Before powering the machine, carry out the following
checks:
check that the balancing machine touches the floor
1.
at the three support points;
2. make sure that all the parts of the balancer are cor
rectly 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.

6. Position the wheel on the terminal with the inner part
facing the balancer;
7. Firmly attach the wheel to the balancer shaft using
the lock nut. In the pneumatic version, use the spe
cific collar provided.
For operatio
n 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 8 Kg/cm
2
(~ 0.8 MPa; ~
8 BAR; ~ 115 PSI) pressure is needed for cor
rect operation of the release device.
8. In the normal version, the pedal controls a mechani
cal brake which facilitates locking the locking ring
and positioning the wheel for correction.
In the pneumatic version, it allows fastening/relea
sing the wheel on the adapter using the collar. The
pedal has two stable positions:
upper position for
unlocking; lower position for locking the wheel.
9. The wheel is automatically locked when it reaches
the correct angular position for application of the
weight on the inside and outside by turning it slowly
by hand. To release the wheel, turn it forcefully to
move it from the correct correction position. If the
unbalance is within tolerance, the wheel is locked
automatically.
10. To switch on the balancer press the switch on the
left-hand side of the machine.
