5-3. Threading the upper thread
■ Thread the upper thread correctly as shown in the illustration above.
NOTE
• Turn the machine pulley and raise the thread take-up lever q 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 and spun yarn]
Turn off the power switch before threading the thread, otherwise the machine may operate if the foot
switch is depressed by mistake and serious injury could result.
CAUTION
〈With synthetic thread〉
〈Threading in the upper thread breakage detector〉
Real the thread from above once or
twice as the above figure.
