3.3 Fixing the adapter 

Before fixing the adapter on the balancing machine shaft, check that the shaft and the adapter centering area are clean. 

Use one of the many adapters produced as per catalogue. 

Remember  that  imperfect  centering  provokes  unbalanced.  Use  the  wrench  provided  to  lock  the  adapter  onto  the  balancing 

machine shaft. 

 

3.4 Mounting the wheel 

Mount the wheel with suitable cone and adjustable nut Remember that imperfect centering provokes unbalanced unnecessarily. 

 

3.5 Using the keyboard 

The following operations can be carried out using the keyboard: 

Varying the distance (dimension “a”)--------------------------------------------------------------- 
Varying the width (dimension “b”)------------------------------------------------------------------- 
Varying the diameter (dimension: “d”)------------------------------------------------------------- 

Recalculating the values------------------------------------------------------------------------------ 

Disp. The values below the threshold------------------------------------------------------------- 

Static Dynamic------------------------------------------------------------------------------------------ 

ALUx Dynamic------------------------------------------------------------------------------------------ 

Balancer self-calibrating------------------------------------------------------------------------------ 

Start by closing the guard----------------------------------------------------------------------------- 

Unbalance measured in gm or oz------------------------------------------------------------------ 

Width measured in mm or inches------------------------------------------------------------------- 

Diameter measured in mm or inches-------------------------------------------------------------- 

Start measuring cycle---------------------------------------------------------------------------------- 

Emergency cycle stop---------------------------------------------------------------------------------- 

The  unit  of  measurement  chosen  for  the  unbalance  (grams  or 

ounces) and the option to start by closing the guard or by pressing 

the  START  key  are  stored  in  the  machine’s  memory  when  it  is 

switched off. 

If the unit of measurement selected for the width and diameter (mm 

or inches) is inches, this selection must be repeated every time the 

machine is started up. 

3.6 Calibrating the panel 

DIAMETER: input the diameter “d “ which is shown on the tire. 

WIDTH: input the width "b", which is normally shown on the wheel 

rim, or measure the width “b” with the calipers provided. 

DISTANCE: find out the measure between the machine and the 

weights positioning point on the wheel rim and set by means of “a” 

(Fig.4)

Note for balancing of motorcycle wheels dynamically 

-

 

Slip the extension onto the distance measurer. 

-

 

Extract the measurer until the extension touches the inner side of 

the wheel rim.

   

-

 

Read the value “ a ” on the scale, set it manually using the key 
9, value “a+5” (scale base 25 cm).
