TRIMAX 520 

 

 

Page 23 

Hydraulic 3D stone control 

The  working  pressure  is  adjusted  to  around  70 bar =  green  area  on  the 
manometer (A).  The  actual  pressure  can  be  controlled  continuously  on  the 
manometer (A).  After  the  adjustments  have  been  done,  shut  the  ball  plug 
valve (B)  and  the  hydraulic  hose  can  be  disconnected  from  the  tractor.  If  the 
ball plug valve is not shut, the oil will slowly seep back to the tractor and the 
pressure  on  the  installation  will  fall,  since  the  outlet  on  the  tractor  is  not 
completely sealed.
