Selection Of The Thread; Threading Of Needle Threads - Mitsubishi Electric LT2-2230-B1T Instruction Manual

HOW TO USE

3 Selection of the thread

It is recommended to use "S" twist thread in the left needle (viewed
from front), and "Z" twist thread in the right needle.
When discriminate use of needle threads is impossible, use "Z" twist
thread in both the needles.
For bobbin thread, "S" twist thread as well as "Z" twist thread can be
used.

4 Threading of needle threads

1 . Pass each needle thread through thread guide (A).
Note: When thin slippery thread (polyester thread or filament
thread, etc.) is used,
Pass the thread through thread guide (B) as well.
2 . With the thread take-up lever located at the upper most position,
pass each needle thread in the order shown in the following figure.
Note: Pushing the needle thread tension releasing button shown
in the figure below opens the saucer of the needle thread tension
adjuster, and the needle thread can easily pulled out.

Note: When needles
of small gauge (#11

needle thread should
be wound about 3/4
rotation around needles
and then passed
through needle eyes as
shown in the figure, to
assure neat stitches. It
is recommended to use
stepped needle.
