ADJUSTING THE HYDRAULIC PUMP PRESSURES:  

1.  main pressure – preset from the factory, not necessary to change 
2.  saw-band tensioning pressure – with tensiometer  
3.  main vice jaw pressure – adjust according to the size and weight of the material; the lower the pressure, 

the longer the life of mechanical parts of the vice.

SETTING PRESSURES  

The pressures are pre-set in the factory – we strictly recommend no change. Leave potential adjustment to 
the  maintenance service.
