SELECTION OF STITCHES
This machine is capable of producing various types of stitches according to the combination of needle positions,
threading methods, tension adjustment, and use of convertible right looper/spreader
* Depending on the needle positions used, this machine can sew 2-thread and 3-thread combinations with width of 3.5mm overedge
and a 5.7mm wide overedge seams.
For overedging heavyweight fabrics, the seam width can be increased still more by turning the overedge seam width adjustment
knob. (See page 28)

This overlock uses a flat shank domestic needle that
eliminates the possibility of inserting the needle backwards.
Do not attempt to use an industrial sewing machine
needle of any size or type in this overlock.
Needle size 14 is furnished with the machine. Regular point
needles for sewing woven fabrics and ball point needles
are available for sewing knits. Both types are available in
sizes 10, 12 & 14.

HOW TO ATTACH & REMOVE THE
PRESSER FOOT
Note: Do not use presser feet that are made for other
machines or other brands. The use of such presser
feet may result in interference with the needle and
knife and can be dangerous.
The snap-on type presser foot of this machine permits
easy removal and replacement.
CAUTION: Be sure to turn the machine to the “Off”
position and disconnect the power cord when
attaching or removing the presser foot.
How to attach the presser foot:
1. Place the presser foot plate on the needle plate
under the presser foot shank so that the hinge
pin “C” will fit in slot “B” of the shank. Then lower
the presser bar lifter.
2. If the presser foot plate can not be placed under
the presser foot shank easily, raise the presser
bar lifter to its highest position. While holding it
in this position, place the presser foot plate under
the presser foot shank. Then lower the presser bar
lifter.
3. Raise the presser bar lifter and make sure that the
presser foot plate is properly attached to the presser
foot shank.
How to remove the presser foot:
1. Raise the presser foot and the needle bar to its
highest position.
2. Press the white colored lever “A” located on the
back of the presser foot shank and remove the
presser foot plate.
3. If it is difficult to remove the presser foot plate from
under the presser foot shank, raise the presser bar
lifter to its highest position. While holding it in this
position, remove the presser foot plate.

9. Pull about 4 inches (10 cm) of thread through the
looper and place to the back of the needle plate.
Note: If the upper looper thread breaks during sewing,
this may be caused by the lower looper thread
getting caught on the upper looper. If this
happens, lower the upper looper by turning the
hand wheel, remove the lower looper thread from
the upper looper, and re-thread the upper looper
from at least the tension disc position.

HOW TO CHANGE THE THREADS
TIE-ON METHOD
If you wish to change the thread type or color without
rethreading the machine:
1. Cut the threads near the spools. (Fig. 1)
2. Place the new spool of thread on the stand.
3. Tie the new threads and the old thread ends
together making sure that the correct threads are tied
together. (Fig. 2)
4. Cut the thread ends to approximately 1-inch (2-3 cm)
in length. If the threads are cut too short, they may
come undone.
5. Firmly pull both threads to make sure that the threads
are tied securely.
6. Note the tension dial settings. (Fig. 3)
7. Turn the tension dials down until they stop at
position “0”. (Fig. 4)
8. Pull the threads through the machine one at a time.
If the threads do not pull easily, check for any tangles
on the thread guides or looping under thread stand.
9. When pulling the thread through the needle, STOP
when the knot is in front of the needle. (Fig. 5)
10. Cut the thread and thread it through the needle eye.
11. Return the tension dials to the previous settings.

HOW TO ADJUST THE STITCH
LENGTH
. The stitch length dial located on the right side of the
machine should be set at the 3 mm (1/8-inch) setting
for most sewing conditions.
. When sewing heavy weight fabrics, adjust the stitch
length to 4 mm (5/32-inch).
. Adjust the stitch length to 2 mm (5/64-inch) when
sewing light weight fabrics to obtain excellent seams
without puckering.
HOW TO ADJUST THE SEAM
WIDTH
. An overedge seam width can be adjusted by
repositioning the needle position and also with the
width adjustment.
1. Adjusting the seam width by changing the needle
position:
a) When only left needle is used ............... 5.7 mm
(7/32 inch)
b) When only right needle is used ............. 3.5 mm
(9/64 inch)
2. Adjusting the seam width with the adjustment knob:
a) When only left needle is used ........ 3.5 to 5.7 mm
(13/64 to 17/64 inch)
b) When only right needle is used ..... 3.0 to 4.5 mm
(1/8 to 11/64 inch)
3. Using the width adjustment knob:
Caution: Be sure to turn the power switch to the “Off”
position before making any adjustments to the machine.
a) Remove the waste container.
Note: Opening the front cover will make it easier to make
any adjustments.
b) Push the upper knife to the right and while holding
the knife in this position, turn the adjustment knob
left or right to get the desired width using the
graduation on the needle plate as a guideline.
Note: Placement of the upper knife in non-working
position will make adjustment easier.
Caution: Always close the front cover before operating
the machine.
