external packaging of the product and proper
disposal of used batteries (only if contained in
the product).
Your help is crucial in reducing the amount of
natural resources used for manufacturing electri-
cal and electronic equipment, minimise the use
of landfills for product disposal and improve
the quality of life, preventing potentially haz-
ardous substances from being released in the
environment.

UNBALANCE CALIBRATION
This procedure calculates suitable correction
coefficients starting from known operating con-
ditions. It improves the machine accuracy by
correcting to a certain extent the calculation er-
rors that may result from the alteration of the
machine's features over the course of time.
CENTRING
Procedure for positioning the wheel on the
wheel balancer shaft to ensure that the shaft
axis corresponds to the wheel rotation axis.
BALANCING CYCLE
Sequence of operations to be performed by
the user and the machine from the beginning of
the spin until the wheel is braked to a stop after
calculating the unbalance values.
CONE
Conical element with a central hole which,
when inserted on the wheel balancer shaft, is
used to centre the wheels having central holes
with a diameter ranging between maximum and
minimum values.
RUNOUT
This is represented by a sinusoidal wave form
having a specific width, which indicates geo-
metric deformations in the radial direction.
Since tyres and rims are never perfectly round,
there is always a certain amount of runout (or
radial runout first harmonic) for the wheel (or
assembly). If the runout width is greater than
a specified threshold, vibrations may be gen-
erating while driving the vehicle even after an
accurate balancing was performed.
The speed at which these vibrations may be
generated depends on the structural features
of the vehicle. Generally speaking, this (critical)
speed is about 120-130 Km/h for common pas-
senger vehicles.
DYNAMIC BALANCING
Procedure for unbalance compensation by
applying two weights, one on each of the two
wheel sides.
STATIC BALANCING
Procedure for correcting only the static element
of the unbalance, by applying only one weight,
usually at the centre of the rim well. Accuracy
increases as the width of the wheel decreases.
