4. PREPARATION BEFORE SEWING
4-1. Installing the needle
CAUTION
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 the
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 thread can be threaded more easily.
(Refer to following page.)
• 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.
Use the optional needle cooler unit.
