HOW TO CONNECT THE MACHINE TO THE POWER SUPPLY
1.Fit the machine plug into the machine.
2.Plug the power cord to the power supply.
Note:*Before plugging in the machine, ensure the voltage and
number of cycles indicated, conforms to your electrical
power supply.
HOW TO USE THE FOOT CONTROL
Sewing speed can be varied by the foot control. The harder you press on the controller, the faster the machine runs.
Note:*By releasing the controller, the machine stops running auto-
matically.
*Before using the machine, practice controlling the speed
without threading.
HOW TO REPLACE THE SEWING LAMP
The sewing lamp is located behind the face plate.
Remove the face plate by loosing the screw of the face plate.
Bulb type: To remove...Unscrew
To replace...Screw
Note:*Before replacing a bulb, disconnect the machine from the
power supply.
*Bulbs are available from sewing machine retailers.(Use a
15-Watt bulb)
Caution!
Before leaving the machine, changing parts or doing any other work on it, always disconnect the plug from the wall socket.

Note: *In general, fine threads and needles are used for sewing thin fabrics, and thicker threads and needles are
used for sewing heavy fabrics, Always test thread and needle size on a small piece of fabric which will
be used for actual sewing.
*Use the same thread for needle and bobbin.
*When sewing stretch, very fine fabrics and synthetics, use a STRETCH needle. The STRETCH
needle effectively prevents skipped stitches.
*When sewing very fine fabrics, sew over a piece of paper to prevent yarn distortion.
CHANGING THE NEEDLE
1. Turn the balance wheel towards you until the needle is in
its highest position.
2. Loosen the needle clamp screw by turning its top edge
towar ds you. Remove the needle from the clamp.

REGULATING THE THREAD TENSION
Generally, should any tension adjustment be necessary, the adjustment can normally be made by regulating the upper thread tension dial only. Bobbin thread tension has been adjusted at the factory and readjustment is seldom required except for special instances, thread and fabric.
Bobbin thread tension is just right when you can pull the thread from bobbin case easily with a little resistance.
Thread tension may be adjusted by tightening or loosening the thread tension dial.
Properly adjusted thread tension for straight sewing
The needle thread and the bobbin thread should interiock in the center of two layers of fabric
The needle thread is too tight
The bobbin thread appears on the upper surface of the fabrics
Loosen the needle thread tension by moving the dial to the lower number
*
How to adjust the bobbin thread tension
To increase tension, turn screw clock wise.
The needle thread is too loose
To decrease tension.
turn screw counterclock wise.
The needle thread appears on the underside of the fabrics
Tighten the needle thread tension by moving the dial to the higher number
Remember the higher the number, the tighter the tension. Correctly balanced tensions for one fabric may not be suitable for another. The required tension depends upon the stiffness of fabric, thickness of the fabric, numbers of layers of fabric being sewn, as well as the type of stitch you are making. It is better to test the stitching on a scrap of the fabric you are using before starting to make a garment. The general range for many fabrics is 3-5.

STITCH LENGTH DIAL (
Model 377 and 374 only)
To change the length of the stitches proceed as follows:

Lower the foot and swe the hem.
During sewing, fold the fabric to the left a little and allow it to run into the hemmer foot.
Make sure that the fabric does not move under the right half of the foot. The fabric must be fed into the scroll of the hemmer sufficiently so that the workpiece edge runs freely through the groove under the foot.

DARNING PLATE
There are a few times when you want to control the feeding of the fabric yourself. Raise needle to its highest position and raise presser foot. Place darning plate over needle plate aligning two pins of darning plate with holes of needle plate.
You may then determine the movement of the fabric yourself.

FREE ARM SEWING
This sewing machine can be used like a flat bed machine, but easily converts to a free arm machine by removing the extension table.
The free arm enables you to sew tubular types of pieces more easily.
Just slip the sleeve or pants leg on the free arm as shown above.
You will find many uses for this free arm feature such as:
1. Mend elbows and knees of garments more easily.
2. Sew in sleeves more easily. This is especially true when sewing
smaller garments.
3. Applique, embroider or hem around edges of cuffs or pants legs.
4. Sew in elastic casings in skirts or pants at the waist line.
