The operation of the paper cutter is simple, and the environmental adaptability is also relatively good. Usually work can be carried out in the workshop to ensure stable power supply. Generally, the paper cutter has an automatic switch system. As long as the paper is set, and then the start button is pressed, the cutter will automatically rotate to shred the paper. There are also some advanced paper cutters that only need to press the start button once, and the cutter will rotate to continue cutting. After the shredding is completed, the stop button should be pressed to stop the cutter from rotating, and the paper scraps on the cutter should be cleaned in time. Most paper cutters are now equipped with overload and power-off newspaper devices, that is, when the motor of the cutter is overloaded and runs hot, it will automatically stop. At this time, use should be stopped for 20 to 30 minutes to allow the motor to cool. At the same time, the amount of input paper should be appropriately reduced when it is used again.
