Household electric sewing machine should be used for maintenance

The main points of use of multi-function sewing machines are very different from those of old-fashioned sewing machines. Beginners need to have a process of running into the machine. According to reports, just start using the sewing machine to start from the threading and sewing straight line, to understand the speed of the foot and pedal. After straight line proficiency, practice the needle down, stitch the pattern, and finally the seam. If you try a difficult operation as soon as you come up, it is easy to break the needle and disconnect the wire.

Do not ignore the daily maintenance of the sewing machine. The correct use is good maintenance. Secondly, when the pressure foot is lowered, the needle should not be left empty. In addition, the bottom shuttle position should be cleaned in time. The dirt is very worn on the machine. After cleaning, the two drops of oil are kept lubricated. The needle bar part of the machine head should be regularly refueled.

In the normal use of the process, jumpers, broken needles, etc. can often be detected by themselves, and small problems can be solved by themselves.

Jumper: First of all, improper use will cause the needle to bend, which will cause jumper. At this time, the needle can be changed. If the needle bar is moved up, it may lead to jumper. It is best to ask the professional to repair it. Sewing elastic fabric may also cause Jumper, change the special elastic needle at this time, or cover the fabric under the fabric, and tear off the newspaper after sewing.

Broken needle: When the pattern is changed, the needle will swing. If the needle is not lifted and is on the cloth, it is easy to cause needle breakage and disconnection. If the needle quality is unqualified, the needle will also be broken and replaced directly.

Wrapped line: This is caused by the upper line being too loose. First, you should use the upper thread adjustment knob to tighten the upper thread, and also check if the thread enters the clamping thread when threading. (Li Yanjing)
