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 person
▪
nel 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.
For the TOUCH SCREEN see the specifi c instructions below.
▪
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 and lateral run-out of the wheels (option).
It can print a balancing certifi cate (option).

►
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
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
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.

3.6 - Guard mounting
1.
Fasten the components to the base as illustrated in specifi c exploded view.
2.
With the guard closed check that the microswitch prod has slipped into place on the ring.
3.
If necessary, adjust the angular position of the control ring.
►
3.7 - 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, 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 spacer DC to obtain spring thrust.

Cone
The wheel is automatically locked when reaching the correct angular position for weight application on the inside and
outside, turning it slowly by hand. To unlock the wheel, turn it hard to move it from the correct correction position.
If the unbalance is within tolerance, the wheel is not automatically locked.
4.2 - Pneumatic locking pedal
►
6
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.

►
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
(
INDICATION OF EXACT CORRECTION WEIGHT POSITION ) which allows reading, on the monitor, the position
used for the measurement within the rim (for calibration,
►
4.3.1 - Distance gauge locking
The distance gauge is automatically locked when the adhesive weights have reached the correct application
distance. To release the gauge, lower it to below 10” diameter.
4.4 - 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
DIAMETER GAUGE.
►
4.5 - 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 (

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. Automatic start-up operated by the protection
system is not available from the screen-saver for safety reasons.
