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).
If possible, it is advisable to anchor to the fl oor using relative mounting feet (see fi g. 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) (any extension cables must have a
cross-section of not less than 2.5 mm
2 ).
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) and 10 A (115 V).
3.3 - Pneumatic connection
For operation of the spindle with pneumatic locking (constant thrust air spring) connect the balancing machine to the
compressed air main. The connection fi tting is located at the back of the machine. A pressure of at least 7 kg/cm
2 (approx.
0.7 MPa or 7 BAR or 100 PSI) is required for correction operation of the release device.
3.4 - Extra safety devices
The wheel is always locked even when there is a pressure or power failure during the balancing cycle.
Always actuate the unlocking control pedal with the machine stationary in order to avoid stress and
abnormal wear on the adapter.
3.4.1 - Manual chuck release
If the power fails, operate as described below to release a mounted wheel :
Remove the cover on the rear of the base
Manually turn the controls 1 and 2 located on the valve
Remove the released wheel
Turn the controls back to the original position
3.5 - Adapter mounting
The balancing machine is supplied complete with cone adapter for fastening wheels with central bore. Other optional
fl anges can be mounted once the terminal part is removed (also see enclosed brochures)
N.B. : Carefully clean the coupling surfaces before performing any operation.
