INDICATION
The innovative IC software has been designed to reduce
the amount of weight used to correct the
unbalance, leaving a residual unbalance on the wheel
within the set tolerances.
The tolerance used by the machine is obtained from a
tolerance of a reference wheel, modified in order to
make the vibration generated by the reference wheel
comparable with that in use.
This is obtained according to the coded theory
of the ISO standards.
In general, a wheel balanced using IC has a higher
residual unbalance than a wheel balanced at best using
the conventional method, but, although generating a
tolerable vibration from the vehicle, it has the
advantage of considerably reducing the counterweights
used.

If set to ON, the wheel bulges are automatically calculated;
the calculated value can however be modifi ed by pressing

wheel is reduced to a minimum. The ‘TYRE TRAIN’ function
can be enabled and disabled from the MENU (

For best use of this function proceed
as follows:
Prepare numbered stickers to identify the wheels. 1.
Press the button 2. to start the procedure.
Mount the fi rst wheel and correctly position the radial 3.
and lateral eccentricity measurement sonars.
Balance the wheel and identify it with number 1 4. .
Repeat steps 3 and 4 for the remaining three wheels, 5.
plus the spare wheel if necessary, each time identifying
the wheel with a progressive number from 2 to 5.
Each time the spindle is opened, the wheel balancer 6.
highlights the best fi tting solution for the wheels balan
ced up to that moment. The centre of the screen shows
an outline of the vehicle with the four tyres plus
the spare; each time you spin a wheel, the number
of the wheel to be fi tted in each position on the vehicle
is indicated (front/rear axles and right/left).
The procedure can be reset at any time by pressing the 7.
button .
If the spindle is opened incorrectly, the balancing sequence
is interrupted and, consequently, the end result will be
incorrect.
To obtain an overview of the wheel balancing values, 8.
press the vehicle outline symbol.
