.
Place thread on Telescoping Spool Pin.
Draw thread through Rear Thread Guide
and Bobbin Winder Tension Disc as
indicated.
Pull end of thread through any hole in
bobbin; place bobbin on Bobbin Winder
Shaft with end of thread coming from top
of bobbin as shown above.
3. Push Bobbin Winder Latch against bobbin
until it clicks. Then pull Hand Wheel away
from machine to disengage clutch (see
diagram below). Hold end of thread
coming from bobbin (see above) and step
on foot control. After several rotations of
bobbin release thread.
4. When bobbin is full, winding stops
automatically. Push in Hand Wheel.
Remove bobbin from shaft and trim
thread end.
* Treat Hand Wheel as a "clutch"
It controls the needle mechanism so that
when pulled out (disengaged), the rest of
the machine will not operate while the
bobbin is being wound.
For best stitching results use clear plastic
lightweight bobbins when stitching at high
speed with widest and longest stitch
setting.
