Kind reminder: Only in the "cut pile" state will the yarn be automatically cut. In the "loop pile" state, scissors are needed to cut yarn. If you encounter a problem where the scissors cannot cut the thread, you can refer to the FQA and operation video in the manual. To prevent the scissors from becoming dull, it is recommended to regularly add some oil to the machine. The use and conversion of loop velvet and cut velvet can refer to the instructions and product videos.
