5 - INDICATIONS AND USE OF THE WHEEL BALANCER5.1 - DOUBLE OPERATOR PROGRAMThis program allows memorizing the dimensions of two types of wheels. Thus two operators can worksimultaneously on two different cars using the same balancing machine. The system memorizes twoprograms with various preset dimensions.

1 - Press to select operator (1 or 2). Selection is confirmed by panel-mounted LED.

2 - Enter the dimensions (see 5.2)

3 - Press to carry out the balancing as usual and memorize the programme

With program 1 or 2 is called for subsequent balancing operations without having to newly enter

the dimensions.

5.2 - PRESETTING OF WHEEL DIMENSIONS5.2.1 - AUTOMATIC PRESETTING- Standard wheels (calibration necessary also for modes ALU 1,2,3, 4, Static)

- Set the nominal width, which is normallystamped on the rim, or proceed to measure thewidth with the caliper gauge (supplied asstandard).

5.2.1.1 - AUTOMATIC WIDTH" OPTION- Move simultaneously the gauges in the measuring position as follows:

Fig. 5C DISTANCE + DIAMETER measuring gauge

Fig. 6A WIDTH measuring gauge

When the gauges are shifted, the moving symbol (see fig. 5A) appears on the display indicating thatgauges are unstable.

- Keep the gauges in position for approx. 2 seconds.- The values memorized are indicated on the display as shown in fig. 5B.N.B.: In the event of acoustic indicator enabled (see par. 4.6.1), the storage of dimensions is followed by a

"beep".- Return the gauge to rest position.

N.B. : - If the symbol in fig. 5A remains on the display, this means that at least one of the twomeasurement gauges is not in the rest position.

- The two measurements (distance + diameter and width) can be made in different moments. In thiscase carry out the measurement (distance + diameter) first. For an accurate measurement, thegauge pins must be correctly positioned. An incorrect measurement of distance means anincorrect measurement of width; compare the value measured with the nominal width shown on therim (errors up to ½" do not usually cause remarkable residuals).

5.4 - RESULT OF MEASUREMENT

Fig. 10Inside correction Outside correction

After performing a balancing spin, the amounts of unbalance are shown on the digital readouts.Digital readouts with LED's 3- 4 lit up indicate the correct angular wheel position to mount thecounterweights (12 o'clock position). In the event of acoustic indicator enabled (see par. 4.6.1) a "beep"indicate the correct correction position.

If the unbalance is less than the threshold selected, is displayed instead of the unbalance. With

it is possible to read the values below the threshold chosen gram by gram.

5.4.1 - INDICATION OF EXACT CORRECTION POSITION IN ALU-MIn correction mode ALU-M it is possible to cancel approximations in the mounting of the counterweights byproceeding as follows:

Fig. 11

- Press push button

- Insert the correction weight in the special seat on the weight holding pliers;

- Remove the gauge taking into account that the following appears on the display:

to remove the gauge towards the outside

to move the gauge in rest position

5.4.3 - 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.

A)- Mark with chalk a reference point on the adapter and rim.- With the aid of a tyre remover, turn the rim on the tyre by 180°.- Refit the wheel with the reference mark coinciding between rim and adapter.

- 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 rim on the typeuntil the positions correspond in order to obtain the optimization on thedisplay.

ALU - 3 Combined application: clip-on weight inside and hiddenadhesive weight on outside (Mercedes). Outer weight positionis the same as ALU-2.

ALU - 4 Combined application: adhesive weight outside and clip-onweight inside.

5.4.5 - AUTOMATIC MINIMIZATION OF STATIC UNBALANCE

This program is designed to improve the quality of balancing without any mental effort or loss of time by theoperator. In fact by using the normal commercially available weights, with pitch of 5 in every 5 g, and by applyingthe two counterweights which a conventional wheel balancer rounds to the nearest value, there could be a residualstatic unbalance of up to 4 g. The damage of such approximation is emphasized by the fact that static unbalanceis cause of most of disturbances on the vehicle. This new function automatically indicates the optimum entityof the weights to be applied by approximating them in an "intelligent" way according to their position in orderto minimize residual static unbalance.

ERROR MEANING

1 No rotation signal. Could be caused by faulty position transducer, or something preventingthe wheel from turning.

2 During the measurement spins, wheel speed had dropped below 60 r.p.m. Repeat the spin.3 Unbalance too high.4 Rotation in opposite direction.5 Guard open before start of spin.7 Fault in reading the machine calibration parameters. Repeat the self-calibration.8 Fault in reading the machine calibration parameters. Repeat the self-calibration.

General fault in memory of the machine calibration parameters. Contact Technical ServiceDepartment.The width value measured is too low. Repeat the width automatic measurement making surethat the preset distance value is correct.

11 Speed too high during unbalance measurement spins.12/13/14 Difficulty in reading the analog signal. Contact Technical Service Department.

15/17 Inside/outside analog signal too high. Contact Technical Service Department.16/18 Inside/outside analog signal too high. Contact Technical Service Department.

7.1 - INCONSISTENT UNBALANCE READINGSSometimes after balancing a wheel and removing it from the balancing machine, it is found that, uponmounting 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 onthe adapter; i.e. in the two mountings, the wheel has assumed a different position with respect to thebalancing machine shaft centre line. If the wheel has been mounted on the adapter with screws, it could bepossible that the screws have not been correctly tightened, i.e. crosswise one by one, or else (as oftenoccurs) 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 isnormally greater for wheels fastened with screws or studs.If, after balancing, the wheel is found to be still out-of-balance when refitted on the vehicle, this could bedue to the unbalance of the car brake drum or very often due to the holes for the screws on the rim anddrum sometimes drilled with too wide tolerances. In such case a readjustment could be advisable using thebalancing machine with the wheel mounted.

8 - ROUTINE MAINTENANCESwitch off the machine from the mains before carrying out any operation.

8.1 - REPLACEMENT OF THE FUSESRemove the weight holder tray to gain access to the power PC board where the fuses are located (seeExploded Drawings, item 317). If fuses require replacement, use ones of the same current rating. If thefault persists, contact the Technical Service Department.

8.2 - ADAPTER TERMINAL OF P SPINDLE- Always keep the inside felt ring lubricated
