PREFACE

Thank you for your purchase of this sewing machine. This machine will provide you with excellent performance in sewing from light to heavy material (lawn to

denim). Please refer to this booklet for proper use and optimum service. To get the most out of your sewing machine, read the entire operator’s manual before attempting to

operate the machine. Then familiarize yourself with the machine by following the operator’s manual page by page.

Safety Cautions:

• Be sure that the electrical voltage of the socket outlet (wall receptacle) is the same as the rated voltage of the motor.

• Disconnect the power-line plug from the socket outlet when changing needles, presser foot or

throat plate, or when leaving the machine unattended. This eliminates the possibility of start

ing the machine by accidentally pressing the speed controller.

• Do not pull the fabric while you are stitching as this may deflect the needle, causing it to break.

• Before cleaning your machine, disconnect the power-line plug from the socket outlet.

• Do not attempt to adjust the motor belt. Contact your nearest Service Center should any adjustment be required.

• Handle the foot controller with care and avoid dropping it on the floor. Be sure not to place anything on top of it.

• When sewing closely watch the area being sewn to avoid injuries from needles and knives.

• Use only the handle to lift and move the machine.

To ensure that you are always provided with the most modern sewing capabilities, the manufacturer reserves the right to change the appearance, design or accessories of this sewing machine when considered necessary without notification or obligation.

The thread tensions become tighter as the dials are turned to higher numbers. This is indicated through

out the manual. (+) symbol means tighter tension or higher number and (—) means looser tension or lower number. The tension settings shown on this page as well as throughout the operator’s manual are suggested guides. Adjust thread tensions to suit the fabric and size of thread used. For best results make tension adjustments in small increments of no greater than half a number at a time.

4. Preparation for sewing

Connect the machine plug to the electrical receptacle of your machine and the power line plug to the wall receptacle.

To run the machine and control the speed, press the speed controller. The harder you press, the faster the machine will sew. To stop the machine from sewing, remove your foot from the speed controller.

Caution:

• Be sure that the electrical voltage of the socket outlet (wall receptacle) is the same as the rated voltage

of the motor.

• Handle the foot controller with care and avoid dropping it on the floor. Be sure not to place anything

on top of it when not in use.

• Disconnect the power-line plug from the socket outlet when changing needles, presser feet or throat plates, or when leaving the machine unattended. This eliminates the possibility of starting the machine by accidentally pressing the speed controller.

• Before cleaning your machine, disconnect the power-line plug from the socket outlet.

5. Preparation for threading

• Setting up the thread guide holder

Extend the thread guide holder as far as possible and set the thread guides so that they are located right above the spool pins.

Place the thread on the spool stand as sho^vn

above.

• How to insert the needles

Use Singer needles Cat. No. 2054 available in sizes #14 and (#10)

To remove the needles:

• Be sure the power line plug is disconnected from the wall receptacle.

• Turn the hand wheel toward you until the needle is at its highest position. Loosen the needle set screw with a screwdriver and remove needles.

To replace the needle:

• Insert the needles into the needle bar hole as far as they will go with flat surface to the rear and securely tighten the needle set screw.

Remove

Flat surface to the rear

Note: When both the left and right needles are inserted, the left needle will be slightly higher than

the right.

Be sure looper cover is closed when sewing.

(1) Push the cover to the right as

far as it will go and

(2) Pull cover down toward you.

• How to remove cylinder cover

0 While pulling the cylinder cover to the left, (2) Lift cover upward and off the machine.

* Do not hold the cylinder cover when lifting or carrying the machine.

• How to thread the machine

To replace cover

(T) Place tab A under the throat plate. (2) Press cover downward to the right.

To thread the machine correctly, simply follow the steps on the following pages making reference to the threading chart on the inner side of the looper cover showing the threading paths in different colors.

• How to change threads

When you wish to change the left needle thread, right needle thread, left looper thread or right looper thread with a different thread, the following steps will make the changing convenient.

(1) Cut the thread near the spool and tie

the end to the thread you wish to

change to as shown in figure at right. (2) Raise presser foot. (3) Note tension reference numbers. (4) Turn the tension dials down toward the

(—) mark until the dial stops and draw

the thread out so that the tie knot of

the threads extend about 5 cm (2

inches) from the presser foot. When

drawing needle thread through the

needle eye, stop the tie knot before the

needle eye, cut the thread and pass it

through the needle eye.

(5) Return tension dials to reference num

bers.

When the machine is completely threaded,

turn the hand wheel toward you 2 or 3 turns while holding the 4 threads applying a slight tension as shown in figure at left.

After chaining off, make a test stitch on a sample of your fabric so that you can adjust the thread tensions correctly.

After completing the seam, chain off approx.

5 cm (2 inches) as shown in figure at left and

cut thread with scissors.
