Threading the Upper Thread

This is a simple operation but it is important to carry out correctly as
by not doing so several sewing problems could result
- Start by raising the needle to its highest point (1), and continue
turning the handwheel* counterclockwise until the needle just
slightly begins to descend. You must raise the presser foot to
release the tension discs.
Note: For safety, it is strongly suggested you turn off the power
before threading.
- Lift up the spool pin. Place the spool of thread on the holder with
the thread coming off the spool from the back as shown and
place appropriate spool holder next to the spool. For small
thread spools, place small side of spool holder next to spool. (2)
- Draw thread from spool through the upper thread guide (3) and
pulling thread through pre-tension spring as illustrated. (4)
- Thread tension module by leading thread down right channel. (5)
During this process it is helpful to hold the thread between the
spool and thread guide, as this will help to seat the thread
between the tension discs.
- At the top of this movement pass thread from right to left through
the slotted eye of the take-up lever and then downwards again.
(6)
- Now pass the thread behind the horizontal thread guide, and
then behind the thin wire needle clamp guide (7) and then down
to the needle which should be threaded from front to back.
- Pull about 6 - 8 inches of thread under the presser foot to the rear
beyond the needle eye. Trim thread to length with built-in thread
cutter. (8)
* Never turn the handwheel away from you as this may cause the
timing to be disrupted. Always turn the handwheel
counterclockwise (towards you).
