2 - HANDLING AND HOISTING
N.B. DO NOT HOIST THE MACHINE BY LEVERING UNDER THE CABINET
Fig. 2 |
Fig. 2 A |
I 0201 GB - 4
3 - COMMISSIONING
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).
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 amp (230V) or 10 amp (115V) .
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/cm2 (approx. 0.7 MPa or 7 BAR or 100 PSI) is required for correction operation of the release device.
3.4 - TO REPLACE THE ROLL OF LEAD
(for machines provided with the dispenser option) a) Open the cabinet door.
b) Mount the roll and insert the strip of lead under the rubber covered wheel; for easier insertion, act on pin (1).
c) Close the cabinet.
d) Press the push buttons to dispense a counterweight with relative cutting.
N.B. - Mount the roll of lead correctly on the spool (2)
-Never carry out point d) with the cabinet open.
-When the roll of lead is close to finishing (last 2-3 rounds of strip), lift the lead from the spool to decrease its curvature.
-Avoid bending the lead strip: the presence of strong bends and counterbends would impair correct operation of the feed system.
-If the dispenser is not used for a long period, it could be possible that the first weight to
be distributed is not accurate, therefore it should be discarded.

I 0201 GB- 5
3.5 - EXTRA SAFETY DEVICES
- 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.
3.6 - ADAPTER MOUNTING
The balancing machine is supplied complete with cone adapter for fastening wheels with central bore. Other optional adapters can be mounted; hardened shaft and tapers.
Fig. 4 Fig. 4
C68 Professional |
a) Unscrew rod B. |
|
b) Unscrew end-piece A. |
|
c) Fit the new adapter. |
N.B. If there is no pressure, to remove the wheel, merely unscrew rod B to its full extent.
3.7 - GUARD MOUNTING AND ADJUSTMENT
a)Fasten the components to the base as illustrated in specifi c exploded view.
b)The position of the wheel guard when closed can be adjusted with relative screw accessible at the back. Correct position is the one which keeps the tube exactly horizontal with wheel guard closed.
c)Check that the microswitch is held down when the guard is closed.
d)Adjust the angular position of microswitch control.
3.8 - SPACER WD
When balancing very wide wheels (9”), there is |
|
not enough space to turn the distance gauge. |
|
To withdraw the wheel from the machine side, |
SPACER WD |
fi t spacer WD on the adapter body and secure |
|
it with the standard issue nuts. When centring |
Spring |

4 - CONTROLS AND COMPONENTS
4.1 - BRAKE PEDAL
This pedal allows the operator to hold the wheel when fi tting the counterweights. It must not be actuated during the measuring cycle.
4.2 - PNEUMATIC LOCKING PEDAL
This pedal allows releasing the device fastening the wheel on the adapter. Do not actuate this pedal during the machine cycle and/or when adapters other than the standard cone adapter are mounted.
The pedal has a stable position; UP to clamp the wheel, held DOWN to release it.
4.3 - AUTOMATIC DISTANCE AND DIAMETER GAUGE
This gauge allows measurement of the distance of the wheel from the machine and the wheel diameter at the point of application of the counterweight.
It also allows correct positioning of the counterweights on the inside rim by using the specifi c function (see Indication of exact correction weight position ) which allows reading, on the monitor, the position used for the measurement within the rim (For calibration, see Calibration).
The gauge can only be used with the counterweight pincers mounted.
4.4 - AUTOMATIC WIDTH GAUGE (Option)
Width gauging is through a SONAR device which measures the distance of the wheel without mechanical contact, merely by closing the guard and each time a valid measurement has been made with gauge 4.3.
4.5 - COUNTERWEIGHT DISPENSER (Option)
The dispenser consists of a mechanism, controlled by the measuring instruments, designed to distribute a counterweight equivalent to the measured weight, thus avoiding the approximations of commercial counterweights. The counterweight is cut to the exact weight even if the approximate weight appears on the displays. Accuracy of the weight is ± 1 gram. To dispense the counterweight, press relative function push button for each side. The dispenser is operated pneumatically and uses the max. inlet pressure which should be at least 7 kg/cm2 .
4.6 - AUTOMATIC WHEEL POSITIONING
At the end of the spin, the wheel is positioned according to the unbalance on the outside or else according to the static unbalance (when selected).
Accuracy is ± 20 degrees.
4.7 - CLOCK CONTROL
The wheel balancer is provided with a clock having a back-up of about one month with the machine switched off. If the machine remains off for a long period, at the fi rst switch on, check the date and time
(see Clock set-up), adjusting them if necessary.
