1. Try not to use the manual paper cutter in a humid or dusty environment, and apply professional lubricating oil regularly.
2. The manual paper cutter is not recommended to cut metal or too high hardness, which will damage the blade.
3. When cutting, pay attention to whether there are foreign objects such as staples on the document.
4. Do not place the paper skewed when placing it. It is recommended that the narrower paper be placed in the middle of the paper inlet.
