plug into power supply outlet.
3. Power / Light Switch
Your machine will not operate unless the power/ light switch is turned on.
This same switch controls both machine power and sewing light.
When leaving the machine unattended, or servicing the machine, remove
the power line plug from supply outlet.
4. Opening Front Cover
To open front cover, pull it to the right and down towards you.
5. Opening Working Table
To open working table, pull the release lever towards you with your right
hand, and lift the front of presser foot up with your left hand.
PREPARATION FOR THREADING
Thread Guide Pole
pole to the highest point until you hear it click. Place thread spools on pins and
draw thread through thread guides on the pole from rear to front.
Thread guide of pole can hold thread spools on the spool stand by pulling
down the pole as illustrated.
SPOOL CAPS FOR DOMESTIC TYPE SPOOLS
SPOOL DISC AND SPOOL HOLDERS FOR CONE SPOOLS
For large cone spools use the spool holders with the wide end at the top, and
for small ones, use the same spool holders but with the narrow end at the top.
SPOOL NETS
Polyester or bulky nylon threads become loose while unwinding. To keep
consistent feeding of such threads, utilize spool net sleeving over the spool.

CHANGING NEEDLE
Raise needle bar to its highest point by turning hand wheel towards you, but
leave presser foot down. Loosen needle clamp screw to remove the needle,
and place new needle with Flat Side Away From You, into the needle bar as
far as it will go, and tighten screw.
CUTTING WIDTH GAUGE
When using cutting width gauge, the fabric is cut down and sewn at same
distance from the edge of fabric within the distance of the width adjuster.
CHANGING PRESSER FEET
Be sure needle is in the up position. Raise presser foot lever.
1. Push foot release lever to remove the foot.
2. Place the desired foot on the needle plate aligning needle holes.
3. Lower the presser foot lever and push foot release lever so that the foot
holder snaps on the foot.

ADJUSTMENTS AND SETTINGS
STITCH LENGTH
Turn the stitch length dial until the required length is obtained.
The higher the number, the longer the stitch. This dial can adjust the stitch
length from 1 to 5 mm all so on Position P and R.

OPERATING INSTRUCTIONOPERATING INSTRUCTION
Overedge cutting width can be adjusted from 4 to 7
mm by simply turning overedge cutting width dial
according to the kind of fabric.
It is set at standard width of 6 mm when delivered
from the factory.
Turn it towards “5” if fabric edge curls while sewing.
(Fig. 1)
Turn it towards “7 “ if loops hang off the edge. (Fig.
2)
Loops may hang off the edge, when you sew with
lightweight fabric using 3 threads (right needle
only), and setting cutting width dial at 4 - 5 (Fig. 3).
In such a case change the stitch finger (A) to (B) to
get neat stitching (Fig. 4).
The differential feed has two independent feed dogs, one front (A) and one rear
(B).
Each feed dog has an individual feed mechanism which enables the feeding of
material at a different ratio.
DIFFERENTIAL FEEDADJUSTING OVEREDGE CUTTING WIDTH
STITCH FINGER (B)
FOOT PRESSURE REGULATOR
Presser foot pressure has been correctly set at the
factory, so you do not need to adjust it for most of
ordinary sewing. If adjustment is necessary, turn
the foot pressure regulator to higher number to
increase or to lower number to decrease pressure.
SEWING WITH EXTRA HEAVYWEIGHT FABRIC OR MULTIPLE LAYERS OF FABRIC
A wide range of fabric can be overlocked on this
machine, but it is recommended to tighten screw as
illustrated, when sewing with extra heavyweight
fabrics or mulitiple layers of fabric. Open working
table for adjustment.
Loosen the screw when sewing with light to normal
weight fabric or turning overedge cutting width dial,
or otherwise fabric may not be well cut.
The machine is set for normal weight fabrics from
the factory.
POSITIVE DIFFERENTIAL FEED
WHEN SET FOR POSITIVE DIFFERENTIAL FEED, the front feed dog (A)
makes a longer stroke than the rear feed dog (B).
This has the effect of accumulating material under the presser foot to offset the
wavering on the fabric.
NEGATIVE DIFFERENTIAL FEED
WHEN SET FOR NEGATIVE DIFFERENTIAL FEED, the front feed dog (A)
makes a shorter stroke than the rear feed dog (B).
This has the effect of stretching material under the presser foot to offset the
puckering on the fabric.
SETTING DIFFERENTIAL FEED
Set by simply moving the differential feed control lever in the direction desired
referring to the chart below.
The adjustment can be made between 0.7 (negative effect) and 2 (Positive
effect). These settings give the best ratio of feeding.
For normal sewing, the lever should be set at 1.
The lever can be reset even while sewing.
