Points to note when using an internal phone
When using the internal phone, you must pay attention to some basic precautions, so as to increase the operating safety factor. Therefore, when using this kind of equipment, manufacturers generally encourage consumers to read the instruction manual first, in order to increase consumers’ understanding of the equipment and some related precautions.
Needle characteristics and stitch types of two-thread seat type inner thread machine
1. When the internal line machine is in use, if it appears in an unmanned workplace, do not plug the power cord into the socket, and cut off the power when performing maintenance or cleaning.
2. When using the device, do not use it as a toy. Keep the device away from children to avoid harm to children.
3. In terms of replacement parts, only original parts can be used. Do not modify it yourself to avoid safety problems.
4. When operating the inner line machine, do not block any vents, and ensure that the vents and pedals of the sewing machine cannot accumulate any lint, wool, dust, etc.
5. Do not allow any objects to fall into the equipment opening.
6. Do not use the equipment outdoors.
7. When cutting off the power, do not drag the power cord, you should grab the power part and pull it out.
8. When using the internal line machine, pay attention to protect your fingers, and be careful in the operation.
9. When using this equipment, use the original needle plate to avoid broken needle problems affecting the progress.
10. Do not push or pull the fabric vigorously during use, so as to prevent the stitches from bending or breaking.
11. During routine operations such as threading and needle replacement, pay attention to whether the power is off.
Faults and troubleshooting of the internal machine
In the long-term use of the internal machine, a series of problems will occur due to the durability of the equipment. These problems are very normal and can be solved with a little adjustment. So how should we adjust and maintain these internal machine failures?
The internal line machine is disconnected. I believe that most users will have this situation when using this product. This situation means that the horn seat of the internal line machine is loose, because the pinhole of the horn cover is worn out, so just replace the horn cover. Okay. Another situation is that the mouth of the horn mouth with the reel is increased due to wear and tear. This problem can be solved by replacing the horn mouth with a new one. Another point to be concerned about here is the needle problem, that is, the wear of the needle shaft will cause the needle to not be able to be positioned correctly. Generally speaking, the rotation center of the needle, the horn cover and the horn of the individual parts are not concentric. If the above situation occurs, the concentricity of the three parts needs to be adjusted to make it fit smoothly.
Needle characteristics and stitch types of two-thread seat type inner thread machine
The coil of the inner line machine is disconnected. This situation is caused because the needle is not installed correctly, and the thread tension is too large. This situation can be caused by adjusting the tensioner, or replacing the needle hook, and checking whether the pressure spring is stuck. A good solution to this problem.
The needle code of the inner thread machine is missing. This situation basically occurs because the winding operation is not good, and sometimes the phenomenon of stagnation occurs. At this time, check whether the winding wheel or the needle bar can be jammed by foreign objects. If not, check the vertical Whether the coupling on the drive shaft is slipping due to insufficient friction, increase its pressure if necessary. The second is that the position of the winding wheel is wrong. At this time, the needle shaft can be at the upper limit position, loosen the screws of the horn cover and the horn mouth, take out the winding wheel and gear rod to reinstall and adjust. When installing, the thread hole of the winding wheel must be at the right end of the needle shaft. After installation, the thread hooking effect can be manually adjusted. If necessary, the winding wheel can be rotated forward or backward by one tooth.
