3.1 - ANCHORING
The machine can be operated on any fl at non-resilient fl oor.
Make sure that the machine rests solely on the three support points provided (fi g. 2a).
It is advisable to secure the system to the ground using the specifi c feet (see Figure 2a) in the
event of continual use with wheels weighing over 35 Kg.
3.2 - ELECTRICAL CONNECTION
The machine is supplied with a single phase mains cable plus earth (ground).
The supply voltage (and mains frequency) is given on the machine nameplate. It may NOT be changed.
Connection to the mains should always be made by expert personnel.
The machine should not be started up without proper earth (ground) connection.
Connection to the mains should be through a slow acting safety switch rated at 4A (230V) or 10A (115V) .
3.3 - PNEUMATIC CONNECTION (Versions SE)
For operation of the spindle with pneumatic locking (costant thrust air spring) connect the balancing to the
compressed air main. The connection fi tting is located at the back of the machine. At least 7 Kg/cm2 (~ 0.7
MPa; ~ 7 BAR; ~ 100 PSI) pressure is needed for correct operation of the release device.
3.4 - EXTRA SAFETY DEVICES (VERSION SE)
- Wheel always locked even when there is pressure failure during the balancing cycle.
- Rotary block wheel retainer which, in the event of accidental pressing of the pneumatic locking
pedal during the balancing cycle, avoids risk of the wheel slipping from the adapter.
- Always actuate the unlocking control pedal with the machine stationary in order to avoid stress
and abnormal wear on the adapter.
3.5 - ADAPTER MOUNTING
The balancing machine is supplied complete with cone adapter for fastening wheels with central bore.
Other optional adapters can be mounted:

threaded end-piece A.
b) Fit the new adapter SPINDLE WITH PNEUMATIC LOCKING
a) Unscrew rod B.
b) Unscrew end-piece A.
c) Fit the new adapter.
If there is no pressure, to remove the wheel,
merely unscrew rod B to its full extent.
