FAQs & Troubleshooting

How do I thread the machine (Threading the upper thread)?

The machine is marked with numbers that indicate the threading order. Follow the numbers in order.
When threading the upper thread, carefully follow the instructions. If the upper hreading is not correct, the thread may become tangled or the needle may bend or break.
When using accessories not included with this machine, attach the accessory to the machine after threading the machine.
Never use the thread of No. 20 or lower.

Slide the spool cap onto the spool pin and return the spool pin to its original position.

When the presser foot lever is lowered
- When passing the thread behind the thread guide cover, be sure to use both hands. If you do not hold the thread with your right hand, the thread will be loose and you will not be able to secure the thread in the thread spring guide. It may cause incorrect thread tension.
- Make sure that the presser foot lever is raised before passing the thread behind the thread guide cover. If the presser foot lever is lowered, the thread guide spring is shut and you cannot hang the thread on the thread guide spring correctly.
Pass the thread through the guides in the order shown below.
Make sure that the thread is passed into the thread take-up lever as shown below.

Thread take-up lever

If the needle is not raised, you cannot pass the thread into the thread take-up lever. Be sure to press the needle position button to raise the needle before passing the thread into the thread take-up lever.
Pass the thread behind the needle bar thread guide.
The thread can easily be passed behind the needle bar thread guide by holding the thread in your left hand, then feeding the thread with your right hand, as shown.
