5-3. Threading the upper thread
Thread the upper thread correctly as shown in the illustration below.
* When using threading mode for threading, the tension discs (1) will open so that the thread can be threaded more easily.
(Refer to following page.)
• Turn the machine pulley (2) and raise the thread take-up (3) to its highest position before threading the upper thread.
(This will make threading easier and it will prevent the thread from coming out at the sewing start.)
• When threading the thread through the needle, allow a distance of approximately 42 mm between the needle hole and the
end of the thread.
If the trailing length of the thread is too long, it may cause the thread to become tangled.
