1.1 GENERAL
The machine has been constructed in conformity with the current EC Directives and the technical standards imple­menting the requirements, as stated in the declaration of conformity issued by the manufacturer and attached to the manual. This publication, hereinafter simply referred to as ‘man- ual’, contains all the information required to safely use and service the machine referred to in the Declaration of Conformity. This appliance, hereinafter is generically referred to as ‘machine’. The manual addresses operators instructed on the precau­tions to take in relation to the presence of electric current and moving devices. This publication is intended for all ‘users’ who as far as within their competence need to and/or are obliged to give instructions to others or operate on the machine themselves.
These persons can be identified as follows:
- operators directly involved in transporting, storing, installing, using and servicing the machine from when it is put on the market until when it is scrapped;
- direct private users.
The original Italian text of this publication constitutes the only reference to resolve any interpretation controversies related to the translation into the European Community languages. This publication forms an integral part of the machine and must therefore be kept for future reference until final dismantling and scrapping of the machine.
Any calibrations, adjustments and extraordinary mainte­nance operations are not considered in this document as they may only be performed by the service engineer who must work on the machine according to the technical and rated characteristics for which it was built.
Though it is fundamental to read this manual, it cannot replace skilled technical staff who must be adequately trained beforehand. The foreseen use and configurations of the machine are the only ones allowed by the manufacturer; do not attempt to use the machine in a different way.
Any other use or configuration must be agreed in advance with the manufacturer in writing and in this case an annex will be attached to this manual. For use, the user must also comply with the specific workplace legislation in force in the country where the machine is installed. The manual also refers to laws, directives, etc., that the user must know and consult in order to accomplish the goals that the manual sets out to achieve.
1.3 WHERE AND HOW TO KEEP THE MANUAL
This manual (and relative attachments) must be kept in a safe and dry place and must always be available for consultation. Make a copy and keep it in the archive. When exchanging information with the manufacturer or the technical assistance staff authorised by the former, quote the rating plate information and the serial number of the machine.
This manual must be kept for the entire lifetime of the machine, and if necessary (e.g.: damage making all or
some of it illegible, etc.) the user must request another copy exclusively from the manufacturer, quoting the pub­lication code indicated on the cover.

1.4 MANUAL UPGRADES
Use and Maintenance Manual Rev. 12-2012
This manual is an integral part of the machine and reflects
ENGLISH
the state of the art at the moment it was put on the market. The publication complies with the directives in force on that date; the manual cannot be considered inadequate as a result of regulatory updates or modifications to the machine.
Any manual upgrades that the manufacturer may see fit to send to users will become an integral part of the manual and must be kept together with it.
1.5 COLLABORATION WITH USERS
The manufacturer will be pleased to provide its custom­ers with any further information they may require and will consider proposals for improving this manual in order to more fully satisfy the requirements it was written for.
In case of transfer of ownership of the machine, which must always be accompanied by the use and maintenance manual, the original user must inform the manufacturer of the name and address of the new user in order to allow it to send the new user any communications and/or updates deemed to be indispensable.
This publication is the property of the Manufacturer and may not be fully or partly reproduced without prior written agreement.
- never exceed the limits of use of the machine;
- always constantly and carefully clean and service the machine;
- have the machine used by people of proven capacity and attitude, adequately trained for the purpose.
The manufacturer declines all direct and indirect liability
caused by:
- use of the machine in a different way from that indicated in this manual
- use of the machine by people who have not read and fully understood the contents of this manual;
- use in breach of specific regulations in force in the country of installation;
- modifications made to the machine, software and op­erating logic, unless authorised by the manufacturer in writing;
- unauthorised repairs;
- exceptional events.
Transfer of the machine to a third party must also include this manual; failure to include the manual automatically invalidates all the rights of the purchaser, including the terms of warranty, where applicable. If the machine is transferred to a third party in a country with a different language from the one written in this manual, the original user shall provide a faithful translation of this manual in the language of country in which the machine will operate.

3.1 MACHINE FUNCTION
It is a wheel balancing machine for cars, light commercial vehicles and 4-WDs .The wheels must weigh less than 75 kg. It can be operated in a temperature range of 0° to + 45° C.
It can operate only on a flat and non-resilient surface. Do not mount any wheels other than motorcycle, car or truck wheels on the wheel balancing machine.
Thanks to the new and exclusive VDD (Virtual Direct Drive) system, reliable unbalance measurements can be made in a short time, almost half the cycle time of other wheel balancing machines in this range.

WHEEL THE SAME AS PREVIOUS
Close the guard to perform the balancing spin. The machine in any case checks the wheel dimensions and if they are different from the previous wheel, automatically measures them again. With this innovative system you can balance a set of 4-5 wheels measuring the dimensions only once, thus saving a lot of time.
TAPER AND TREAD MEASUREMENT AT THREE POINTS
Press the button to enable/disable complete taper and tread measurement.
This function uses a special measuring cycle that extends the cycle time by a few seconds. The setting remains stored even when the wheel balancing machine is turned off.
