Then loosen the fix bolt(M24 Hexagon left screw) which is in the center of blade.
Page 22: Vise Pressure Adjustment
(7) Vise Pressure Adjustment Fig.10 You can adjust vise pressure by turning the knob of reducing valve(OG- G01-P1), which is pressure control valve. The reducing valve is under right the solenoid valve(SS-G01-E3X-C1) on the hydraulic unit at the backside of machine.
Page 23: Timer Adjustment
(8) Timer Adjustment Fig.11 T1: (Pressure Switch work), It indicates the time from vise closes to saw head begins to down. T2: It indicates the time when Saw head moves up and stops after cutting to vise open. You can adjust the time by turning scale.
Page 24: Saw Head Speed Control
(9) Saw Head Speed Control This control valve, which is hydraulic flow control valve, controls the downward speed of Saw Head. To increase the downward speed of Saw Head, turn the control valve clockwise.(fig.12) To decrease the downward speed of Saw Head, turn the control valve anticlockwise.
