When sewing several layers or thick fabrics, the presser foot
can be raised to a higher position for easy positioning of the
work. (A)
Attention:
Your SINGER®machine is adjusted to provide the best
stitch result at normal room temperature. Extreme hot and
cold temperatures can affect the sewn result.
Two Step Presser Foot Lifter
The presser foot pressure of the machine has been pre-set
and requires no particular readjustment according to the type
of fabric (light-or-heavy weight).
However, if you need to adjust the presser foot pressure, you
may turn the presser adjusting screw with a coin.
For sewing very thin fabric, loosen the pressure by turning
the screw counter counterclockwise, and for heavy fabric,
tighten by turning it clockwise.

Winding the Bobbin
- Place thread and corresponding spool holder on to spool
pin. (1/2)
- Snap thread into thread guide. (3)
- Wind thread clockwise around bobbin winder tension
discs. (4)
- Thread bobbin as illustrated and place on spindle. (5)
- Push bobbin spindle to right. (6)
- Hold thread end. (7)
- Step on foot control pedal. (8)
- Release the pedal after a few turns. Release the thread
and cut as close as possible to the spool. Press the pedal
again. Once the spool is full, it rotates slowly. Release the
pedal and cut thread. (9)
- Push bobbin spindle to left (10) and remove.
Please Note:
When the bobbin winder spindle is in “bobbin winding”
position, the machine will not sew and the hand wheel will
not turn. To start sewing, push the bobbin winder spindle
to the left (sewing position).

7
When inserting or removing the bobbin, the needle must
be fully raised.
- Open the hinged cover. (1)
- Pull the bobbin case tab (a) and remove the bobbin case.
(2)
- Hold the bobbin case with one hand. Insert the bobbin so
that the thread runs in a clockwise direction (arrow). (3)
- Pull the thread through the slit and under the nger. Leave
a 6 inch tail of thread. (4)
- Hold the bobbin case by the hinged latch. (5)
- Insert it into the shuttle. (6)
Attention:
Turn power switch to off (“O”) before inserting or removing
the bobbin.

Upper thread tension
Basic thread tension setting: “4”.
To increase the tension, turn the dial to the next number up.
To reduce the tension, turn the dial to the next number down.
1. Normal thread tension for straight stitch sewing.
2. Thread tension too loose for straight stitch sewing. Turn
dial to higher number.
3. Thread tension too tight for straight stitch sewing. Turn
dial to lower number.
4. Normal thread tension for zig zag and decorative sewing.
Correct thread tension is when a small amount of the
upper thread appears on the bottom side of fabric.
Lower thread tension
The bobbin tension has been set correctly at the factory, so
you do not need to adjust it.
Please note:
- Proper setting of tension is important to good sewing.
- There is no single tension setting appropriate for all stitch
functions, thread or fabric.
- A balanced tension (identical stitches both top and bottom)
is usually only desirable for straight stitch construction
sewing.
- 90% of all sewing will be between ”3” and ”5”.
- For zig zag and decorative sewing stitch functions, thread
tension should generally be less than for straight stitch
sewing.
- For all decorative sewing you will always obtain a nicer
stitch and less fabric puckering when the upper thread
appears on the bottom side of your fabric.
Thread Tension

This is a simple operation but it is important to carry out
correctly as by not doing so several sewing problems could
result.
- Raise the needle to its highest position by turning the
handwheel towards you (counterclockwise) so that the
mark on the handwheel points directly up. Raise the
presser foot to release the tension discs. (1)
Note: For safety, it is strongly suggested you turn off the
power before threading.
- Lift up the spool pin. Place the spool of thread on the
holder with the thread coming off the spool as shown. For
small thread spools, place small side of spool holder next
to spool.(2)
- Draw thread from spool through the upper thread guide (3)
and pulling thread through pre-tension spring as illustrated.
(4)
- Thread tension module by leading thread down right
channel and up left channel. (5) During this process it is
helpful to hold the thread between the spool and thread
guide.
- At the top of this movement pass thread from right to
left through the slotted eye of the take-up lever and then
downwards again. (6)
- Now pass thread behind the thin wire needle clamp guide
(7) and then down to the needle which should be threaded
from front to back.
- Pull about 6-8 inches of thread to the rear beyond the
needle eye. Trim thread to length with built in thread cutter.
(8)
Threading the Upper Thread

10
Hold the upper thread with the left hand. (1)
Turn the handwheel towards you (counterclockwise) lowering,
then raising needle.
Note:
If it is difcult to raise the bobbin thread, check to make
sure the thread is not trapped by the hinged cover or the
Removable Extension Table.
Raising the Bobbin Thread
Gently pull on the upper thread to bring the bobbin thread up
through the needle plate hole. (2)
Lay both threads to the back under the presser foot. (3)
Sewing

11
To select a stitch, simply turn the pattern selector dial. The
pattern selector dial may be turned in either direction.
For straight stitch, select pattern " " with the pattern
selector dial.
For zigzag stitch, select pattern " " with the pattern
selector dial.

Function of stitch length dial for when straight stitching
For straight stitch sewing, turn the Pattern Selector Dial to
the straight stitch setting. (1)
Turn the Stitch Length Dial, and the length of the individual
stitches will decrease as the dial approaches "0". The length
of the individual stitches will increase as the dial approaches
"4". (2)
Generally speaking, use a longer stitch length when sewing
heavier weight fabrics or when using a thicker needle or
thread. Use a shorter stitch length when sewing lighter weight
fabrics or when using a ner needle or thread.
Function of stitch length dial while zig-zag stitching
Turn the Pattern Selector Dial to " " . (3)
The density of zig-zag stitches increases as the setting of
stitch length dial approaches "0".
Neat zig-zag stitches are usually achieved at "2.5" or below.
Dense zig-zag stitches are called satin stitches. (4)

Sewing Straight Stitch
To begin sewing, set the machine for straight stitch. (1)
Place the fabric under the presser foot with the fabric edge
lined up with the desired seam guide line on the needle plate.
(2)
Lower the presser foot lifter, and then step on the foot control
to start sewing. (3)
