INTRODUCTION 

The electronic balancing machine with a microprocessor, capable of balancing wheels weighing up to 65Kg. 

The control elements and signals are all contained on the front panel. 

The keyboard calibration system also provides a sufficient adjustment range to cope with unusual wheels (aging motorcycles 

and cars). 

Some  ALU  functions  are  available  for  specially  shaped  wheels  or  for  presetting 

optional balancing machine functions (see 3.5 using the keyboard).

INSTRCUTIONS FOR USE 

3.1 Lifting and Installation 

Lever  the  base  to  lift  the  balancing  machine.  In  no  circumstances  should  force  be 

applied  to  other  parts,  such  as  the  mandrel,  the  headstock,  the  casing  or  the 

accessories tray. 

It is advisable but not obligatory to fix the machine to the floor, using the φ12 holes in 

the three support feet (access to two is obtained by removing the adapter support). 

Check that the balancing machine touches the floor where the three feet rest.                                           

Maximum dimensions including the guard: 1250X1100X1700mm. (See Fig.2) 

Fig. 2 

3.2 Power supply 

Before connecting the machine to the mains with the cable provided, check that the voltage is the same as shown on the plate 

mounted on the back of the balancing machine. 

Standard voltage is 220-240 V or 110 V single phase. Maximum electrical power input is 0.6KW.
