to thread. Hold the thread with both hands and slip into the appropriate guide from the right
side. Then gently pull towards the front, making sure the thread is firmly locked in the
pretension hooks.

⦁
At the end, re-thread the needle eyes and lower the presser foot.
Needles could be damaged

through the needle eyes.
