If the sewing machine sews materials for a long time, it may cause the problem of skipped stitches or skipped threads during the operation of the machine, and the sewing effect will be flawed. In order to make the sewing effect beautiful and neat, we must maintain the machine well, so we are required to choose special sewing machine oil and refuel it once a week.
In addition, if you refuel before use, you should let the machine idle for a while to allow the oil to fully penetrate and shake out the excess oil, and then wipe the machine head and table with a clean soft cloth to avoid dirtying the sewing material. Then thread the sewing thread to sew the scraps of cloth, use the movement of the sewing thread to wipe it clean, and shake out the excess oil until there is no oil stain on the scraps of cloth, and then start formal sewing.
