1- General
1.1 - General safety recommendations
- The balancing machine should only be used by duly authorized and trained personnel.
- The balancing machine should not be used for purposes other than those described in the instruction
manual.
- Under no way should the balancing machine be modifi ed except for those modifi cations made explicitly by
the manufacturer.
- Never remove the safety devices. Any work on the machine should only be carried out by duly authorized
specialist personnel.
- Do not use strong jets of compressed air for cleaning.
- Use alcohol to clean plastic panels or shelves (AVOID LIQUIDS CONTAINING SOLVENTS).
- Before starting the wheel balancing cycle, make sure that the wheel is securely locked on the adapter.
- The machine operator should not wear clothes with fl apping edges. Make sure that unauthorized personnel
do not approach the balancing machine during the work cycle.
- Avoid placing counterweights or other objects in the base which could impair the correct operation of the
balancing machine.
1.1.1 - Standard safety devices
- STOP push button for stopping the wheel under emergency conditions.
- The safety guard of high impact plastic is with shape and size designed to prevent risk of counterweights
from fl ying out in any direction except towards the fl oor.
- A microswitch prevents starting the machine if the guard is not lowered and stops the wheel whenever the
guard is raised.
1.2 - Field of application
The machine is designed for balancing car or motorcycle wheels weighing less than 75 kg. It can be operated within
a temperature range of 0° to + 45°C.
It can measure the geometric radial run-out of the wheels (optional).

NB: DO NOT HOIST THE MACHINE USING DIFFERENT GRIPS.
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.3).
It is advisable to secure the system to the ground using the specifi c feet (see Figure 3) 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 - Adapter mounting
The balancing machine is supplied complete with cone adapter for fastening wheels with central bore.
Other optional adapters can be mounted:
a) Back-off screw B and remove threaded end-piece A.
b) Fit the new adapter.

3.4 - 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.

DC
WD
Co ne
When balancing very wide wheels (9”), there is not
enough space to turn the distance gauge. To withdraw
the wheel from the machine side, fi t spacer WD on the
adapter body and secure it with the standard issue
nuts. When centring the wheel with the cone on the
inside, fi t the DC spacer to obtain spring thrust.

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 - 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 by using the specifi c function (see
OF EXACT CORRECTION WEIGHT POSITION) which allows reading, on the monitor, the position used for the measure-
ment within the rim (For calibration, see
The gauge can only be used with the counterweight pincers mounted.
GAUGE CALIBRATION).
4.3 - Automatic width gauge (optional)
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

4.4 - 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.

Dimensions gauge: when extracted, the Dimensions screen is selected (see PRESETTING OF WHEEL DIMENSIONS).
If the machine remains on the initial screen for a certain amount of time without being used, the system is automatically switched to a screen-save. Striking of any key, movement of the wheel of distance + diameter gauge will cause
automatic switching from the screen-save menu to the initial screen.
