WARNING
B EFORE SWITCHING ON THE MACHINE , MAKE SURE THAT ALL THE
CONNECTIONS DESCRIBED IN THE INSTALLATION CHAPTER
HAVE BEEN MADE CORRECTLY .
T HE FOLLOWING OPERATIONS INVOLVE A POTENTIAL RISK FOR
THE OPERATOR , GIVEN THE PRESENCE OF VOLTAGE ON THE
EQUIPMENT . T HE P ERSONAL P ROTECTIVE E QUIPMENT DESCRIBED
IN THE INSTALLATION MANUAL MUST BE WORN AND WORK
MUST BE DONE WITH DUE CARE AND ATTENTION .
O PERATIONS 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 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.
CAUTION
A NY TRACES OF DIRT MAY AFFECT BALANCING ACCURACY .
6. to turn on the wheel balancer press the switch on
the rear of the machine without touching the ma-
chine head
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 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 correct
operation of the release device.
9. In the pneumatic version, the pedal allows faste
ning/releasing the wheel on the adapter using the
collar. Press downwards to enable/disable the lock.
10. At this point, you can read the tyre measurements
and perform balancing.
11. Lower the splash guard, when fitted, and press the
START button to perform the spin.
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.
WARNING
I T IS PROHIBITED TO TOUCH ANY PART OF THE MACHINE
DURING THE BALANCING CYCLE .
