2.1 PURPOSE
The ER80/ER80 SE is used to balance the wheels of cars,
vans, 4-WD, motorcycles and scooters. The wheels must
weigh less than 75 kg. and, when fitted on the balancing
machine, must not interfere with any fixed part of the
machine, excluding the shaft and support adaptor.
The machine is supplied with equipment enabling the
vast majority of car wheels available on the market to be
fitted. Other wheels with special dimensions, geometry
and centring require special adaptors supplied on request.
The machine can operate only on at non resilient oor.
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. Do not
mount anything other than motorbike, car or truck tyres
on the wheel balancer.

5.1 PRESETTING OF WHEEL DIMENSIONS
The balancing data is set by means of an “intelligent” au-
tomatic gauge; con rmation of the measurement and the
position appear on the display. The round part of the gauge
must rest on the rim where the weight will be positioned.
b) adhesive weights: make two successive measurements
on two correction planes inside the rim.
The balancing machine automatically interprets that the
correction will be made with adhesive weights and the
following appears:

5.2 MEASUREMENT RESULT
After performing a balancing spin, the unbalance values
are shown on the displays 1-2. The symbol shown on the
LED displays 3-4 and highlighted in the figure indicates the
correct angular position of the wheel in order to apply the
counterweights (12 o’clock for clip-on weights; 6 o’clock
with laser indication for adhesive weights to be applied
inside the rim).
If the wheel clamp option is enabled (see

MENU), the
of the weight application distance is accompanied by
a beep.
If gauge locking is enabled (see MENU), the gauge
is automatically locked in position to prevent weight
application problems. To release the gauge, lower it
towards the spindle, or if this is not possible, move the
wheel.
▪ Rotate the gauge until the correction weight adheres
to the rim

This program is designed to improve the quality of balancing
without any mental effort or loss of time by the operator. In
fact by using the normal commercially available weights, with
pitch of 5 in every 5 g, and by applying the two counterweights
which a conventional wheel balancer rounds to the nearest
value, there could be a residual static unbalance of up to 4
g. The damage of such approximation is emphasized by the
fact that static unbalance is cause of most of disturbances
on the vehicle. This new function, resident in the machine,
automatically indicates the optimum 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.

on the rim and the ange coincide.
Close the guard to perform a spin.
6.3 SELF-DIAGNOSTICS
The machine can perform self-diagnostics to check the
LED’s on the control panel and make sure the encoder
reads correctly.
To perform this operation, view the SETUP menu.
In the self-diagnostics sequence, all the LED’s on the panel light up for a few seconds in order to check operation.
When the LED’s go out, the machine automatically moves
on to the encoder reading phase. When the wheel is turned
manually (forwards and backwards), the display shows its
exact position. The value lies between 0 (zero) and 255.

7.1 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.
This is not a machine problem but is due to faulty mounting
of the wheel on the flange. In other words, when mounting 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 (crisscross sequence) or the tolerances of the holes drilled in
the wheel may be too large. Small errors, up to 10 grams
(0.4 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 refitted 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.
7.2 ALARM SIGNAL
The machine has a self-diagnostics cycle which identifies the most frequent malfunctions during the normal
work cycle.
These malfunctions are processed by the system and
shown on the display.
