4.
Pull the long extending blade all the way out
and back in again, ensuring it slides smoothly.
Clean the thread cutter of lint and debris on
both the top and underside of the cutter. Put a
small drop of oil on the underside of the long
extending blade.
If the long extending blade continues to jam or
not slide smoothly, loosen the small Phillips
screw that holds the setting plate in place and
move the plate so it is as close to the long
blade as possible without it touching.
5.
If the thread cutter has trouble cutting, such
as not cutting the top or bobbin thread or the
thread is cutting too short or too long, loosen
the small Phillips screw that holds the small
cutting blade in place. If you pivot the blade
towards the back of the machine, it will cut the
thread longer. If you pivot the blade toward the
front of the machine, it will cut the thread
shorter.
Note that these are very fine
adjustments.
6.
Be sure to thoroughly clean any thread and
lint from the step motor gears. Also check for
any broken or chipped teeth on the gears. Put
a small amount of white lithium grease on the
gears to help the cutter run smoother and
quieter.
