SERVICING OF DOUBLE INSULATED PRODUCTS
In a double-insulated product, two systems of insulation are provided instead of grounding. No
ground means is provided on a double-insulated product, nor should a means for grounding
be added to the product. Servicing of a double-insulated product requires extreme care and
knowledge of the system and should be done only by qualied service personnel. Replacement
parts for a double-insulated product must be identical to those parts in the product. A double-
insulated product is marked with the words “DOUBLE INSULATION” or “DOUBLE INSULATED”.

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)
- 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).

- When inserting or removing the bobbin, the needle must be
fully raised. (1)
- Remove the bobbin cover plate and bobbin. (2)
- Insert the bobbin in the bobbin case with the thread running
in a counterclockwise direction (arrow). (3)
- Pull the thread through the slit (A). (4)
- With a finger held gently on top of the bobbin, place thread
into guides as shown. (5)

cutter at point (B). Replace the bobbin cover plate. (6)
Attention:
Turn power switch to off (“O”) before inserting or removing
the bobbin.
Inserting the Bobbin

8
This is a simple operation but it is important to carry out
correctly as by not doing so several sewing problems could
result.
- 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.
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 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)
Threading the Upper Thread

9
- Raise the needle to its highest position.
- Pass thread around thread guide (A). (1)
- Press lever (B) down as far as it will go. (2)
- The threader automatically swings to the threading position
(C).
- Pass the thread in front of the needle around the hook (D)
from bottom to top.
- Release lever (B). (3)
- Pull the thread through the needle eye.
Attention:
Turn power switch to off (“O”)!
Automatic Needle Threader

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.
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)
Raising the Bobbin Thread

Thread Tension
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.
