must be retained for the whole operating life of the 

machine.

Carefully  study  the  warnings  and  instructions  con-
tained in this manual. It contains important instruc-
tions  regarding 

FUNCTIONING, SAFE USE and 

MAINTENANCE.

KEEP THE MANUAL IN A KNOWN,

SERIOUS DANGERS.

1.1 Introduction

Thank you for purchasing this wheel balancer. We feel 
sure you will not regret your decision.
This  machine  has  been  designed  for  use  in  profes-
sional  workshops  and  stands  out  for  its  reliability 
and easy, safe and rapid operation. With just a small 
degree of maintenance and care, this wheel balancer 
will give you many years of trouble-free service and 
lots of satisfaction.

2.0  INTENDED USE

The machine described in this manual , and their 
different versions, 

 

is a wheel balancing machine 

for  car  and  light  transport,  projected  to  be  used 

exclusively to cancel out, or at least reduce to ac-
ceptable limits the vibrations of the wheels, by fitting 
counterweights, of suitable size and in specific posi-
tions to the wheels that are not correctly balanced.

EMPLOYING THIS MACHINE OUT-

SIDE THE USE DESTINATION IT 

HAS BEEN DESIGNED FOR (AS 

INDICATED IN THIS MANUAL) IS 

INAPPROPRIATE AND DANGER-

OUS.

THE MANUFACTURER CANNOT 

BE HELD RESPONSIBLE FOR ANY 

DAMAGE CAUSED BY IMPROPER, 

ERRONEOUS, OR UNACCEPTABLE 

USE.

2.1 

Training of personnel

The machine may be operated only by suitably 

trained and authorized personnel.

Given the complexity of the operations necessary to 
manage the machine and to carry out the operations 
safely and efficiently, the personnel must be trained 
in  such  a  way  that  they  learn  all  the  information 
necessary to operate the machine as intended by the 
manufacturer.

A CAREFUL READING OF THIS 

INSTRUCTION MANUAL FOR 

USE AND MAINTENANCE AND A 

SHORT PERIOD OF TRAINING 

WITH SKILLED PERSONNEL CAN 

BE ENOUGH PREVENTIVE PREPA-

RATION.
