Firstly, the needles of the sewing machine are selected according to the thickness of the fabric to be sewn (the number of needles is 1, 2, 3). Generally choose No.2 or No.3 to use. Then install the needle, loosen the needle mounting screw, put the needle vertically into the needle slot from below, and then tighten the screw. Be careful not to put the needle upside down.

According to the stitch size you need to sew clothes, you need to adjust the position first. Generally choose between 7 and 8. Loosen the position screw first, and then adjust the position up and down. After adjustment, tighten the screws. Prepare the bobbin thread, that is, thread the bobbin thread on the machine bobbin with lock core, and then press the button around the bobbin thread. Then loosen the pulley and the nose part and use the pedal to wind the thread (just like a sewing machine). Don't choose to thread at this time.

After the bottom thread is wound, the left hand takes out the lock cylinder sleeve with the lock cylinder from under the needle of the sewing machine board, installs the wound lock cylinder thread, and pulls the thread end out of the lock hole. Put the lock sleeve with lock core back to its original position, and install the back cover pressure plate.

Then install the thread, pull the thread head, and carefully thread the thread step by step along the logo of the machine. After putting it on, check it again carefully to see if it is correct. Pass the line through the pinhole after it is correct. Pull the thread with your left hand, turn the right wheel with your right hand, turn the needle to the bottom and then lift it, and the bottom line will be pulled out.

Put the upper and lower lines back. Then put the cloth to be sewn in the middle of the pressure plate, remove the presser foot and press the cloth. At this point, everything is ready, start turning the handwheel, and at the same time step on the machine pedal, and the cloth will go back. Just hold the direction of the cloth with your hands.
