If the cutter does not drop the knife, one of the reasons is that the internal components are rusted. To reduce the rusting of the internal components of the cutter, we need to do the following:
        1. Judging from the sound. If the sound of the cutter is abnormal and there is a sound that the latch cannot lock the cutter bed when the machine is shut down, you should check the functions of the cutter and other components.
        2. Protect from lubrication. To maintain a reasonable maintenance cycle and keep the cutter operating well, it is necessary to pay attention to the connection between each operating element and the oil filling point on the right side of the rear end of the fuselage. Lubricate this filling point and lithium base grease. Normal maintenance.
        3. Cultivate from the habit. One is to control the workload and the number of cuts per knife. It is necessary to avoid overloading and overloading of the cutter as much as possible; second, consider the lithographer from the machine itself, do not leave the machine in a long-term stagnation state Even if it is not working, it should be operated periodically for several strokes to prevent the related parts from corrosion.

        In addition to the points mentioned above, at the same time, we also need to develop good switch machine habits, regularly check the status of safety components, and regularly do lubrication and maintenance work, so as to better protect the paper cutter.
