How do excellent technicians repair sewing machines

First of all, we should ask the lathe worker what are the faults of the machine, such as needle skipping, thread breaking, thread throwing, etc. we will deal with the symptoms and solve the problems.

Look, see the stitching effect, whether the bottom thread is good-looking, and the flatness of the fabric, and judge the problem.

Listen, when there is an abnormal sound when the machine works, for example, there is a lot of noise at the front and lower part of the head when the flat sewing machine steps on, we can find the source of the sound, and we can specifically judge that the shuttle bed is short of oil, the lubrication is not enough to produce noise, the shuttle bed has been used for too long, it should be replaced, and the positioning interval between the shuttle bed and the needle has not been adjusted... In this way, the problem can be solved quickly.

Smell. Generally, when the motor is burned or the electronic components of the circuit board are burned, there is a peculiar smell, and the problem can be found quickly.
