■Cause/remedy/check details

❏Cause 1

The machine is not correctly threaded.

<With symptoms 1 and 2 described above> The lower threading is incorrect.

Return the thread tension dial to “4”, and then refer to “Upper thread tightened up” (page 144) to correct the threading.

<With symptoms 3 through 5 described above> The upper threading is incorrect.

Return the thread tension dial to “4”, and then refer to “Tangled thread on wrong side of fabric” (page 145) to correct the upper threading.

❏Cause 2

A needle and thread appropriate for the fabric are not being used.

The sewing machine needle that should be used depends on the type of fabric sewn and the thread thickness.

If a needle and thread appropriate for the fabric are not being used, the thread tension will not be adjusted correctly, causing wrinkles in the fabric or skipped stitches.

•Refer to “Needle types and their uses” (page 38) to check that a needle and thread appropriate for the fabric are being used.

❏Cause 3

An appropriate setting on the thread tension dial is not selected.

Turn the thread tension dial to select an appropriate thread tension.

The appropriate thread tension differs according to the type of fabric and thread being used.

*Adjust the thread tension while test sewing on a piece of scrap fabric that is the same as that used in your project.

Note

zIf the upper threading and lower threading

are incorrect, the thread tension cannot be

adjusted correctly, even by turning the4 thread tension dial. Check the upper

threading and lower threading first, and then adjust the thread tension.

•When the lower thread is visible from the upper side of the fabric. Turn the thread tension dial to a lower number (toward the left). (Loosen the thread tension.)

•When the upper thread is visible from the lower side of the fabric. Turn the thread tension dial to a higher number (toward the right). (Tighten the thread tension.)
