1, to send the teeth to clean up: remove the needle plate and the teeth between the cloth, remove cloth, dust, and add a small amount of sewing machine oil.
2, the shuttle bed cleaning: shuttle bed is the core of the sewing machine work, but also the most prone to failure, therefore, regular removal of dirt and add a small amount of sewing machine oil.
3, other parts of the clean-up: the surface of the sewing machine and the various parts of the panel should always be cleaned and kept clean.
Sewing machine lubrication method of lubrication:
1, refueling parts: the head of the oil hole, lubricating the shaft and the shaft connected to the components; panel components and parts connected to the moving parts; lubrication of the presser bar and needle bar and its connected components; machine board The activities of the lower parts wipe and add less oil.
2, maintenance sewing machine should pay attention to matters: After the work is completed, the needle into the pinhole plate, lift the presser foot, but also cover the machine head with a machine to prevent intrusion of dust; start working, first check the main parts , Set foot on the severity of the situation, with or without special sounds, the needle is normal, and so on, if found abnormal, should be timely maintenance; machine use for a long time, to conduct a major overhaul, found that wear larger parts, To replace the new one.
Special sewing machine oil must be used. Continuous use of the sewing machine for a day or days should be a full plus oil, if used between the refueling, the machine should idle time, so that oil fully infiltration and thrown excess oil, and then a clean soft cloth head And the table clean, so as not to dirty the sewing material. Then thread sewing rags, wipe the use of sewing thread movement, throw off the excess traces of oil, until there is no traces of oil rags, and then formally sewing.
1, the nose of the oil hole, lubricating the shaft and the upper shaft connected components.
2, the panel internal components and components connected to the moving parts. Lubricate the presser bar and needle bar and their associated components.
3, the activities of the lower part of the machine board wipe clean and add less oil.
The refueling holes and refueling parts of the amount of refueling do not have too much, one or two drops on the line.
Second, the maintenance of sewing machines should also note the following:
1, the work is completed, the needle into the pinhole plate, lift the presser foot, but also cover the machine head machine to prevent dust intrusion.
2, start work, first check the main parts, how to set foot on the situation, with or without special sounds, the needle is normal, etc., if found abnormal, timely maintenance.
3, the machine after using for a long time, to conduct an overhaul, found that wear larger parts, to replace the new.
