CONGRATULATIONS ON CHOOSING THIS COMPACT OVERLOCK MACHINE
Your machine is a high quality, easy-to-use product. To fully enjoy all the features, we suggest that you study this booklet.
If you need more information regarding the use of your machine, your nearest authorized dealer is always happy to be of service.
Enjoy yourself!
CAUTION
When threading or replacing needle, the main power and light switch of the machine must be switched off or the plug must be removed from the socket-outlet.
When the machine is not in use, it is recommended that the electric supply plug is disconnected from the wall socket to avoid any possible hazards.
Notes on the motor
-The maximum operating speed of this sewing machine is 1,000 stitches per minute, which is quite fast compared to the normal operating speed of 300 to 800 stitches per minute for the ordinary sewing machine.
-The bearings in the motor are made of a special material (oil-impregnated alloy mounted in felt heat-treated with oil) that enables them to withstand long hours of continuous operation.
-Continuous operation of the sewing machine can cause heat to build in the motor area, but not enough to adversely affect its performance.
It is important to keep fabric and paper away from the air openings on the back and sides of the machine so air can get to these openings.
-When the motor is running, sparks can be seen through the air openings in the motor bracket on the side opposite the handwheel. These sparks are produced by the carbon brushes and the commutator, and are part of the machines normal operation.
WARNING LABELS (for complying with UL and CSA requirements) The following warning labels are on the machine.
Be sure to observe the precautions described in the labels.

Differential feed
There are two sets of feed dogs under the presser foot to move the fabric through the machine. The differential feed controls the movement of both the front and the rear feed dogs. When set at 1, the feed dogs are moving at the same speed (ratio of 1). When the differential feed ratio is set at less than 1, the front feed dogs move less than the rear feed dogs, stretching the fabric as it is sewn. This is effective on lightweight fabric that may pucker. When the differential feed ratio is set at greater than 1, the front feed dogs move more than the rear feed dogs, gathering the fabric as it is sewn. This function assists in removing rippling when sewing stretch fabrics.

An example
When stretch material is sewn without using the differential feed, the fabric will be wavy.
To get a smooth finish, adjust the feed ratio from 1.0 toward 2.0.
(The feed ratio required depends on the elasticity of the material.)
The more elastic the material, the further toward 2.0 the differential feed ratio should be set. Test sew with a scrap of the fabric to fi nd the correct adjustment.
CAUTION
When sewing thick non-stretchable material such as denim, do not use the differential feed as it may damage the fabric.

Adjusting the tension dials
There is a thread tension dial for each needle thread, the looper thread and the top cover thread. The correct thread tension may vary according to the type and thickness of the fabric and the type of thread used. Thread tension adjustments may be necessary for any change in sewing materials.

To remove:
1.Turn off the main power and light switch.
2.Turn the handwheel so that the line on the handwheel is aligned with the line on the machine. (See “Turning direction of handwheel” in CHAPTER 1.)
3.Loosen the corresponding needle set screw by turning it with the included hexagonal driver toward 2 in the illustration, and then remove the needle.
To install:
1.Turn off the main power and light switch.
2.Turn the handwheel so that the line on the handwheel is aligned with the line on the machine.
3.Hold the needle with its fl at side away from you and insert it up as far as it will go.
4.Tighten the needle set screw securely by turning it with turning the included hexagonal driver toward 1 in the illustration.
NOTE:
Be sure to insert the needles all the way.
CAUTION
Always be sure to turn off the power before removing/inserting the needle.
Do not drop the needle and needle set screw in the machine, otherwise it may be damaged.

Using the thread
spool cap
When using sewing thread spools, the thread spool cap should be used as illustrated below. Make sure that the spool notch is on the bottom.

1 Thread spool cap
CAUTION
Before using a thread spool, be sure to remove the spool cushion.
Before using loosely spun nylon thread, be sure to install the spool cushion.
If the thread spool cap is not fully pushed down, the thread may become entangled on the spool pin or the needle may bend or break.
Spool mat
When using thread spools or loosely spun thread that easily slips off the spool, place this mat under the spool.
This prevents the thread from becoming entangled on the spool pin.
Using the spool mat
1.Remove the spool cushion, and then place the spool mat on the spool pin.
2.Place the thread spool (with the spool notch at the bottom) on the spool pin, and then place the thread spool cap on top and fully push it down.

Using the thread net
If you are sewing with loosely spun nylon thread, we recommend that you cover the spool with the included net in order to prevent the thread from slipping off the spool.
Adapt the net to the shape of the spool.
Before threading
1.Turn off the main power and light switch for safety.
2.Raise the presser foot using the presser foot lever.
3.Turn the handwheel so that the line on the handwheel <A> is aligned with the line <B> on the machine. (See “Turning direction of handwheel” in CHAPTER 1.)
