1. Standby: Use the four fingers of your right hand to support the machine base, and place your thumb naturally on the top of the machine cover. Hold the entire machine smoothly. 2. Thread Passage: Gently pull the thread from the spool one through the guide coil A, then lead it into the thread clamping adjustment piece B, and then through the guide coil C. The thread head that has been led through is temporarily placed next to the machine needle. Also, lead the thread guide through the needle hole in front of the machine needle towards the junction of the machine body, and then lead the thread head into the small hole of the thread guide. Exit the thread guide and pull the thread head out 23 cm to press it with the threading plate and use it as needed. 3. Fabric placement: Lift the press plate with the index finger of your right hand, and place the prepared fabric to be sewn flatly under the press plate, and gently return the press plate to press the fabric. 4. Sewing operation: Use your left hand to hold the fabric, and press the top of the cover with your right thumb gently and quickly to the bottom, then raise your thumb and press down again. Repeat this, and the feeding mechanism will automatically move the sewn item to the left. Hold the machine with your right hand and gradually move to the right, and the left hand holds the fabric to move the sewn item gently to the left with the sewing rhythm until the sewing is completed. After cutting the thread on the press plate, lift the press plate, and gently pull out the fabric to tighten it. (Note: Because this machine uses only one spool, the thread under the press plate does not need to be cut, just pull it out, or it cannot be tightened.) 5.This function can automatically feed the fabric and adjust the tension between the stitches. If you need to change to a larger spool, you can connect the spare extension rod to the spool shaft, insert the larger spool, and then re-thread the needle. After adjusting the tension of the thread, proceed with the sewing. 7. Change the needle: Loosen the fixed screw, remove the broken needle, install the new needle, and ensure that the smooth side of the needle is aligned with the fixed screw. Do not install it backwards. The needle type is DHX14.
