5-3. Threading the upper thread
CAUTION
If the power switch needs to be left on when carrying out threading, be extremely cafeful to observe all safety
precautions.
The machine may operate if the foot switch is depressed by mistake, which could result in injury.
(ex. Continuing sewing from a stopping point)
Thread the upper thread correctly as shown in the illustration above.
Note
Turn the machine pulley and raise the thread take-up lever (1) 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 40 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.
[When using cotton thread] [When using the liquid cooling tank]
