  11. Check the condition of the needle, and then install it.
    If the needle is in a poor condition, for example, if it is bent, be sure to install a new needle.

    Before using the needle, place the flat side of the needle on a flat surface and check that the distance between the needle and the flat surface is even.

    If the distance between the needle and the flat surface is not even, the needle is bent. Do not use a bent needle.

    (1) Flat surface

    Do not use a bent needle. Sewing with a bent needle is extremely dangerous since the needle may break while the machine is being operated.

     

Checking machine operations

If the needle plate has been removed, check machine operations to confirm that installation has been completed correctly.

 

  1. Turn on the machine.

     

  2. Select imageStraight stitch (middle or center needle position).

    Do not yet install the presser foot and thread.

  4. Select image (zigzag stitch) . At this time, increase the stitch length and width to their maximum settings.

     

  5. Slowly turn the handwheel toward you (counterclockwise) and check that the needle bar and feed dogs operate correctly.
    If the needle or feed dogs contact the needle plate, the machine may be malfunctioning; therefore, contact your nearest authorized service center.

     

  6. Turn off the machine, and then install the presser foot holder and presser foot. 
    Refer to How do I remove or attach the presser foot holder? and How do I remove or attach the presser foot?

     

  7. Install the bobbin.
    Refer to How do I install the bobbin wound with thread?

     

  8. Correctly thread the machine.
    Refer to How do I thread my machine?

    The thread may have become tangled as a result of incorrect upper threading. Make sure that the machine is correctly threaded.

     

  9. Perform trial sewing with normal fabric.

    Incorrect sewing may be the result of incorrect upper threading or sewing thin fabrics. If there are poor results from the trial sewing, check the upper threading or the type of fabric being used.
