Each time a new blade is installed, or the old blade after sharpening, the height of the knife bed should be manually adjusted to adjust the cutting amount of the blade, to avoid the accident caused by deep cutting caused by the larger height of the new blade. When cutting the knife, the main motor must be turned off, and only after stopping the operation!
The adjustment steps are:
        ① Make sure that the cutter is in the tool change state, first stop the main motor, press the main motor stop button, confirm that the main motor is at rest, and then put the cutting switch selection switch in the middle tool change position.
        ②Determine the cutting depth of the blade: Use a socket wrench to turn the nut on the end of the pulley to move the cutter bed to the lowest point, and observe whether the cutting depth of the blade is reasonable (normal cutting 0.5-1 mm).
        If the blade is in contact with only one end of the blade, it can be solved by adjusting the eccentric shaft behind the main frame.
        If the blade is worn and cannot cut the paper, the blade should be moved down in the direction of the long hole until the paper can be completely cut.
        The top knife cam can only be fine-tuned. If the adjustment range is too large, the knife hanging device must be braked off, otherwise the knife hanging device will be damaged.
