If you have a sewing machine at home, the most basic things you need to master are: how to install the needle, change the presser foot, change the bobbin, thread the thread, wind the bobbin, clean the feed dog, adjust the stitch distance, adjust the stitches, etc., just read the instruction manual If you don't have an instruction manual, you can find a tutorial on the Internet. The running-in part is the core part of the machine. Don't move it lightly, but you must know where to oil it and lubricate it frequently to ensure it can work normally. Remember, be sure to use special lubricating oil for sewing machines, and never pour cooking oil at home into it. A fan didn't understand, and felt that the machine should be oiled, so he drank a lot of cooking oil on the sewing machine, but the sewing machine would not work at all. Ask the editor if there is any trick? The editor didn't have any advice, but I went to the Internet to help her find it. Some people suggested to use gasoline or kerosene to scrub repeatedly. I don't know if it will help.
