How do you bring the bobbin thread up in the JUKI buttonhole machine?

How do you bring the bobbin thread up in juki button hole machine

Not only you can sew but bring the bobbing thread up in your JUKI buttonhole machine by following these steps:

Step 1

  • Start by ensuring that the take-up lever of your sewing machine is in the highest position. This is important for proper thread tension and to avoid any issues or jams.
  • Roll the hand wheel towards you, following the arrow on it. Beginners often make the mistake of pushing it away, which can cause problems.
  • Roll the wheel towards you until the take-up lever reaches the highest position possible.

Step 2

  • Once the take-up lever is in the highest position, take your thread and pull it underneath the presser foot towards the back.
  • Pull the thread for about five inches and note the tension. It should feel a little tight but not overly loose or too tight.
  • If the thread feels too loose, it may not be properly inserted into the tension mechanism. Adjust it if necessary.

Step 3

  • Practice pulling the thread to become familiar with good tension and bad tension. This will help you determine if your machine is threaded correctly before starting to sew.
  • Good tension allows the thread to move smoothly, while bad tension may cause the thread to get stuck or break.
  • Pull the thread to test the tension and get a feel for what is right.

Step 4

  • Note that if the take-up lever is down, the thread will be locked and won’t come through.
  • To test the thread tension, ensure that the take-up lever is up. If you pull the thread and it doesn’t come through, the tension is too tight.
  • Avoid pulling the threads towards you, as this can bend the needle. Always put the thread underneath the presser foot, resting against it rather than the needle.

Step 5

  • To pull up the bobbin thread, make sure your machine is threaded correctly, and the take-up lever is in the highest position.
  • Hold the thread with a little tension and turn the hand wheel towards you to take one stitch.
  • One stitch occurs when the take-up lever completes one full rotation, moving down and then back up.

Step 6

  • Avoid the misconception that one stitch means the needle goes down and comes back up. This is actually only half a stitch.
  • To pull up the bobbin thread, you need to turn the hand wheel until the take-up lever reaches the top position.
  • Ensure the take-up lever is at the highest point for successful thread retrieval.

Step 7

  • Keep turning the hand wheel until the take-up lever is all the way up.
  • It’s essential not to rush this step. Make sure the take-up lever is at the topmost position before proceeding.

Step 8

  • Pull the thread gently and look for a loop that pops up.
  • The loop may be small, but it’s the indicator that the bobbin thread is coming up.
  • Continue pulling the loop until you find the end of the loop, which consists of two full threads representing the bobbin thread.

Step 9

  • Take both threads (the top thread and the pulled-up bobbin thread) and put them underneath the presser foot, pulling them towards the back.
  • Ensure the threads are positioned correctly to allow sewing on both the top and bottom sides of the fabric.

Step 10

  • Before starting to sew, remember to lower the presser foot.
  • If the presser foot is still up, lower it using the lever located at the back of the machine or any other appropriate mechanism your Juki sewing machine might have.

Step 11

  • Now you’re ready to insert your fabric and begin sewing with the correctly pulled-up bobbin thread and properly positioned top thread.
  • Always double-check that the presser foot is down before you start sewing to avoid jams and ensure smooth stitching.
