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.

Refer to the following table of threads and needles used for normal embroidery.
3) Changing the Needle

Make sure the needle is completely clear of the needle plate before changing 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.
