How to properly maintain a paper cutter is actually a very sophisticated science. Today we come to understand how to do it.
         First of all, the oil used varies according to the season. For example, in winter, it is best to use No. 20 engine oil to make it easier to flow; in summer, it is recommended to use No. 30 engine oil, which has a better viscosity.
         Secondly, the hydraulic pressure should be kept appropriate. If the pressure is too large, the sealing facilities may be damaged, but if the pressure is too small, the entire cutter will be sluggish and weak.
         In addition, the equipment should be lubricated frequently. Lubricating oil is essential. Adding lubricating oil in time can make the whole machine run smoothly, and after adding the lubricating oil, the cleaning of the paper cutter will become convenient.

         Finally, it is recommended to use some paraffin to apply the blade when the cutter is working, this can effectively make the cut more smooth and neat.
