To Replace the Bobbin Case
After threading, take the bobbin case by the latch, holding
It between the thumb and forefinger of the left hand; place the
bobbin case on the centre stud of the bobbin case base, release
the latch and press the bobbin case back until the latch catches
the groove near the end of the stud. Allow the thread to hang
free and replace the slide In the bed of the machine.
To Set the Needle
Push the needle up In the needle bar as far as It will go,
with the long groove to the front, and secure It firmly with the
set screw.
It may be necessary to turn the needle slightly to the right
or left for some threads If stitches are missed.
Operators are liable to use needles which are too fine.
Better results usually follow the use of a needle of a larger
size.
Threading the Needle
(See Fig. 13)
Turn the machine pulley until the thread take-up (10) Is at
Its highest position.
Pass the thread from the unwinder, from back to front through
the lower hole (l) In the pin on top of the machine, from right
to left through the upper hole (2) In the pin, downward through
the hole (3), upward through the middle hole (4) and downward
through the hole (5) of the thread stralghtener, down and to the
left
between the tension discs (6), and against the pressure of
the controller spring Into the fork at (7), to the right of the
wire guard (8), up through the thread guide (9), from right to
left through the thread take-up eyelet (10), down again through
the guide (9), against the auxiliary thread take-up and back of
the guide (11), Into guide (12), down through the hole (13) at
the Icwer end of the needle bar, and from front to back through
the eye of the needle (14). Draw about two Inches of thread
through the eye of the needle with which to commence sewing.
Fig. 13. Threading the Needle
To Prepare for Sewing
With the left hand hold the end of the needle thread, leav­
ing It slack from the hand to the needle, turn the machine pul­
ley over toward you until the needle moves down and up again to
Its
highest point, thus catching the bobbin thread; draw up the
needle thread and the bobbin thread will come up with It throu^
the hole In the throat plate. Lay both threads back under the
presser foot.
To Commence Sewing
Place the material beneath the presser foot, lower the press­
er foot and commence to sew, turning the machine pulley over to­
ward you.
