4.1 FITTING THE WHEEL FIXTURE SHAFT
(SEE ATTACHED PROSPECTUS)
The balancing machine’s main advantage is its fixed shaft
tool. This means that when the wheel is fitted on the tool, it
is free to turn on its own bearings, exactly reproducing the
conditions of use when it is fitted on the motor bike.
Balancing is not affected by inaccuracies in the wheel-
flange-shaft coupling typical of traditional rotating shaft
balancingmachines.Thismeansthatyoucanachieve the
best possible accuracy. Use the AF12 or AF15 tools with
cones and axial blockage rings for wheels with traditional
fixture (through- journal).
UsetherotatingAGFtoolforwheelswithoutboardflanged
fixture (BMW, Honda).(See specfic brochure for correct
assembly).
Push the chosen tool well home into the balancing ma-
chine’s hollow shaft and block it in position by tightening
the screws accessible from the baseplate hole.
NOTE ON AGF TOOL
Removeitfromthebalancerafterusetoavoidpermanent
deformation of brush bristles.
4.2 FITTING THE WHEEL
TheAF12 andAF15 fixed shaft tools enable you to fit wheels
withamaximum hole of 35 mm ontheir own bearings. Donot
overtightenthethreadedring,asthiswouldputexcessiveaxial
load on the bearings. When you fit 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
balancingmachine’sbuilt-inpositiontransducer.Ifyouusethe
special AGF tool, the rotating movement will be transmitted
to the brush by the rotating part of the tool.

6.2 WHEEL BALANCING
6.2.1 Measuring unbalance
Move the front lever to the right bring▪ing the pulley into
contactwiththetyreandpresstherunbuttonontheside
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.
Whenthedisplaysshowthemeasurementvalues,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 correction weight should be applied to the vertical
apex. In static mode, both displays indicate the same
position (static unbalance).
Forsmall diameter wheels(scooters), launchalwaysthe▪wheel by hand in anticlockwise direction (see arrow).
Measurement always begins when the displays go off.
6.2.2 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 shoul
der 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
angularwheelpositiontomountthecounterweights(12o’clock
position). In the event of unbalance less than the selected
threshold value 0is displayed in place of the unbalance
value , with it is possible to read the values below the
selected threshold gr. by gr.

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.
6.3 RECALCULATING UNBALANCE

This program is designed to improve the quality of ba-
lancing without any mental effort or loss of time by the

mum entity of the weights to be applied by approximating
them in an “intelligent” way according to their position in
order to minimize residual static unbalance.

8. Diagnostics
8.1 INCONSISTENT UNBALANCE
READINGS
In some cases, when a wheel that has just been balanced
is repositioned on the balancer, the machine can detect
an unbalance.
Thisisnotamachineproblembutisduetofaultymounting
of the wheel on the flange. In other words, when mount-
ing the wheel after initial balancing, it has taken another
position with respect to the balancer shaft axis.
If the wheel has been mounted on the flange with screws,
the screws may not have been tightened correctly (criss-
cross sequence) or the tolerances of the holes drilled in
the wheel may be too large. Small errors, up to 10 grams
(4 oz), are to be considered normal in wheels locked with
the relative cone: The error is normally greater for wheels
locked with screws or studs.
If, after balancing, the wheel is still unbalanced when re-
fitted on the vehicle, this could be due to an unbalanced
brake drum or, very often, the tolerances of the holes
drilled in the rim and drum are too large. In this case,
balancing should be performed using a balancer with the
wheel mounted on the vehicle.
8.2 ALARM SIGNAL
The machine has a self-diagnostics cycle which identi-
fies the most frequent malfunctions during the normal
work cycle.
These malfunctions are processed by the system and
