1.1 - General safety regulations
The wheel balancer may only be used by duly authorized and trained personnel.
The wheel balancer must not be used for purposes other than those described in the instruction manual.
The wheel balancer may not be modifi ed in any way, except for modifi cations made explicitly by the
manufacturer.
Do not remove the safety devices. Any work on the machine must be carried out by specialised personnel
only.
Avoid using strong jets of compressed air for cleaning.
Use alcohol to clean plastic panels or shelves (AVOID LIQUIDS CONTAINING SOLVENTS).
Before starting the balancing cycle, make sure that the wheel is securely locked on the fl ange.
The machine operator must not wear clothes with fl apping parts. Do not allow unauthorized personnel to
approach the wheel balancer when the cycle is running.
Avoid placing objects in the bases which could compromiseproper functioning of the wheel balancer.
1.1.1 - Standard safety devices
Two-handed control to start the balancing spin. During the spin, the operator is obliged to stay in a lateral
position, away from the wheel.
Slow rotation speed.
1.2 - Field of application
The wheel balancer has been designed for balancing motorcycle wheels (max. wheel weight = 30 kg).
It can be operated in a temperature range of 0° to + 45° C.
The following functions are provided: Unbalance optimisation; Autodiagnostics; Autocalibration.

▪
▪
3.1 - Anchoring
The machine can operate on any fl at non resilient fl oor. Make sure that the machine rests solely on the three support
points provided (
3.2 - Electrical connection
(A) The machine is supplied with a single- phase mains cable plus earth (ground).
The power supply voltage (and mains frequency) is indicated on the machine identifi cation plate and cannot be
changed. Connection to the mains must always be made by expert personnel. The machine must not be set up
without proper earthing. Connection to the mains must be made with a slow-acting safety switch calibrated to 3A
(230V) or 8A (115V) . See enclosed diagram.
3.3 - Fitting the wheel fi xture shaft (see attached prospectus)
The balancing machine's main advantage is its fi xed shaft tool. This means that when the wheel is fi tted on the tool, it
is free to turn on its own bearings, exactly reproducing the conditions of use when it is fi tted on the motor bike.
Balancing is not affected by inaccuracies in the wheel-fl ange-shaft coupling typical of traditional rotating shaft balan
cing machines. This means that you can achieve the best possible accuracy.
Use the AF12 or AF15 tools with cones and axial blockage rings for wheels with traditional fi xture
(through- journal).
Use the rotating AGF tool for wheels with outboard fl anged fi xture (BMW, Honda).(See specfi c brochure for correct
assembly).
Push the chosen tool well home into the balancing machine’s hollow shaft and block it in position by tightening the
screws accessible from the baseplate hole.
Fig. 2a).
NOTE ON AGF TOOL: Remove it from the balancer after use to avoid permanent deformation of
brush bristles.
3.4 - Fitting the wheel
The AF12 and AF15 fi xed shaft tools enable you to fi t wheels with a maximum hole of 35 mm on their own bearings.
Do not overtighten the threaded ring, as this would put excessive axial load on the bearings. When you fi t the wheel,
you will notice that the brush adapts automatically (radially) to the shape of the wheel hub. During balancing operations, the brush will turn together with the wheel and transmit the motion to the balancing machine’s built-in position
transducer. If you use the special AGF tool, the rotating movement will be transmitted to the brush by the rotating part
of the tool.

5.3 - Wheel balancing
5.3.1 - Measuring unbalance
▪ Move the front lever to the right bringing the pulley into contact with the tyre and press the run button on the side
holding the lever pushed in order to spin the wheel. If used without motor, spin the wheel by hand respecting the
correct direction of rotation (anticlockwise).
▪ Release the lever and the START key when the displays go off, the machine will then start making measurements.
▪ When the displays show the measurement values, brake the wheel by re-establishing contact with the pulley, which
is braked when the motor is off. Instruments 1 and 2 will keep the dynamic unbalance values in their memories.
When balancing for static, the value is shown on display 1.
▪ LEDs on displays 3 and 4 will indicate the correction position. If all the LEDs are alight, this means that the correc
tion weight should be applied to the vertical apex. They mean the same when balancing for static.
▪ For small diameter wheels (scooters), launch always the wheel by hand in anticlockwise direction (see arrow).
Measurement always begins when the displays go off.
I 0685 - 9
GB
5.3.2 - Correcting the unbalance
STATIC: Apply two identical correction weights at the highest point of the wheel, one on the inside shoulder and
the other on the outside shoulder of the rim. Each weight is half the value indicated by the display.
If you make the correction with lead wire, springs or clamps applied to the spokes, divide it onto one, tow
or more spokes, according to the size of the unbalance.
DYNAMIC: Apply the adhesive weights to the shoulders of the wheel rim in the positions indicated by the display for
each of the sides.

Correction of inner side Correction of outer side
Digital readouts with LED ‘s 3 - 4 lit up indicate the correct angular wheel position to mount the counterweights (12
o’clock position).
In the event of unbalance less than the selected threshold value
0 is displayed in place of the unbalance
value , with
N.B.: In rare cases and in temperature conditions near 0°, the wheel balancer automatically activates a
special measuring cycle involving two successive measurements.
During the unbalance measurement, the word “START” reappears to indicate to the user to bring
the wheel back up to speed. The accuracy of the unbalance values and the reliability of the wheel
balancer remain unchanged.

▪ Press , without repeating the spin.

5.5 - Unbalance optimisation
- This function serves to reduce the amount of weight to be added in order to balance the wheel
- It is suitable for static unbalance greater than 30 g.
- It improves the residual eccentricity of the tyre.

▪ Spin the wheel
▪ Stop the wheel
▪ RH display: percentage reduction

This program is designed to improve the quality of balancing without any mental effort or waste of time by the operator. In fact, using the normal weights available on the market (pitch of 5 in every 5 g) and applying the two counterweights which a conventional wheel balancer rounds to the nearest value, a residual static unbalance of up to 4 g
may result. The damage of such approximation is emphasized by the fact that static unbalance is the cause of most
disturbances on motorcycle. This new function automatically indicates the optimum entity of the weights to apply by
approximating them in an “intelligent” way according to their position in order to minimize residual static unbalance.

6 - SET UP
6.1 - Autodiagnostics
performs tests useful for maintenance staff.
6.2 - Autocalibration
For autocalibration proceed as follows:
▪ Fit a wheel of average dimensions even one that is unbalanced.
▪ Set the exact dimensions of the wheel mounted.
CAUTION !! Setting incorrect dimensions will result in the machine not being properly calibrated
and hence all the subsequent measurements will be incorrect until a new autocali
bration is performed with the correct dimensions!!
- Perform a spin under normal conditions
- Stop the wheel
- Add a 30 g. sample weight (1.00 oz) on the outside in any angular position.
- Perform a spin
- Stop the wheel
- Shift the sample weight from the outside to the inside keeping the same angular
position.
- Perform a spin
- Stop the wheel
- Turn the wheel until the sample weight is in the 12 o’clock position.
