After the cutter is used for a period of time, it needs to be changed. In general, the change of the cutter and the change of the cutter are carried out at the same time. The tool change operation includes the following steps:
1 The blade is lowered to the lowest position, and it is in contact with the blade to cut off the power.
2 Loosen the bolts on the outside of the knife seat, make the blade touch the pad gently, then unscrew the bolt. The tool holder (cutter or cutter) is raised to the original position, and the blade is removed and placed on the wooden (or plastic). Inside the knife box.
3 Replace the blade. The blade is mounted on the work surface under the paper cutter. When replacing, a new blade is cut according to the length of the blade groove, and the burr on the surface of the blade is worn away by a blade or a sandpaper, and then inserted into the groove.
Special note: the blade can not be moved in the groove; the surface of the blade should be parallel to the work surface.
4 The height of the blade and the tool holder should be appropriate. Generally, the depth of the blade pressed into the pad is preferably 0.3mm to 1.5mm.
5 When replacing a new blade, make sure that the blade edge angle matches the cut resistance of the cut paper, and then wipe the blade from top to bottom with a soft cloth (the blade edge cannot be rubbed). Gently lift the blade, align the screw holes, and tighten the bolts.
Special note: The cardboard should be covered with thin cardboard, and the blade should not touch any hard objects.
6 test the knife. After the blade and the blade are replaced, the test blade can be cut empty to check whether the bolt is tightened and the blade is flat. Whether the depth of the indentation after the blade is in contact with the blade meets the requirements. If there is something wrong, it can be fine-tuned, and then a piece of newsprint or offset paper is used to test the sharpness of the blade.
Special note: Do not use a hard cut tool to test the knife to avoid damage to the new sharpening blade.
