1 ► .1 - GENERAL SAFETY RECOMMENDATIONS
The machine should only be used by authorized and suitably trained personnel.
Do not use the machine for purposes other than those specifi ed in this manual.
The machine should not be modifi ed in any way except for those modifi cations explicitly carried
out by specialised personnel.
Never remove the safety dehyvices. Any work on the machine should only be carried out by
specialised personnel.
A
void using strong jets of compressed air for cleaning.
Use alcohol to clean the plastic panel 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 avoid wearing clothes with fl apping edges. Make sure that unau-
thorized personnel do not approach the machine during the work cycle.
Avoid placing objects inside the cabinet as they could impair the correct operation of the
machine.
For the TOUCH SCREEN see the specifi c instructions below.

1.1.1 - STANDARD SAFETY DEVICES
S ▪ TOP 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- GENERAL
1.2 - FIELD OF APPLICATION ►

2.2 - 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
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 16A (230V).

).
2.3 - 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 8 kg/cm
0.8 MPa or 8 BAR or 115 PSI) is required for correction operation of the release device.

(approx.
2.4 - EXTRA SAFETY DEVICES ►
T ▪ he 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

► .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 ▪

2.5 - WHEEL MOUNTING ►
The wheels should be fastened with one of the numerous adapters manufactured by the manufacturer (see enclosed
brochures). Incorrect centering inevitably causes unbalance.

3 - CONTROLS AND COMPONENTS
3.1 ► - PNEUMATIC LOCKING PEDAL
3
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 two stable positions: top,
wheel unclamped; bottom, wheel clamped.
3.2 - 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 rim by using the specifi c function
(
INDICATION OF EXACT CORRECTION WEIGHT POSITION ) which allows reading, on the monitor, the position
used for the measurement within the rim (for calibration
3.3 ► - SONAR DEVICE FOR AUTOMATIC WIDTH MEASUREMENT
Measures the distance of the wheel without mechanical contact simply by closing the guard every time a valid measurement has been made with the
AUTOMATIC DISTANCE AND DIAMETER MEASUREMENT GAUGE.
CALIBRATION).
3.4 - ► CLOCK CONTROL
The wheel balancing machine is provided with a clock having a back-up of about one month with the machine
switched off. If the machine remains unused for a long period, check date and time settings when restarting (
CLOCK SET-UP).
3.5 - P ► RINTER (OPTION)
Used to print useful information for the vehicle, residual imbalance and eccentricity for the balanced tyre.

4 - USE OF THE WHEEL BALANCER
The monitor shows several information and suggests various alternative ways of use to the operator.
This is through various “screens”.

Dimensions gauge: when extracted, the Dimensions screen is selected ( 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. Pressing on any point on the screen, movement of the wheel of distance + diameter
gauge will cause automatic switching from the screen-save menu to the initial screen. Automatic start-up operated
by the protection system is not available from the screen-saver for safety reasons.
