2-/3-thread changeover attachment
Use the 2-/3-thread changeover attachment when it is desired
to carry out 2-needle overlocking, cover stitch (flatlock) or
2-thread hemming.
1. Turn off the power switch.
2. Press the 2-/3-thread changeover attachment mounted on
the upper looper to the left.
3. Check that the projection of the 2-/3-thread changeover
attachment is inserted into the hole in the top end of the
looper.
In the aforementioned state, the upper looper thread is not
fed. However, the lower looper thread is fed to form 2-thread
stitches.
