03Step

Check in this order

  1. 01
    Step 1

    Switch off and confirm the correct needle is fully inserted with its flat side in the manual’s direction.

    Step 2

    Remove and reinstall the correct bobbin, following the case or drop-in threading guide.

  3. 03
    Step 3

    Thread the upper path with the presser foot raised and leave a 10–15 cm tail under the foot.

    Hold the upper tail gently and turn the handwheel one complete turn toward you, then pull the loop through.

What should restore normal sewing

The bobbin loop should rise through the needle-plate opening without force.

Place both tails behind the foot before the test seam.
