13.2 -- ELECTRICAL CONNECTION 
Verify that voltage and power frequency are compatible with the range reported on the identification plate. Variations 
of more than 10% cause working anomalies, which can be either significant or not. 
  
The power cable is complete with a pin that complies with CEE  Norms. If  it is not of the same type  used in 
your  premises,  it  will  have  to  be  replaced  (this  should  be  done  by  skilled  personnel,  for  example  an 
electrician).  
 

The phasing performed by the manufacturer allows to get a correct rotation of all motors by connecting the 

wires in the following order: L1=R, L2=S, L3=T, 
The control box of the picture below is the “stand alone” model , to be placed at floor .  The “built-in machine” model 
has the same controls and functining . 
Verify the correct working as follows (the blade protection structure must be closed): 
a) if the EMERGENCY BUTTON – picture RI0416, No. 1 - is pushed, turn it 1/4 of a round in the direction shown on 
the button. 
b) push the button ON of the main switch – picture RI0416, No. 2 , the WHITE lamp must turn on.  
 

.

     

 

c) push the yellow button RESET – picture RI0421, No. 6 - for 6/10 seconds to start the hydraulic unit motor (all the 
GREEN lamps can turn on as well) and check the sawframe motions:  
BLACK button (picture RI0421, No. 2): the sawframe drops (you can change the down-feed speed by means of the 
speed selector – picture RI0421, No. 5). 
RED button (picture RI0421, No. 8): the sawframe stops and  lifts if you continue pushing. 
 
If this does not happen, turn off the machine by means of the main switch, disconnect the feeding plug in and 
reverse the connection of two of the wires inside the pin, with exclusion of the green or yellow earthing cable. 
Start again from point a) 
 
d) switch –off  the saw by pushing the button OFF on the main switch (picture RI0416, No. 2). You can place as much 
as 3 locks – picture RI0416, No. 3 – on this switch to prevent unauthorized access to the equipment 
  
If no button is pushed for 10/15 minutes, the electronic panel disable the hydraulic unit motor. 
 To start it again, push the yellow button – picture RI0421, No. 6. 
 

In  case  an  external  tension  transformer  is  supplied,  put  it  in  a  safe  place  away  from        the 

loading/unloading area. 
 
  14 - BLADE TENSION 
This  machine  is  supplied  with  a  blade  which  is  already  tensioned,  so  as  to  allow  the  motor  to  start  (as  a 
matter of fact, it doesn’t work if the blade doesn’t have the right tension).   
Before starting, we suggest you to verify what follows:
