CHAPTER 2 – GENERAL INFORMATION 

2.1       GENERAL SAFETY  
 

 

The wheel balancing machine should only be used by duly authorized and trained personnel. 

 

The wheel balancing machine should not be used for purposes other than those described in the 
instruction manual. 

 

Under no way should the wheel balancing machine be modified except for those modifications 
made explicitly by 

THE MANUFACTURER

 

Never  remove  the  safety  devices.  Any  work  on  the  machine  should  only  be  carried  out  by 
specialist personnel. 

 

Avoid using 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  avoid  wearing  clothes  with  flapping  edges.  Make  sure  that 
unauthorized personnel do not approach the machine during the work cycle. 

 

Avoid placing objects inside the base as they could impair the correct operation of the machine. 

 
2.2

 

      STANDARD SAFETY DVICES 

 

 

Stop key for stopping the wheel under emergency conditions. 

 

A wheel guard of high impact plastic that is designed to prevent the counterweights from flying 
out in any directing except toward the floor. 

 

A switch interlock system prevents the machine from starting if the guard is not lowered and 
stops the wheel whenever the guard is raised. 

 

2.3

 

      I

NTENDED USE

 

 

 

This 

wheel  balancer  has  been  designed  and  manufactured  exclusively  for  balancing  wheel 

with a maximum diameter of 1000mm and maximum weight of 75kg. The calibration system 
is sufficient to cover different wheels from motorcycles to cars.

 

 

In

  particular 

THE  MANUFACTURER 

cannot  be  held  responsible  for  any  damage  caused 

through the use of wheel balancer for purposes other than those specified in this manual, and 
therefore inappropriate, incorrect and unreasonable.

 

 

 

2.4       GENERAL CHARATERISTICS 

 

 

Automatic weight positioning where the balancing weight has to be applied  

 

Automatic braking after spin 

 

Automatic start/stop when the hood is lowered/raised 

 

Automatic application of adhesive weights on unbalanced positions  

 

STOP pushbutton to stop the machine immediately 

 

Static and dynamic balancing modes 

 

Four ALU modes  

 

Rapid optimization (OPT) 

 

Self-diagnosis 

 

Self-calibration 

 

Exceptional stability in reading the unbalance between planes
