Machine description
2.1 PURPOSE
Megaspin 800_2/800P_2 is used to balance the wheels
of cars, vans, 4-WD, motorcycles and scooters weighing
less than 75 Kg. It can be operated in the temperature
range of 0° to + 45°C.
The machine can operate only on flat non resilient floor.
To lift the machine, lever only on the base where the 3
support points are located. never, under any circustance,
apply force to other points such as the spindle, head, or
accessory shelf. It functions properly without having to
fasten it to the floor with wheels weighing up to 35 kg; for
heavier wheels, fasten it at the points indicated.
Thanks to the new and exclusive VDD (Virtual Direct Drive)
system, reliable unbalance measurements can be made
in a short time, almost half the time of the cycle used with
respect to other balancers in this range.
The main features include:

THE OPERATOR, GIVEN THE PRESENCE OF VOLTAGE ON THE
EQUIPMENT. THE PERSONAL PROTECTIVE EQUIPMENT DESCRIBED
IN THE INSTALLATION MANUAL MUST BE WORN AND WORK
MUST BE DONE WITH DUE CARE AND ATTENTION.
OPERATIONS MAY ONLY BE PERFORMED BY A
SPECIALISED TECHNICIAN.
Before powering the machine, carry out the following
checks:
check that the balancing machine touches the floor1.
at the three support points;
2. make sure that all the parts of the balancer are cor
rectly connected and fixed;
3. makesurethattheparameters(voltageandfrequency)
ofthemainspowersupplyarecompatiblewiththose
indicated on the rating plate of the balancer;
4. make sure the power cable is correctly connected;
5. make sure the machine shaft and flange hole are
clean.
CAUTION
ANY TRACES OF DIRT MAY AFFECT BALANCING ACCURACY.
6. Positionthewheelontheterminalwiththeinnerpart
facing the balancer;
7. Firmly attach the wheel to the balancer shaft using
the lock nut. In the pneumatic version, use the spe
cific collar provided. For operation of the spindle
with pneumatic locking (constant thrust air spring)
connect the wheel balancer to the compressed air
mains. The connection fitting is located at the back
of the machine. At least 8 Kg/cm2(~ 0.8 MPa; ~
8 BAR; ~ 115 PSI) pressure is needed for cor
rect operation of the release device.
8. In the normal version, the pedal controls a mechani
cal brake which facilitates locking the locking ring
and positioning the wheel for correction.
In the pneumatic version, it allows fastening/relea
sing the wheel on the adapter using the collar. The
pedal has two stable positions: upper position for
unlocking; lower position for locking the wheel.
9. The wheel is automatically locked when it reaches
the correct angular position for application of the
weight on the inside and outside by turning it slowly
by hand. To release the wheel, turn it forcefully to
move it from the correct correction position. If the
unbalance is within tolerance, the wheel is locked
automatically.
10.To switch on the balancer press the switch on the
left-hand side of the machine.

5.8.1 MINISTAT - Automatic minimization of
static unbalance
This function can be selected from the Setup screen. It serves
for optimizing the residual unbalance by correcting a wheel
with standard counterweights in 5 gram (1/4 oz.) steps.
Thanks to this particular function, the position and best cor-
rection value are calculated in order to minimise static
unbalance: the main cause of the vibrations which can
be felt inside the car.

6.2 UNBALANCE OPTIMIZATION
The symbol is displayed automatically for static unba-
lance higher than 30 grammes (1.1oz).
The program allows total wheel unbalance to be reduced
by compensating, when possible, tyre and rim unbalance
values. It requires two runs, rotating the tyre on the rim on
the second run.

6.3 WHEEL BALANCER MACHINE SELF
CALIBRATION
For machine calibration, proceed as follows:
Fit a wheel with steel rim of average dimensions, such▪
as: 6” x 14” (± 1”).
Preset the wheel dimensions with▪GREAT CARE.
CAUTION
SETTING INCORRECT DIMENSIONS WILL RESULT IN THE MACHINE NOT
BEING PROPERLY CALIBRATED AND HENCE ALL THE SUBSEQUENT
MEASUREMENTS WILL BE INCORRECT UNTIL ANEW SELFCALIBRATION
IS PERFORMED WITH THE CORRECT DIMENSIONS!!
SELF CALIBRATION MUST ONLY BE PERFORMED BY SPECIALIST
PERSONNEL AND IF ABSOLUTELY NECESSARY.
Follow the on-screen instructions.▪
6.4 STATISTICS
DAILY N° OF RUNS:
Indicates the number of runs performed as from switching
on the machine.
Such parameter is automatically reset after switching the
machine off.
TOTAL N° OF RUNS:
Indicates the number of runs starting from the date indica-
ted in square brackets.
This parameter remains memorized even when the machi-
ne is switched off.
DAILY WEIGHT SAVED
Indicates the weight saved when using the WEIGHT LESS
instead of the standard correction method from the moment
the wheel balancer is turned on. This parameter is automa-
tically reset after turning off the machine.
TOTAL WEIGHT SAVED
Indicates the weight saved when using the WEIGHT LESS
instead of the standard correction method from the date
indicated in square brackets. This parameter remains me-
morized even when the machine is switched off.

