Before threading, turn off the machine for safety.
Threading steps are as follows.
-
Threading the looper
-
Threading the left needle
-
Threading the center needle
-
Threading the right needle
Threading the looper
Run the thread in the sequence illustrated, following the blue line and the numbers next to each threading point.
-
Open the front cover by sliding it to the right and guiding the top toward you.

-
Pull the thread off the spool and directly up through thread holder (1) and thread holder (2) on the thread tree, from back to front.

Threading the needles
About needle threads used by the various stitches:
When sewing a cover stitch on back side, thread the needles as follows.
-
The triple cover stitch (three-needle, four-thread cover stitch) uses the left needle thread, center needle thread and right needle thread.
-
The two-needle, three-thread cover stitch (Wide) ( 6 mm (15/64 inch)) uses the left needle thread and right needle thread.
-
The two-needle, three-thread cover stitch (Narrow) ( 3 mm (1/8 inch)) uses the center needle thread and right needle thread.
-
The chain stitch uses the center needle thread and looper thread.
When threading the needles, always thread in the following order: left needle, center needle and right needle.
1. Threading the left needle
Run the thread in the sequence illustrated, following the yellow numbers and
(yellow) marks next to the threading points.
-
Pull the thread off the spool and directly up through thread holder (1) and thread holder (2) on the thread tree, from back to front.
