Threading the Machine
1.
Place thread on spool pin, pass the thread
through the thread-mast eyelet from back to front,
continuing to
thread guide
A
.
2.
Continue to three-hole
thread guide
B
.
Wrap all three holes from back to front, handwheel
side to needle side (
Detail 1
) being careful not
to cross threads. This is recommended for most
threads. However, some very delicate threads or
metallic threads may require less tension. If you
are having breakage problems, try threading only
one or two holes.
3.
Thread continues through
thread guide
C
,
and then down to the
tension assembly
(
Detail 2
).
NOTE:
It is important that the thread is
“flossed” up between the two tension discs.
If the thread is not firmly in place between
the two tension discs, the thread rests on top
of the tension discs and looping can occur.
Diagram F
NOTE:
The purpose of this guide is to prevent
loops of thread coming off of the thread cone
and going into the top tension as a knot,
causing thread breakage and bad tension.
For most threads on a cone, it is important to
thread all three holes for consistent results—
should top thread tension need to be adjusted
it should be done at the top tension assembly.
