5-13) NEEDLE-HOOK TIMING CONTROL
1) Needle
① It is very important to select the right needle for the type of thread and fabric used.
② Inappropriate needle may cause bad embroidery, thread breaks, skipped stitches, etc.
③ For normal embroidery, use a DB×K5 needle.
2) Relationship between Needle and Thread
① Inadequate selection of thread and needle may result in thread breaks, skipped stitches, as well as in bad-
quality embroidery.
② Refer to the following table of threads and needles used for normal embroidery.
3) Changing the Needle
① Make sure the needle is completely clear of the needle plate before attempting to change it. If the needle is not
clear of the plate, manually turn the main shaft with a hand lever to put the needle in the right location for
change.
[CAUTION]
Needle and thread most commonly used in embroidery are DB K5 #11 and rayon yarn 120d/2.
