Under the condition of power supply and ventilation, step on the foot switch. When the upper knife is pressed down, release the hand slide valve, and then release the foot switch to stop the upper knife at the bottom. Use a 4mm hexagon key to adjust eight headless screws until the lower cutter is parallel to the upper one, and then lock the five knife pressing screws.
When cutting common substrates, the upper and lower blades a and B are located on the same plane. For products with strong cutting toughness, loosen the four screws C in the figure above. Adjust the lower cutter and its holder to the left at the same time, and the adjustment range should not exceed 0.1 mm. Then, adjust the lower knife by 0.10-0.20 mm to make the upper and lower cutters intersect to a certain extent, After adjustment, screw C is locked. After the new machine is cut for a period of time, it may not be separated. Step on the foot switch and push the eight headless screws down evenly to make the lower knife rise. The single adjustment should not exceed 0.1 mm to prevent the upper and lower knives from colliding.
