7.1 - INCONSISTENT UNBALANCE READINGS ►
Sometimes after balancing a wheel and removing it from the balancing machine, it is foun d 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 unba-
lance 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.
8 - ROUTINE MAINTENANCE (see exploded drawings) (for non specialized personnel only
Always disconnect the machine from the mains before carrying out any operation.
8.1 - TO REPLACE THE FUSES ►
Remove the weight holder shelf to gain access to the power supply board where the fuses are located. If fuses
require replacement, use ones of the same current rating. If the fault persists, contact Technical Service.
NONE OF THE OTHER MACHINE PARTS REQUIRE MAINTENANCE.
