Lubricating
Special sewing oil must be used. The sewing machine should be fully oiled after one or several days of continuous use. If oil is added between uses, the machine should be idling for a period of time to fully infiltrate the oil and throw off excess oil. Then use a clean soft cloth to clean the machine head. Clean the surface and the countertop to avoid soiling the sewing material. Then thread and sew the rags, use the movement of the sewing thread to clean them, and throw off the excess oil stains until there is no oil stains on the rags, and then proceed to formal sewing.
