Machine description
It is used to balance the wheels of cars, vans, 4-WD, motorcycles and scooters. The wheels must weigh less than 75
kg. and, when fitted on the balancing machine, must not interfere with any fixed part of the machine, excluding
the shaft and support adaptor. The machine is supplied with equipment enabling the vast majority of car wheels
available on the market to be fitted. Other wheels with special dimensions, geometry and centring require special
adaptors supplied on request (consult the attached sheet “ORIGINAL ADAPTORS”). The machine can operate
only on flat non resilient floor.
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.

Before switching on the machine, make sure that all the connections described in the INSTALLATION chapter
have been made correctly.
The following operations involve a potential risk for the operator, given the presence of voltage on the equipment.
The Personal Protective Equipment described in the INSTALLATION manual must be worn and work must be done with due care and
attention. Operations may only be performed by a specialised technician.
Before powering the machine, carry out the following checks:
1. Check that the balancing machine touches the floor at the three support points.
2. Make sure that all the parts of the balancer are correctly connected and fixed.
3. Make sure that the parameters (voltage and frequency)
of the mains power supply are compatible with
those indicated on the rating plate of the balancer.
4. Make sure the power cable is correctly connected.
5. Make sure the machine shaft and flange hole are clean.
Any traces of dirt may affect balancing accuracy.
6.
To turn on the wheel balancer press the switch on the side or back of the same; for the models with

7. Position the wheel on the terminal with the inner part facing the balancer.
8. Firmly attach the wheel to the balancer shaft using the lock nut. In the pneumatic version, use the
specific collar provided. For operation of the spindle with pneumatic locking (constant thrust air
spring) connect the wheel balancer to the compressed air mains. The connection fitting is located
at the back of the machine. At least 7 kg/cm2(~ 0.7 MPa; ~7 bar; ~105 psi) pressure is needed for
correct operation of the release device.
9. In the pneumatic version, the pedal allows fastening/releasing the wheel on the adapter using the collar.
10. At this point, you can read the tyre measurements and perform balancing.
11. To perform the spin, lower the splash guard, when fitted and, if necessary and available, press the START
button.
12. The wheel is automatically locked when reaching the correct angular position for weight application
on the inside and outside, turning it slowly by hand. To unlock the wheel, turn it hard to move it from the correct
correction position. If the unbalance is within tolerance, the wheel is locked automatically.
It is prohibited to touch any part of the machine during the balancing cycle.
