T
HE ELECTRICAL CONNECTION MUST BE MADE BY SPECIALIZED PERSONNEL. CONNECTION TO THE SINGLE PHASE MAINS
MUST BE MADE BETWEEN PHASE AND NEUTRAL, AND NEVER, UNDERANY CIRCUMSTANCES, BETWEEN PHASE AND EARTH
(GROUND). EFFICIENT EARTHING (GROUNDING) IS ESSENTIAL FOR CORRECT MACHINE OPERATION. THE MANUFACTURER
DECLINES ALL RESPONSIBILITY AND WARRANTY IN THE EVENT OF INCORRECT CONNECTION.
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 (0,8 Kw)
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 a slow acting ▪
safety switch rated at 4 A (230 V) or 8 A (115 V);
Check that the electric circuit and socket earthing connections are correct; ▪
Always wear safety goggles when using the wheel balancer. ▪
2.3 ► - ADAPTER MOUNTING
The wheel balancer is supplied complete with
cone type adapter for fastening wheels with
central bore. The threaded terminal is fi tted
according to the drawing; it can be removed
to fi t optional adapters.
CEMB produces numerous fl anges which can
be used to assemble any wheel type (see
enclosed). The use of non-original accessories
is not recommended, since these could prejudice measurement quality.

The SPLIT function is used to position the adhesive weights behind the wheel spokes (angle > 18°) so that
they are not visible. This function should be used in ALU mode where the adhesive weight is applied on the
outside. Input the wheel dimensions and do a spin.

To calibrate the machine, operate as follows:
Fit a medium-sized wheel with steel rim on the shaft. Example: 6” x 15” (± 1”) best with less then 20 g unbalance. ▪
Take the exact measurements of the wheel mounted as described in ▪ PRESETTING OF WHEEL DIMENSIONS.
PRESETTING OF INCORRECT DIMENSIONS WOULD MEAN THAT THE MACHINE IS NOT CORRECTLY CALIBRATED, THEREFORE ALL SUB-
SEQUENT MEASUREMENTS WILL BE INCORRECT UNTIL A NEW SELF-CALIBRATION IS PERFORMED WITH THE CORRECT DIMENSIONS!
Perform a manual spin under normal conditionsa.
b. Add a 60 gr. (2.00 oz) sample weight on the out

6.1 - INCONSISTENT UNBALANCE READINGS ►
Sometimes after balancing a wheel and removing it from the balancing machine, it is found that, mounting it
on the machine again, the wheel is not balanced. This does not depend on incorrect indication of the machine,
but only on faulty mounting of the wheel on the adapter, i.e. in the two mountings the wheel has assumed a
different position with respect to the balancing machine shaft centre line. If the wheel has been mounted on
the adapter with screws, it could be possible that the screws have not been correctly tightened, i.e. crosswise
one by one, or else (as often occurs) holes have been drilled on the wheel with too wide tolerances. Small
errors, up to 10 grams (0.4 oz) are to be considered normal in wheels locked by a cone; the error is normally
greater for wheels fastened with screws. If, after balancing, the wheel is found to be still out-of-balance when
refi tted on the vehicle, this could be due to unbalance of the car brake drum or very often due to the holes
for the screws on the rim and drum sometimes drilled with too wide tolerances. In such case a readjustment
could be advisable using the balancing machine with the wheel mounted on the car.
