Starting up
Before you start putting the thread into your Juki sewing machine, you should always make sure that the machine is powered off and unplugged from the mains. Once the machine is powered off, raise the presser foot lifter until the needle plate is level with the presser foot. Then, open the side cover, where the thread is usually stored, and get the upper and lower threading spools out of their spools holders. Take care with the wound thread as it can get tangled very easily, so it’s better to handle and move it carefully.
Now that you have your threads ready, you should prepare the machine for threading. Put the bobbin into its bobbin case, making sure you don’t let any of the threads come out of the case, and place the battery into the battery holder securely. Move the bobbin thread into the bobbin case and make sure it is properly seated and secured. If necessary, gently pull the bobbin thread and the threads should be pulled up to the upper side of the needle plate.
Upper Threading
When the bobbin is correctly threaded and seated, the machine is ready for the upper threading. The first step is to rise the presser foot and lift the needle to its highest position. You should then pass the upper thread through the first thread guide, located beneath the spool holder. Move the thread counterclockwise to pass the thread from the back of the machine to the front and pass the thread through the second thread guide. Now, take the thread to the take up lever and move the thread around the take up lever in a clockwise motion to ensure the thread is securely placed. Then, take the thread down to the needle threader and guide the thread through the needle from left to right. Once the thread is threaded through the needle, you should pull the thread until it reaches the bobbin thread at the back of the machine.
Lower Threading
Before a lower thread can be put into the sewing machine, the thread needs to be passed through the eye of the bobbin. To do this, put the bobbin threaded side down into the bobbin case, making sure to keep the thread on the inside of the bobbin. Pull the thread up to the top of the machine and thread the bobbin by guiding it through the upper thread guide. Take the thread to the tension wheel and make sure the bobbin is properly secured in the bobbin case.
Once the bobbin is secure, you should make sure that the top of the bobbin catches onto the hook, at the base of the needle plate. You then need to gently pull the thread down to the front of the machine, beside the thread take-up lever. Pull the bobbin thread until it reaches the thread take-up lever and then pull the thread to the right, ensuring that it is securely placed in the take-up lever groove.
Starting to Sew
Once the thread is in the Juki sewing machine, close the side cover and lower the presser foot lifter until the presser foot is raised. Now, with the upper thread and lower thread pulled to the front of the machine, push down on the needle/hand wheel and hold the upper thread and the bobbin thread so that the two threads are caught in-between the needle plate and the presser foot. Then, wrap the two threads around each other, ensuring that the thread is secure. Finally, release the needle/hand wheel and switch the power on. Press the foot pedal on the machine and with both threads secured, the machine is now ready to start and the machine should start to sew without any problems.
Troubleshooting
If the machine is still not sewing correctly, then it is possible that the thread needs to be re-threaded. Before re-threading the machine, make sure that the threads are correctly placed and that both the upper and lower threads are pulled to the front. After this, follow the steps above once again, and if that still doesn’t work, then you should consider contacting a professional sewing machine technician who will be able to help you diagnose and fix your machine.
Tips & Advice
When it comes to threading a Juki sewing machine, one of the main problems that people encounter is dealing with the tangled threads. To ensure that the threads don’t tangle, first use a thread coil stringing tool, which can help guide the thread from the spool holder to the needles. When dealing with the bobbin thread, move it from the back of the machine to the front and follow the step-by-step instructions outlined above. Finally, do not forget to attach the end of the thread to the eye of the bobbin when the correct threading technique is used. This can save a lot of time, hassle and hassle.
Advanced Techniques
Once you master the basic method of threading a Juki sewing machine, you can explore a wealth of options to help you sew professional quality and consistent stitches. Firstly, you can experiment with different types of thread and threads of different thicknesses and sizes in order to achieve different results. Additionally, you can even try using thicker threads or combining different colors of threads in order to create unique and eye catching designs. Furthermore, you can use special tools such as a needle threader – a convenient tool which can help in threading the needle quickly and easily.
Safety Measures
Taking the correct safety measures when sewing on a Juki sewing machine can help to prevent injuries. Firstly, make sure to invest in a good pair of scissors as scissors can easily damage the fabric as well as the machine itself. Additionally, be sure to wear safety goggles and maintain the machine by replacing the needle after every two to three uses. Additionally, make sure to read the instruction manual before starting any project and always unplug the machine before adjusting the settings. Finally, remember to check the tension on the thread and make sure to use the correct bobbin sleeve for your particular machine.
Maintenance Tips
Maintaining a Juki sewing machine is essential in order to keep it in good working condition and prevent any potential problems. Firstly, make sure to clean the machine regularly, paying special attention to the needle, bobbin case, and presser foot. Additionally, lubricate the machine parts with sewing machine oil every six months, or when signs of wear and tear start appearing. Finally, don’t forget to replace the needle after every two or three uses and if you encounter any issues, then seek help from a professional technician.
