciﬁc instructions attached.

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 ﬂying out in any direction except towards the ﬂoor.

- 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 certiﬁcate (option).

2 - Handling and hoisting

N.B.: DO NOT HOIST THE WHEEL BALANCER USING DIFFERENT GRIPS.

I 0463 - 5

3 - Commissioning

3.1 - Anchoring

The machine can be operated on any ﬂat non-resilient ﬂoor. Make sure that the machine rests solely on the three support points provided (ﬁg. 2a). If possible, it is advisable to anchor to the ﬂoor using relative mounting feet (see ﬁg. 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 ﬁtting is located at the back of the machine. A pressure of at least 7 kg/cm

(approx.

0.7 MPa or 7 BAR or 100 PSI) is required for correction operation of the release device.

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 ﬂanges can be mounted once the terminal part is removed (also see enclosed brochures) N.B. : CAREFULLY CLEAN THE COUPLING SURFACES BEFORE PERFORMING ANY OPERATION.

DISMOUNTING THREADED END PIECE

a) Back-off screw B and remove threaded end-piece A. b) Fit the new adapter.

Cone

- 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.

Spring

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 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, 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 other cone as a spacer to obtain spring thrust.

I 0463 - 9

4 - Controls and components

4.1 - Brake pedal

This pedal allows the operator to hold the wheel when ﬁtting the counterweights.

must not be actuated during the mea

suring cycle.

4.2 - Pneumatic locking pedal (SE Version)

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 speciﬁc 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 ﬁrst switch on, check the date and time (see

CLOCK SET-UP), adjusting

them if necessary.

4.7 - Printer (option)

Used to print useful information for the vehicle, residual imbalance and eccentricity for the balanced tyre.

4.8 - Keyboard

N.B. - Press the buttons with the ﬁngers only: never use the counterweight pincers or other pointed

objects.

- When the beep signal is enabled (see section

ACOUSTIC SIGNAL), pressing of any push button is

accompanied by a “beep”.

5 - Indications and use of the wheel balancer

The monitor shows several information and suggests various alternative ways of use to the operator. This is through various “screens”.

5.1 - Initial screen

Buttons enabled

: main functions screen (see

MENU ACCESS DIAGRAM)

selecting static correction

: balancing spin (see

RESULT OF MEASUREMENT)

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.

5.1.1 - Screen-save screen N.B.: Name of the wheel balancer’s owner. Can be preset via the monitor.
