4. PREPARATION BEFORE SEWING
4-1. Installing the needle
AcAur10N
A Turn off the power switch before installing the needle.
~
If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result.
1.
Loosen the set screw ( 1 ).
2.
Insert the needle (2) in a straight line
as
far
as it will go,
making sure that the long groove on the needle is at t
he
front, and then securely tighten the set screw ( 1
).
4-2. 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 t
hr
ead can be threaded more eas
il
y.
(Refer to following page.)
[If using cotton thread or spun thread]
[If using synthetic thread]
• 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 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 become tangled.
