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 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 TFT monitors, see the specifi c instructions attached.
1.1.1 - Standard safety devices
►
▪ STOP push button for stopping the wheel under emergency conditions.
▪ The safety guard (option) of high impact plastic is with shape and size designed to prevent risk of
counterweighhyghts 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.
▪ Protection system on LIFT control.
1.2 - Field of application
►
The machine is designed for balancing wheels weighing up to 250 kg. It can be operated within a temperature range
of 0° to + 45°C. EMS option: can measure radial geometric deformity (run-out) with all truck wheels.

2 - HANDLING AND LIFTING
The balancing machine must be lifted only by levering on the substructure / base at the 3 specifi c fi xing
points. Other points - such as the spindle, the workhead or the accessory bench - must not be subject to any
kind of force.
Make sure that the balancing machine contacts the fl oor at all three support points. It will operate correctly without
having to be secured to the ground.
Before connecting the machine to the mains through relative cable, check that the mains voltage matches the one
shown on the nameplate at the back of the balancing machine. Rating of the electrical connection should be on the
basis of the machine electrical power consumption (see nameplate).
The machine mains supply cable should be fi tted with a plug conforming to current regulations.
▪
It is recommended to provide the machine with its own electrical connection through an automatic switch.
▪
When connection is made directly to the main control panel without using any plug, it is advisable to padlock the
▪
main switch of the balancing machine in order to limit its use to authorized personnel only.
►
3.2 - Pneumatic connection
Connection to the compressed air supply is available on the fi lter - regulator - lubrication unit located on the rear of
the balancing machine. The lift is controlled by a pedal that can be positioned ad lib (NOTE: keep away from lift movement area).The ascent and descent speed can be adjusted on the pedal according to need. The air circuit is
designed to ensure signifi cant “elasticity” of movement for the lift whatever the position of its travel; this means that
the position of the wheel can be adjusted with minimal manual effort.
3.2.1 - Extra safety devices (BP device)
►
A one-way valve prevents accidental release of the wheel should pressure be cut out during the balancing
▪
cycle.
Pressure switch to halt the motor if there is no pressure. Always actuate the unlocking control pedal with
▪
the machine stationary in order to avoid stress and abnormal wear on the adapter.
3.3 - Adapter mounting
►
Before fi tting the adapter on the shaft of the balancing machine, make sure that the shaft and the adapter centering
area are clean. Clamp the adapter on the shaft of the balancing machine. The machine can be operated with CEMB
adapters for both trucks and cars (
fi gg. 3 e 3a).The vehicle adapter is locked manually with a threaded ring
nut.

3.4 - Wheel mounting
►
The wheels should be fastened with one of the numerous adapters manufactured by CEMB.
Fasten the components to the base as illustrated in specifi c exploded view.
1.
The positions of these guards can be adjusted using the special screws accessed from inside the main support.
2.
Check that the microswitch is held down when the guard is closed.
3.
Adjust the angular position of microswitch control.

4 - CONTROLS AND COMPONENTS
4.1 - Automatic distance + diameter gauge
►
It allows measurement of the distance from the machine and the wheel diameter at the point of application of the
counterweight. It also allows correct positioning of the counterweights 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 inside the rim (for calibration, see the corresponding paragraph).
The gauge can only be used with the counterweight pincers mounted.

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

: type of correction (ALU AND STA TIC MODES)
: Vehicle/truck selection

Dimensions gauge : when extracted, the Dimensions screen is selected (PRESETTING OF WHEEL DIMEN-
SIONS).
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 or distance + diameter gauge will cause
automatic switching from the screen-save menu to the initial screen.
