Threading The Lower Thread (Looper Thread) - JUKI MEB-3810N Series Instruction Manual

(2) Threading the lower thread (looper thread)

For the model provided with the
needle thread clamp unit
1. When passing the looper thread, turn looper bracket by 180 degrees of an angle in advance.
2. In the case of the overall thread trimmer type machine, pass the looper thread through the needle
hole in the throat plate and allow the looper thread clamp to clamp it. Then, start sewing.
In the case of the needle thread trimmer type machine, allow the thread trimmer retaining plate
to clamp the looper thread and gimp. Then, start sewing.
If thread waste is clamped by the looper thread clamp or the thread trimmer retaining plate, remove
it. If sewing is carried out when the thread waste remains clamped by either of them, the looper
thread cannot be clamped properly, resulting in stitch skipping at the beginning of sewing.
