Page 5: General Precautions
1. GENERAL PRECAUTIONS Before operating the balancing machine, read carefully the use and maintenance manual. The noncompliance with these standards frees the constructor from any responsibility. 1.1. Warnings and cautions The machine is to be operated only by authorized personnel. Check that the use of the balancing machine does not trigger off hazardous situations to people or things. - Page 6 3 INSTRCUTIONS FOR USE 3.1 Lifting and Installation Lever the base to lift the balancing machine. In no circumstances should and force be applied to other parts, such as the mandrel, the headstock, the casing or the accessories tray. 3.2 Power supply Before connecting the machine to the mains with the cable provided, check that the voltage is the same as shown on the plate mounted on the back of the balancing machine.

Never use the pincers for the counterweights or other pointed objects. 3.3 Fixing the adapter Before fixing the adapter on the balancing machine shaft, check that the shaft and the adapter centering area are clean. Use one of the many adapters produced as per catalogue.
- Page 8 provided. DISTANCE: find out the measure between the machine and the weights application point on the wheel rim and set by means of “a” 3.7 Note for balancing of motorcycle wheels dynamically Slip the extension onto the distance measurer. Extract the measurer until the +5 cm extension touches the inner side of the wheel rim.
- Page 9 Add a 100 gram weight on the outside in any angular position. Press START . The machine is calibrated at the end of the cycle. The display reads “END CAL”. Remove the 100 gram weight from the wheel, which can now be balanced with a further cycle. The values that the machine records form this self-calibration operation are automatically stored in a special memory which also maintains them when the machine is switched off, with storage lasting for about 10 years, so the machine will be ready for correct functioning every time it is switched on.

The displays now read as follows: Right hand display: % value (symbol ) of possible unbalance reduction compared to the current condition of the wheel . Left hand display: Current static unbalance value. This is the value that can be reduced by the figure ,read off the right hand display by turning the tire on the rim. -

When the power or computer board requires replacement, repeat the self-calibration of the balancing machine. N.B. When the computer board is replaced , preset the machine parameters indicated on relative nameplate. 6.1-CHECKING AND SETTING OF STATIC VALUE (STI) Carry out self-calibration Wheel balancing.
