the use of sewing machine should be cleaned and lubricated frequently to ensure the normal operation of the machine

1. cleaning of sewing machine

(1) cleaning of cloth feeding teeth remove the screws between the needle plate and the cloth feeding teeth, remove cloth wool and dust, and add a small amount of oil in the experiment of sewing

(2) cleaning the shuttle bed. The shuttle bed is the core of the sewing machine, and it is also the most prone to failure. Therefore, it is necessary to often remove dirt and add a small amount of sewing oil

(3) cleaning of other parts. The surface of the sewing machine and all parts in the panel should be regularly checked for overload, overvoltage, overcurrent, overload, etc. of the measuring system and drive system

2. Special sewing oil must be used for lubricating the sewing machine. The sewing machine has been used for 4 consecutive days, and the national billet market has become stronger. After a few days or days, it should be fully oiled. If it is oiled before use, the machine should be idled for a period of time, so that the oil is fully soaked and the excess oil is thrown out, and then the machine head and table surface are wiped clean with a clean soft cloth to avoid soiling the sewing material. Then thread the rags, wipe them with the motion of the sewing thread, and throw out the excess oil stains until there is no oil stains on the rags, and then carry out formal sewing

the oiling parts are: (1) each oil hole on the machine head, lubricating the upper shaft and the parts connected with the upper shaft. (2) The components inside the panel and the movable components connected to each component. Lubricate the presser foot bar and needle bar as well as the components connected with them. (3) Clean the moving parts of the lower parts of the machine board and add less oil

there is no need to add too much oil to each oil hole and oil filling part, just one or two drops

2. When starting to work, first check the main parts, the weight of stepping, whether there is special sound, whether the needle is normal, etc. if abnormal phenomena are found, they should be repaired in time

3. The advantages of the process brought by the high precision and high reproducibility of the machine are more important. After a long time of use, an overhaul should be carried out. If parts with large wear are found, they should be replaced with new ones. (end)
