12.4. Auto-start descent of the arm
In standard machines, the control valve of the arm descent has to be shut after the arm uplift and by the next arm descent, the descent
speed has to be set again. In this version, the control valve is additionally fitted with an electro-hydraulic valve, which remains after
the arm uplift in the set position. After saw blade start, it is automatically released and the arm descents into the cut at a set speed.
Thus, setting of the descent speed for each cut falls off. This significantly eliminates operator error and thus protects the saw blades,
and increases also productivity of the machine. An ideal help when cutting material in larger series.
Button Descent of the arm is used for setting of the stopped saw band above the material, alternatively for descent of the arm into the
low position after the cut without starting the saw blade. Speed of the descent is controled by relief valve.
