bed. Push cloth plate to right until it snaps in locked position.
See pages 81 to 86 for applications of cylinder bed feature.
NEEDLE AND THREAD SELECTION
The selection of thread should be based on the fabric to be stitched. The thread should blend with
the fabric in colour, fibre and size.
Silk and wool fabrics should be stitched with silk thread; cotton fabrics should be stitched with cotton
or cotton mercerised thread, etc. The thread must be of a size that will imbed itself into the texture of the
fabric. Thread that is too heavy for the fabric will remain on the surface and become weakened by
friction and abrasion.
The selection of the needle should be based on both the fabric and thread being used. The eye of the
needle must be large enough for the thread to pass freely through it. The blade of the needle must be fine
enough not to mar the fabric with too large a puncture, yet heavy enough to pierce the fabric without
binding or deflecting.
You will obtain best stitching results from your Sewing Machine if it is fitted with a SINGERS' Needle.
NEEDLES AND THREAD
This machine uses needles
Catalogue 2020 (15X1).
Sizes 9, 11, 14, 16 and 18.
For perfect stitching, select correct needle
and thread to correspond with fabric (see
page 6).
Be sure to use similar threads for both
needle and bobbin.

on spool pin and lead through threading points
shown. Thread needle from front to back. Draw
sufficient thread through eye of needle with which
to start sewing.

Numerals on left side of indicator represent
number of stitches per inch.
Numerals on right side represent stitch length in
millimeters.
The upper indented area of the indicator repre
sents stitch lengths above 20.
The lower indented area of the indicator allows
the No. 6 stitch length setting to be "locked" in
place when stitching folds, pleats or multiple layers
of heavy fabric.
To set stitch length
• Release pointer by turning thumb nut to the
left.
• Position lever for desired stitch length.
/
• Tighten pointer against plate by turning thumb
nut to the right.
Once the pointer has been positioned, reverse
stitching is accomplished by raising the lever to its
highest position. The No. 6 "locked" position must
be unlocked for reverse stitching.
15
STITCH WIDTH AND NEEDLE POSITION SELECTOR
A Stitch width or needle position setting is necessary for both straight and zigzag stitching.
When used with a straight stitch setting, the lever places stitching in left, centre or right needle position
(see pages 19 and 20).
When used with a decorative stitch setting, the lever controls width of primary patterns and produces
variations of combination patterns (see pages 34 and 36).
To position, depress lever and slide il left or right to desired setting. Numerals indicate five positions
but intermediate settings may also be used.

General Purpose Throat Plate and Presser Foot.
Use general purpose throat plate and presser foot for all utility sewing, long straight seams, etc., and
where there is occasion to alternate between straight and zigzag stitching.
STRAIGHT STITCH THROAT PLATE AND
PRESSER FOOT
Use the straight stitch throat plate and presser
foot where fabric and sewing procedure require
close control . . . for precision stitching of curved
and scalloped edges, top stitching, edge stitching,
etc.
For best results, this equipment should be used
when stitching sheer and filmy fabrics, knits and
tricots (particularly synthetics) and all soft spongy
materials.

To meet special requirements a line of stitching may be placed to the left or to the right of centre.
Lever setting 1 locates stitching to the extreme left; lever setting 5 locates it to the extreme right. Inter
mediate left and right positions result when settings 2 and 4 are used.
The general purpose throat plate and presser foot must be used with left and right needle positions.
Do not make any lever adjustments while the needle is in the fabric.

lower presser foot. Raise stitch regulator to reverse.
Back stitch to edge of fabric for reinforcement. Lower regulator for forward stitching of seam. Raise
stitch regulator,
22
SEWING A SEAM (Cont'd.)
Back stitch to reinforce end of seam, and lower regulator to forward stitching position.
With take-up lever at highest point, raise presser foot and remove fabric.
23
GUIDING AND SUPPORTING FABRIC
\
Most fabrics need only to be guided in front of the presser foot.
Fabrics of unusual texture and weave, filmy sheers, crepes, tricots, etc., require support while being
stitched.
For such fabrics, use the straight stitch throat plate and presser foot, and apply gentle tension to the
seam by holding the fabric in front and at the back of the presser foot as illustrated.
24
PRESSURE ADJUSTMENTS
To decrease pressure, turn thumb screw upward.
To increase pressure, turn screw downward.
Decrease
Increase
Pressure is the force the presser foot exerts on fabric while it is
being stitched.
. Smooth, even handling of several thicknesses of fabric results when
pressure is correctly regulated.
Too light a pressure will result in irregular feeding which affects
both quality of stitch and evenness of seams.
Too heavy a pressure not only affects stitch and seam quality but
will mar smooth surfaces and pile fabrics.
Surface finish, as well as the weight and texture of the fabric, must
be considered in determining the amount of pressure needed.
25
NEEDLE THREAD TENSION
STRAIGHT STITCHING
Needle thread tension too tight —
correct by setting dial to lower
number.
Needle thread tension too loose —
correct by setting dial to higher
number.
A perfectly locked stitch results with the upper and lower tensions balanced so that needle and bobbin
threads are drawn equally into fabric.
