5-3. Threading the upper thread
CAUTION
Turn off the power switch before threading the thread, otherwise the machine may operate of the foot switch is
depressed by mistake and serious injury could result.
■ 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.
