Threading the lowerlooper
Run the thread in the sequence illustrated, following the blue color and the numbers next to each threading point.
If the lowerlooper thread breaks during sewing, cut and remove thread from both of the needles.
Before re-threading the lowerlooper, make sure that the lowerlooper re-threading is done exactly as diagrammed above.
The machine will not operate properly if the threading is not done in the proper sequence.
(1) Lowerlooper
(2) Lowerlooper threading lever
When sliding the lowerlooper threading lever to the left, always make sure that the two pink triangular marks line up as illustrated.
Thread the needles after the lowerlooper and upperlooper have been threaded.
Slide the threading lever only in the directions shown by the arrow. Forcefully moving the threading lever in any other direction may damage it.
