Threading the Upper Thread

EN
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. 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 as shown. 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
and up left channel. (5) During this process it is helpful to hold
the thread between the spool and thread guide.
- 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 thread behind the thin wire needle clamp guide (7)
and then down to the needle which should be threaded from
front to back. (See page 19 for instructions on how to use the
Automatic needle threader.)
- Pull about 6-8 inches of thread to the rear beyond the needle
eye. Trim thread to length with built in thread cutter.
