This product is equipped with a polarized alternating current line plug (a plug having one blade wider than other. This plug will fit into the power outlet only one way. This is safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact an electrician to replace the obsolete outlet. Do not defeat the safety purpose of the polarized plug.

HOW TO CONNECT THE MACHINE TO THE POWER SUPPLY
1. Fit the machine plug into the machine.
2. Plug the machine to the power supply.
Note: *Before plugging in the machine, ensure that 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
automatically. *Before using the machine, practice controlling the speed with
out threading.
HOW TO REPLACE THE SEWING LAMP
Before replacing a lamp, disconnect the machine from the power supply.
To replace the sewing lamp, use the sewing lamp holder which you may find in the accessory storage.
Push the holder from bottom until the lug over the sewing lamp, and twist the holder together with sewing lamp in counterclockwise, until the lamp is taken down.
To replace the new sewing lamp, twist the holder together with sewing lamp in clockwise.

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, or fine fabrics and synthetics, use a BLUE SHANK needle. The blue shank needle
effectively prevents skipped stitches. *When sewing very fine fabrics, sew over a piece of paper to prevent yarn distortion.

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.
The needle thread and the bobbin thread Should interlock in the center of two layers of fabric.
rem
Remember the higher the number, the tighter the tension. Correctly balanced tension 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.

STITCH LENGTH DIAL REVERSE LEVER
STITCH LENGTH DIAL To change the length of the stitches proceed as follows: Turn the dial so that the number for the required stitch length is at setting mark. The numbers indicate the approximate is at setting mark. The numbers indicate the approximate stitch length in millimeters. The lower the number, the shorter the stitch.
REVERSE STITCH Press downward the reverse lever and hold for reverse stitching. Fabric will immediately start feeding backwards. Release the lever and machine will resume normal forward sewing. Release the lever and machine will resume normal forwarding sewing. Very useful for fastening ends of seams and darts without having to tie threads, and for strengthening seams.

SEWING BUTTONHOLES
1. Set the stitch width control at “3”, and stitch length dial at the buttonhole symbol then pass the needle thread through the opening in the zigzag foot and draw both needle and bobbin threads to the left side. Turn the balance wheel towards you until the needle comes to point (1).
2. Lower the foot and sew slowly until the desired length is sewn, then stop the machine at point (2). Stop with the needle in the down position and on the right side of the zigzag sewing.
3. Lift the presser foot and using the needle as a pivot, turn the fabric 180 degree lower the presser foot, raise the needle, set the stitch width control at “5”. Sew several stitches of bar back until the needle is at point (3).
4. Raise the needle and set stitch width control at “3” then sew the left side of buttonhole the same length as the right side of buttonhole. Stop the machine at point (4).
5. Raise the needle and set stitch width control at “5”, then sew several stitches of final bar tack. Stop the machine when the needle is at point (5).
6. Cut the buttonhole open carefully by using a seam ripper, taking care not to damage the bar tacks.
Note: *To make a heavier buttonhole, set the stitch length control between the buttonhole symbol and “O”. Note: *To find the most suitable stitch length, it is better to sew a sample buttonhole on a piece of waste fabric.
*When sewing very fine fabrics and synthetics, decrease the pressure of the foot and sew over a piece of
paper to prevent yarn distortion.

SEWING EMBROIDERY
Place the fabric in embroidery hoop. Place darning plate over needle plate (see below). Lower the presser foot lifter. Hold the embroidery hoop firmly with your hand.
While sewing the desired pattern, move the embroidery hoop slowly and do not allow your fingers to get near the needle. *Set the needle thread tension a little looser so that the bobbin thread is not pulled through to the right side of fabric. (see page 13). *It is recommended to mark the required embroidery pattern on the right side of the fabric
with a pencil or tailor’s chalk.
DARNING PLATE
There are 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. See above for embroidery.
