OPERATION: 

 
 
1. - Insert the tap holder in the “motor 

quick change” (3) and the machine is  
ready to work. 

 
2.- Clockwise rotation –tapping-: push the  

upper BUTTON (nr.1).  

 
3.- Counterclockwise rotation –unthread-: 

push the lower BUTTON (nr.2) or both 
(1 and 2) simultaneously.   

 
4. - To change the tap, pull up the quick 

change collar (3) and the tapholder will 
come out automatically.

 
*At the machines equipped with a “double-speed motor 

300/600 (rpm)

”, the speed is changed 

by turning of the “motor slide collar” (4).  
 
 
 

- Speed at 300 rpm:

 set the collar notch (4) 

at position “I”  
  

- Speed at 600 rpm:

 set the collar notch (4) 

at position “II”  

 
 
 
 
5. - Nevertheless, adjust the turning direction tapping speed according to the material properties 
       to be thread. The mentioned speed is adjusted by means the button (5) located over  the 
       radial arm. 
 
      100% means that the motor rotates at the speed being indicated on the motor.  
 

When working in hard steels and threads close to their maximum capacities, it is advisable to 
reduce the cutting speed to 80% 
 

 
- 

For machines equipped with automatic tap lubrication

:  

Provided of the tapping conditions (material, tap, diameter), adjust the tool lubrication time by 
means the potentiometer next to the speed regulator. The maximum lubrication time is of 1 
second being adjustable every 0,1 sec.     
 
 

Do not stop and re-start the machine immediately - the system will not work. Always wait 
25 seconds until all the electronic processes in the variator and the programme have been 
switched off. After 25 seconds have passed, the machine can be switched on again.
