push down inner pin until suitable pressure
is obtained.
Insufficient pressure may cause poor
feeding of the fabric, skipped stitches, or
difficulty in guiding the fabric. If feed dogs
or presser foot marks appear on the fabric,
reduce the pressure.
When sewing multiple thickness or heavy
fabric, reduce the pressure. Increase
pressure when sewing lighter weight
fabrics.

4. STARTING TO SEW
Now that you are familiar with
the controls on your machine and
with the accessories
provided for the machine, you are
ready to start to sew with your
new sewing machine.
Below are some good habits to follo
w each time you sit down to
sew:
1. Test the needle: it should be strai
ght, properly set and sharp on
the point. It should be
the correct size for the fabric and
thread being used. Do not be
afraid to change your
needle frequently. Many of the
new fabrics made of synthetic blen
ds tend to dull the
needles more easily than fabrics
made of natural fibers.
2. Before placing the material on
the machine, see that the ends of
the threads have been
drawn about 6 inches to the rear
of the machine. Hold on to threa
ds during the sewing
of the first 3 or 4 stitches of the
seam.
3. Test the machine stitch on a scrap
of fabric you plan to use. The fabri
c should be double
thickness. Adjust the machine for
the length of stitch and tension
suitable to your fabric.
4. Fabric should be placed under
the presser foot with the bulk of
the material to the left
of the needle and the right edge
of the material placed on the appr
opriate seam marking
for desired seam edge.
5. Run the machine at a slow oven
speed. The more pressure you put
on the foot control,
the faster the machine will sew.
6. Fasten each seam by back tacki
ng at the beginning and end of
the seam.
7. Always finish sewing each seam with
the needle at its highest point.
8. Guide the fabric gently with
your hand in front of the needle.
Never pull or hold the
fabric in such a way that the
normal feeding is altered.
9. When turning the hand whee
l manually, always turn it towa
rd you.
Turning A Square Corner
To turn a square corner 5/8
”
from the fabric edge, stop
stitching with the needle tip
piercing the fabric, when reaching
the cornering guide as shown,
Raise the presser foot, turn
fabric. New stitching line will
align with 5/8” seam guide on
side of needle plate. Lower the
presser foot and begin stitching
in new direction.
—17—
Pattern Selection Dial
The desired stitch will be obtained by turning the stitch selector, it
can be
turned either to the right or to the left.
Note: When operating selector, make sure needle is in the highest positio
n.

Cloth Guide
*
Option accessory.
Use cloth guide when sewing a
long seam of regular distance
from edge of material.
Set guide in hole on arm, at right
of needle plate, and adjust
distance.
Run machine with edge of fabric
touching guide.
Position cloth guide at an angle
to sew a curved seam.
Sew reverse stitches for rein
forcement at end of seam.
Draw fabric to left when sewing
is finished.
Cut threads with thread cutter
behind presser bar.
Adjusting Thread Tension
Test stitch performance on a
scrap of material you are going
to use.
With correct tension (®). upper
and lower threads tension is
equal and strong enough to lock
both threads in center.
If upper tension is too tight
(loose), upper (lower) thread lies
straight along
upper (lower)
surface of fabric (6J©). Correct
by turning tension dial.

Adjusting Stretch
Stitch Balance
In stretch stitch sewing, the
stretch stitch adjuster should
usually be in a neutral position
(between ‘+‘ and “—“). When
sewing some fabrics, you may
need to adjust this control to
balance the stitches for appear
ance sake.
If design seems open like the
illustriations to the left, adjust the
control slightly toward

design looks like the center
design.
If the design appears to be closed
as in the right hand illustrations,
turn the control toward “+“until
