Static Balancing - Corghi ProLine 650 Manual De Uso

- Spin the wheel by lowering the guard.
To obtain the most accurate results, do
not apply any undue stress to the machine
during wheel spin.
- Wait for the wheel to stop automatically
and for the calculated unbalance values
to be displayed.
- Select the first side to be balanced.
- Turn the wheel until the central element
of the corresponding position indicator
lights up.
- Apply the indicated balancing weight in
the position on the rim corresponding to
12 o'clock.
- Repeat the operations listed above for
the second side of the wheel.
- Perform a test wheel spin to check the
balancing accuracy. If it is not satisfac-
tory, modify the value and position of the
weights previously applied.
bear in mind that a counterweight position-
ing error of just a few degrees may lead to
a residual unbalance as large as 5-10 grams
during the verification phase, especially in
the case of large unbalances.
WARNING
Check that the system which fits the weight
to the rim is in optimum condition.
A weight which is not fitted properly or
correctly may come off as the wheel ro-
tates, thus creating a potential danger.
If the key is pressed whilst the
wheel is rotating, the spin will be prema-
turely interrupted.

Static balancing

A wheel can be balanced using a single
counterweight on one of its two sides or
in the centre of the well. In this case, the
wheel is balanced statically. However, there
is still the risk of dynamic unbalance, which
60
becomes more significant as the width of
the wheel increases.
- Press the
the LED corresponding to the STATIC
programme illuminates;
- press the button to confirm selec-
tion;
- set the wheel diameter value (in static
mode it is not necessary to enter the
width and distance values);
- spin the wheel by lowering the guard;
- wait for the wheel to stop automatically
and for the calculated static unbalance
value to be displayed;
- rotate the wheel until the central element
of the position indicator lights up;
- apply the balancing weight in the 12
o'clock position on either the outer or
inner side, or at the centre of the rim well,
indifferently. If applied in the well, the
weight is applied on a diameter smaller
than the rated diameter of the rim. A
value of 2 or 3 inches less than the rated
value must therefore be entered when the
diameter is set in order to obtain correct
results;
- follow the instructions specified in the
dynamic balancing procedure to perform
a test wheel spin.
Alloy wheel balancing (ALU)
Self-adhesive weights are generally used to
balance alloy wheels and are applied differ-
ently than for standard balancing (Fig. 12).
