When sewing several layers or thick fabrics, the presser foot
can be raised for easy positioning of the
work. (A)
to a higher position

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,
turn the presser adjusting screw with a coin.
For sewing very thin fabric, loosen the pressure by turning
the screw counter clockwise, and for heavy fabric, tighten by
turning it clockwise.

This is a simple operation but it is important to carry out correctly
as by not doing so .
- Start by raising the needle to its highest point (1), and
continue turning the handwheel counterclockwise until the
needle just slightly begins to descend. Raise the presser
foot to release the tension discs.
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)
-
several sewing problems could result
Note:
Now pass the thread behind the horizontal thread guide,
and then 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)

Hold the upper thread with the left hand. Turn the handwheel
(1) towards you (counterclockwise) lowering, then raising
needle.
If it is difficult to raise the bobbin thread, check to make sure
the thread is not trapped by the hinged cover or the
Removable Extension Table.
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)

Upper thread tension
Lower thread tension
Please note:
Basic thread tension setting: "4". (1)
To increase the tension, turn the dial to the next number up.
To reduce the tension, turn the dial to the next number down.
A. Normal thread tension for straight stitch sewing.
B. Thread tension too loose for straight stitch sewing. Turn
dial to higher number.
C. Thread tension too tight for straight stitch sewing. Turn
dial to lower number.
D. 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.
-.
- 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.
The bobbin tension has been set correctly at the factory, so
you do not need to adjust it.
Proper tension setting is important for strong seams

Pattern Selector Dial in gray. To select the patterns indicated
with the gray color, turn the Pattern Selector Dial. (e) Use the
Stitch Length Dial (d) to adjust the stitch length as desired for
the project. Use the Stitch Width Dial (c) to adjust the width
of the stitch as desired.
Stitches in the bottom row of the diagram are indicated on
the Pattern Selector Dial in blue. The blue indicates that the
stitch is a stretch stitch pattern, and information on how to
sew these stretch patterns is on page 18.

How to Choose Your Pattern

The needle position can be altered with the "Three needle
position dial". For normal work, the needle position is middle.
For edge stitching or sewing parallel lines of top stitch, select
needle position left or right. For twin needle stitching, needle
position is middle.

Function of stitch width dial
Function of stitch length dial while zig-zag stitching
Function of stitch length dial for when straight stitching
The maximum zigzag stitch width for zigzag stitching is 6mm;
however, the width can be reduced on any patterns. The
width increases as you move zigzag dial from "0" - "6". (1)
Set the Pattern Selector Dial to zig-zag.
The density of zig-zag stitches increase as the setting of stitch
length dial approaches "0".
.(2)
Dense zig-zag stitches are called satin stitches. (2)
For straight stitch sewing, turn the Pattern Selector Dial to
the straight stitch setting. Turn the Stitch Length Dial, and the
length of the individual stitches will decrease as the dial
approached "0". The length of the individual stitches will
increase as the dial approaches "4". 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
finer needle or thread.
Standard zigzag stitches are usually achieved at "3" or below