6.5 RUN-OUT - ECCENTRICITY
MEASUREMENT (OPTION)
The much enlarged figures show the outer tyre surface and
axis of wheel rotation.
Figure A shows measurement of the total Peak-to-Peak
eccentricity defined as maximum radial deviation of the tyre
surface.
Figure Bshows measurement of the eccentricity of the 1st
harmonic, i.e. the eccentricity of the circle which “copies”
the tyre shape, by averaging the local tyre deviations from
the round shape.
Obviously the P.P. measurement is normally greater than
that of the 1st harmonic. Tyre manufacturers normally
supply two different tolerances for these two eccentricities.
At the end of the balancing run, it is automatically possible
to measure tyre eccentricity through the SONAR sensor
installed on the machine. The sensor should be positioned
by hand in front of the tyre tread. (max. wheel Ø: 1000
mm).
INDICATION
For 1st harmonic the max. deviation usually should not
exceed 1,2 mm. The symbol above button 4 changes to
red as soon as this value is too high.
GRAPH 1: indicates the effective Peak-Peak eccentricity
GRAPH 2: indicates the first harmonic eccentricity. For a
wheel in excellent condition, this graph should approach a
straight line.
When the wheel is moved, the cursor on the screen indica-
tes the actual value, with the phase referred to the correc-
tion point.

7. Setup
The Setup screen provides the user with many possibili-
ties required for presetting the machine in relation to his
own requirements. Such settings remain unaltered even
when the machine is switched off. The following buttons
are enabled:
: return to previous window;
:return to measurement screen;
from to : for parameter selection.
7.1 LANGUAGE
This function allows selection of the language to be used
for displaying descriptive and diagnostic messages regar-
ding machine operation.
7.2 UNIT OF UNBALANCE MEASUREMENT
It is possible to select whether to display the unbalance
values expressed in grams or ounces.
7.3 UNBALANCE THRESHOLDS -
WEIGHTLESS (also see CORRECTION METHOD )
For standard balancing without WeightLess the threshold
can be preset, below which the wording “OK” appears on
the screen at the end of the run instead of the unbalance
value. The default value is 5 g. For balancing with Weight-
Less the threshold for the static rest unbalance can be set.
The value preset corresponds to the weight of a wheel with
6” width and 15” diameter. The default value is 5 g. It is
recommended to use this value, as it can be used for most
vehicles and tyres. The machine automatically calculates
the static thresholds for other dimensions and for the corre-
sponding dynamic (couple) thresholds.
The tolerance varies based on the correction method
selected.
In the case of WEIGHT LESS, set the static tolerance limit
and the average weight of a reference wheel of 6” in width
and 15” in diameter.
The following buttons are enabled:
parameter selection during setting
parameter decrease/increase during
setting
default parameter setting recommen-
ded by the manufacturer
return to previous frame.
7.4 UNBALANCE DISPLAY PITCH -
MINISTAT
This represents the unbalance display pitch and varies in
relation to the unit of measurement selected. The selection
“5g”(1/4oz)enablesdisplay of the correction values on both
sides such as to bring the static restunbalance to 0 (ideal).
It is recommended to preset this function as standard on the
machine as it improves the balancing quality. The computer
makes a complex calculation which allows cancelling the
residualstaticunbalance by varying the value and positionof
the counterweights fixed in steps of 5 grams (1/4 oz).
7.5 RUN WITH GUARD CLOSED
By selecting “ON”, the wheel balancer automatically starts
to spin when the wheel guard is lowered.
7.6 SCREEN-SAVER TIME
When the machine remains unused for longer than the
time preset with this function, the processor automatically
returns to a screen with screen-saver. Preset the time in
seconds.
7.7 WHEEL LOCKING ENABLE
Enables/disables wheel locking in the correction posi-
tion. The possible options are:
OFF: disabled
ON: enabled
ALUM : enables wheel locking in position for the ALUM
correction mode only.
You can also lock the wheel using [F1] + [STOP].
