This gauge allows measurement of the distance of the wheel from the machine and the wheel diameter at the point
of application of the counterweight. It also allows correct positioning of the counterweights on the inside by using the

Allows lifting the wheel from the ground without using a lift in order to spin it.
It also allows lowering the wheel until it touches the ground in order to stop rotation
4.4 - MANUAL SPINNING DEVICE ►
Allows spinning the tyre until when the machine display turns off; this means that the minimum spindle rotation speed
has been reached to perform correct balancing (72’/min. for trucks and 100’/min. for cars). At this point, release the
handle and wait until the unbalance measured appears on the display. If the beep function is enabled (see

The width value (b) must be set with the buttons . The correct measurement is that which can be
measured with the compass gauge provided.

5.2.5 - UNBALANCE OPTIMIZATION ►
This ■ function serves to reduce the amount of weight to be added in order to balance the wheel.
It is suitable for static unbalance exceeding 30 g. ■
It improves the residual eccentricity of the tyre. ■
■
This operation is required if no unbalance has been measured previously; otherwise go to the next step
■
Mark with chalk a reference point on the adapter and rim.
■ With the aid of a tyre remover, turn the tyre on the rim by 180°.
■ Refi t the wheel with the reference mark coinciding between rim and adapter.
■ Perform a manual spin under normal conditions
■ RH display: percentage reduction
■ LH display: actual static unbalance which can be reduced by rotation.
■ Mark the two positions of the rim and tyre, and turn the tyre on the rim
until the positions correspond in order to obtain the optimization on the display.
■ RETURN TO MEASUREMENT SCREEN.
5.2.6
► - ALU AND STATIC MODES
From the measurement screen, press the button to select all the possible types of corrections. The (5)-LED
displays show the position where to apply the weights. If a spin has already been performed, the processor automatically recalculates, for each change of mode, the amounts of unbalance according to the new calculation.

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 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.

7.1 - INCONSISTENT UNBALANCE READINGS ►
Sometimes after balancing a wheel and removing it from the balancing machine, it is found that, upon mounting it on
the machine again, the wheel is not balanced. This does not depend on incorrect indication of the machine, but only on
faulty mounting of the wheel on the adapter; i.e. in the two mountings, the wheel has assumed a different position with
respect to the balancing machine shaft centre line. If the wheel has been mounted on the adapter with screws, it could
be possible that the screws have not been correctly tightened, i.e. crosswise one by one, or else (as often occurs) holes
have been drilled on the wheel with too wide tolerances. Small errors, up to 10 grams (0.4 oz) are to be considered
normal in wheels locked by a cone; the error is normally greater for wheels fastened with screws or studs.
If, after balancing, the wheel is found to be still out-of-balance when refi tted on the vehicle, this could be due to the
unbalance of the car brake drum or very often due to the holes for the screws on the rim and drum sometimes drilled
with too wide tolerances. In such case a readjustment could be advisable using the balancing machine with the wheel
mounted.
8 - ROUTINE MAINTENANCE (see exploded drawings) (for non specialized personnel only
Switch off the machine from the mains before carrying out any operation.
8.1 - TO REPLACE THE FUSES ►
Remove the weight holder shelf to gain access to the power supply board where the fuses are located (see Exploded
Drawings). If fuses require replacement, use ones of the same current rating.
If the fault persists, contact the Technical Service Department.
8.2 - PRECAUTIONS FOR BATTERY USE ►
To keep the battery effi cient over time, do not expose it to direct sunlight, avoid contact with liquids and do not con-
nect the output in short-circuit.
NONE OF THE OTHER MACHINE PARTS REQUIRE MAINTENANCE.
