Pull up on the thread spool pin to lengthen the height. Place the thread spool on the pin
and pass the thread around the bobbin winder pre-tension disc.
Pass the thread through the hole
on the bobbin from inside. Use
upper hole, not both. Place on
bobbin shaft and slide to the right.
While holding the end of the thread,
press the foot controller to begin
winding the thread. Cut the thread
from the top and proceed winding. When the bobbin starts to spin
slowly and becomes full, release
the foot controller. Cut the thread,
slide the bobbin winding shaft to
the left and remove the bobbin.
Raise the needle to its highest position and
remove the bobbin case by pulling the latch.
Hold the bobbin case as shown. Insert the
bobbin with the thread coming from the bottom
toward the top and the thread tail hanging out of
the bobbin case.
Pull the trailing thread through the
slot, down and to the left, until it
enters the delivery eye under the
tension spring. CAUTION: Make
sure you set the bobbin so the thread
unrolls in the right direction. If the
thread unrolls in the wrong direction,
it may cause the thread tension to be
incorrect or break the needle. Holding the bobbin case by the latch,
align your fi nger with the top opening
of the shuttle race, insert the case
into the shuttle race and release the
latch.

Threading the Needle
Raise the thread take-up lever to
its highest position by turning the
handwheel. Place the thread spool on the
spool pin.
(Don’t forget to pull up the pin) Pass the thread through the thread guide and down the
right channel on the front of the machine.
Pass the thread into the thread tension discs or behind the
thread tension dial from the right to the left. Grasp the thread on both sides of the tension disc and pull to
ensure it is in place.
Guide the thread up the left channel, clear to the back of the opening around
the take-up lever and back down the left side of the channel to thread the
take-up lever. Thread the needle from front to back and pull
out about 5 cm (2 inches) of thread.
