5-3. Threading the upper thread
A cAUTION
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.
[When using cotton thread and spun yarn]
(With synthetic thread)
(Threading
in
the upper thread breakage detector)
Real the thread from above once or
twice as the above figure.
• Thread the upper thread correctly as shown in the illustration above.
NOTE
10
• Turn the machine pulley and raise the thread take-up lever 0 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.
