Then thread and sew the rag, use the movement of the sewing thread to wipe off the excess oil stains, until there are no oil stains on the rags, and then proceed to the formal sewing.
The lubricating parts are: (1) Each oil hole on the machine head is used to lubricate the upper shaft and the parts connected to the upper shaft. (2) The components inside the panel and the movable parts connected to each component. Lubricate the presser foot bar, the needle bar and the parts connected to it. (3) Wipe clean the movable parts of the lower part of the machine board and add less oil.
