1, Release clutch by turning clutch knob
toward you,
2, Draw thread from spool through
bobbin winder tension discs as shown,
3, Putt end of thread through hole in

4. Place bobbin onto bobbin winder shaft
with end of thread coming from the top
of the bobbin, Push bobbin winder
latch against bobbin until it clicks_
Holding onto end of lhread, t_lar_
machine. When bobbin is siighttv fil_ed,
snip off end of thread.
5, Start machine. Wind thread until
bobbin winder latch releases,
6, Tighten clutch knob and remove
bobbin,
Two spool pins have been included with
"this machine to aid in bobbin winding. By
placing a spool of thread on the second
spool pin, you may wind your bobbin
witt_out unthreading the machine°
1, Insert bobbin into bobbin case
making sure thread is coming from
bobbin as shown,
2, Pull thread through slot of case as
shown,
3. Pull thread under tension spring.
4. Turn hand wheel to raise needle to
5_
its highest position, Holding latch
open, position case into shuttle, and
release latch, Case should lock into
place when latch is released,

1, Place thread on spool pin as shown,
with the threading coming from the
back of the spool (Fig. 1.-a). Draw
thread through the rear thread guide
(Fig. 1.b, !-c)0 Pass thread through top
thread guide (Fig. led),
2. Holding the spool with the right hand.
pull the thread through tile tension
discs. The spring wire loop should be
pulled up until the thread passes
beyond the beak bf 1he hook. Fig. 2.

4. Cor!tinue threading through the front
thread guide, hook thread into take up
lever and down through path _shown in
Fig, 4 and 5,

shewn iT_Fig. 5,
Probably the most important control on,your machine is this one that regulates your
top thread tension, It consists of discs between which the thread passes. The
pressure on these discs is regulated by _urning the dial. The higher the number, the
tighter the tension,
There are many reasOns for having to reset your tension. The best tension for one
fabric may not be correct for another. The required tension depends upon the
stiffness of the fabric, thickness of the fabric, numbers of layers of fabric being
sewn, as well as the type of stitch you are making.
It is best to test the stitching on a scrap of the fabric you are using before starting to
make a garment as shown below. Use the straight stitch function.
Upper thread too tight
Decrease Tension
Upper thread too loose
increase Tension
!
Bobbin tension requires adjusting less frequently than the upper thread tension,
If the stitch is satisfactory but the seam is puckered, it may be necessary to loosen
Lhe tension on both the top and bottom threads. Be sure to balance them as
!ndicated on page 10,
When adjusting the tension on the bobbin case, make slight adjustments with a
_rewdriver+ Correct tensions will produce the stitch shown on page 10.
Turn Clockwise,
Theeasiestway to check tensions isto sew a medium zig zag stitch on the fabric you
will be using. Use the appropriate type of thread and needle, Use different colors of
thread on the bobbin and upper spool,
Sew a line of zig zag stitches. The bobbin thread should not show on the top of the
fabric,
Adjust the top tension if necessary to achieve the stitch balance as shown below,
