English 6. Adjusting the horizontal gap between the shearing blades Adjust the horizontal gap between the shearing blades (A in Fig. 2) at approximately 1/10 the steel plate thickness to be sheared, according to the following procedures. (Fig. 3) Moving Blade Stationary Blade Fig. 2 Thickness Gauge Stationary Blade Lock Nut M4 Slotted Set Screw M4×14 Hexagon Socket Hd. Bolt Fig. 3 (1) Loosen the hexagonal socket bolts fastening the stationary blade. Loosen the M4 lock nut, and push back the M4 slotted set screws slightly. (2) From the supplied thickness gauges, select one that is 1/10 the thickness of the panel to be cut. Thickness of each thickness gauge is marked thereon. Insert the gauge in between the blades, then tighten the hexagonal socket bolts very loosely. Next, use a screwdriver to turn the M4 slotted set screws to position the stationary blade until it hits the thickness gauge. (3) If the space between blades is larger than the thickness of the panel to be cut, there will be burrs for a less than clean cut. If the space between blades is too narrow, cutting speed will be affected. For cutting in a curved line, making the space a little bigger will make the cutting easier. (4) After adjustment, tighten the M4 nuts securely so they will not loosen during operation. (5) Securely tighten the hexagonal socket bolts fastening the stationary blade. 11
