Maintenance

2) Remove dust from the needle plate, presser foot groove, and the area around the curved needle after work is completed.
(3) Wipe off the parts that are prone to rusting with an oiled cloth or the like.
4) Once a month, check whether the screws are loose.
5) Good or bad maintenance is related to the life of the machine and should be paid attention to.
