2.1 PURPOSE
It is used to balance the wheels of cars, vans, 4-WD,
motorcycles and scooters. The wheels must weigh less than 75 kg. It can be operated in the temperature range of 0° to + 45°C.
The machine can operate only on fl at non resilient fl oor.
To lift the machine, lever only on the base where the 3 support points are located. never, under any circustance, apply force to other points such as the spindle, head, or accessory shelf. It functions properly without having to fasten it to the floor with wheels weighing up to 35 kg; for heavier wheels, fasten it at the points indicated. Do not mount anything other than motorbike, car or truck tyres on the wheel balancer.
Thanks to the new and exclusive VDD (Virtual Direct Drive) system, reliable unbalance measurements can be made in a short time, almost half the time of the cycle used with respect to other balancers in this range.

5.2 MEASUREMENT RESULT
Inside correction
ENGLISH
Outside correction
After performing a balancing spin, the amounts of unba­lance are shown on the digital readouts. Digital readouts with LED lit up indicate the correct angular wheel position to mount the counterweights (12 o’clock position). If the unbalance is less than the threshold selected,
displayed instead of the unbalance; with
sible to read the values below the threshold chosen.
INDICATION
In the case of wheels with a diameter less than or equal to 13” and at temperature conditions near 0°, the wheel balancer automatically inserts a special measuring cycle composed of two successive measurements. The accuracy of the unbalance values and the reliability of the wheel balancer remain unchanged. This type of operation is reset
each time the wheel balancer is started.
5.3 STATIC UNBALANCE
It is selected by pressing and is shown on the central
display. The position is indicated on the displays 3 and 4.

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, resident in the machine, 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. Diagnostics
7.1 INCONSISTENT UNBALANCE READINGS
In some cases, when a wheel that has just been balanced is repositioned on the balancer, the machine can detect an unbalance.
This is not a machine problem but is due to faulty mounting of the wheel on the flange. In other words, when mount­ing the wheel after initial balancing, it has taken another position with respect to the balancer shaft axis.
If the wheel has been mounted on the flange with screws, the screws may not have been tightened correctly (criss­cross sequence) or the tolerances of the holes drilled in the wheel may be too large. Small errors, up to 10 grams (0.4 oz), are to be considered normal in wheels locked with the relative cone: The error is normally greater for wheels locked with screws or studs.
If, after balancing, the wheel is still unbalanced when re­fitted on the vehicle, this could be due to an unbalanced brake drum or, very often, the tolerances of the holes drilled in the rim and drum are too large. In this case, balancing should be performed using a balancer with the wheel mounted on the vehicle.
7.2 ALARM SIGNAL
The machine has a self-diagnostics cycle which identi­fies the most frequent malfunctions during the normal work cycle. These malfunctions are processed by the system and shown on the display.

8. Maintenance
ENGLISH
8.1 GENERAL
CAUTION
BEFORE PERFORMING ANY MAINTENANCE OPERATIONS, MAKE SURE
THE MACHINE HAS BEEN DISCONNECTED FROM THE MAINS POWER SUPPLY. ALWAYS USE THE PERSONAL PROTECTIVE EQUIPMENT
INDICATED IN THE INSTALLATION MANUAL.
8.1.1 Introductory notes
This machine has been designed so as not to require rou­tine maintenance, apart from accurate periodic cleaning. It is important to keep the machine perfectly clean in or­der to prevent dust or impurities from compromising the operation of the balancer.
WARNING
THE PEOPLE RESPONSIBLE FOR CLEANING THE AREA WHERE THE
MACHINE IS INSTALLED MUST WEAR PERSONAL PROTECTIVE EQUIPMENT IN ORDER TO WORK IN SAFETY AND ACCORDING TO THE CURRENT
OCCUPATIONAL HEATH AND SAFETY REGULATIONS.
Specialist staff must be authorised and especially trained concerning the dangers that may arise during operation and the correct methods for avoiding them. They must always work with great care and pay full at­tention.
If, exceptionally, the staff removes the guards to carry out a particular specialist technical maintenance, inspection or repair job, they are required to put them back after work.
After work, staff must make sure that foreign objects, in particular mechanical pieces, tools or devices used dur­ing the operative procedure that could cause damage or malfunctions are not left inside the balancer.
For safety, before starting work, maintenance, inspection and repair staff must disconnect all power sources and take all the necessary preventive safety measures.
As well as operating frequencies, the operations described below indicate the qualifications that staff must possess in order to perform the operation.
8.1.3 Replacing fuses
Some protection fuses are located on the power board (see wiring diagrams) accessible by dismantling the weight shelf). If fuses require replacement, use ones with an identical current intensity.
As extraordinary maintenance must be performed by service staff or, in any case, by specifically authorised and trained people, is not dealt with in this manual.
8.1.2 Safety rules
Performing specialist activities on the equipment, particu­larly if the guards need to be dismounted, exposes people to serious danger due to the presence of potentially live parts.
The rules shown below must be scrupulously followed.
People must always use the Personal Protective Equip­ment indicated in the Installation Manual. During activi­ties, unauthorised people may not access the equipment and WORK IN PROGRESS signs will be erected in the department in such a way that they are visible from every place of access.
