IMPORTANT SAFETY INSTRUCTIONS

When using an electrical appliance, basic safety precautions should always be followed, including the

followings:

Read all instructions before using this appliance.

DANGER— To reduce the risk of electric shock:

1. An appliance should never be left unattended when plugged in. Always unplug this sewing machine

from the electric outlet immediately after using and before cleaning.

2. Always unplug before replacing a sewing machine bulb. Replace bulb with same type rated

15 Watts.

WARNING— To reduce the risk of burns, fire, electric shock, or injury to persons:

1. Do not allow to be used as a toy. Close attention is necessary when this sewing machine is used by

or near children.

2. Use this appliance only for its intended use as described in this owner’s manual.

Use only attachments recommended by the manufacturer as contained in this owner’s manual.

3. Never operate this sewing machine if it has a damaged cord or plug, if it is not working properly, if it

has been dropped or damaged, or dropped into water.

Return this sewing machine to the nearest authorized dealer or service center for examination,

repair, electrical or mechanical adjustment.

4. Never operate the appliance with any air opening blocked. Keep ventilation openings of this sewing

machine and foot controller free from accumulation of lint, dust and loose cloth.

5. Never drop or insert any object into any opening.

6. Do not use outdoors.

7. Do not operate where aerosol (spray) products are being used or where oxygen is being

administered.

8. To disconnect, turn all controls to the off (“O”) position, then remove plug from outlet.

9. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.

10. Keep fingers away from all moving parts. Special care is required around the sewing machine

needle.

11. Always use the proper needle plate. The wrong plate can cause the needle to break.

12. Do not use bent needles.

13. Do not pull or push fabric while stitching. It may deflect the needle causing it to break.

14. Switch this sewing machine off (“O”) when making any adjustment in the needle area, such as

threading the needle, changing the needle, threading the bobbin or changing the presser foot, and

the like.

15. Always unplug this sewing machine from the electrical outlet when removing covers, lubricating, or

when making any other adjustments mentioned in this owner’s manual.

GETTING READY TO SEW

Connecting the Machine to the Power Supply

1Turn off the power switch, and connect the

machine plug to the machine socket.

2Connect the power supply plug to your power

supply.

3Turn on the power switch.

Controlling Sewing Speed

Sewing speed can be varied by the foot control.

The harder you press on the control, the faster the

machine runs.

Step on the foot control with the presser foot lifter up, and

practice controlling the speed.

For Your Safety:

* While the machine is in operation, always keep your

eyes on the sewing area, and do not touch any moving

parts such as the thread take-up lever, loopers,

handwheel or needles.

*Always disconnect the machine from the power

supply:

—when leaving the machine unattended.

— when attaching or removing parts.

— when threading or cleaning the machine.

* Do not place anything on the foot control,

except when the machine is in use.

Operating Instructions:

•The symbol “O” of a switch indicates the

“off” position of a switch.

•For appliances with a polarized plug (one

blade wider than the other): To reduce the

risk of electric shock, this plug is intended

to fit in a polarized outlet only one way. If

it does not fit fully in the outlet, reverse

the plug. If it still does not fit, contact a

qualified electrician to install the proper

outlet. Do not modify the plug in any way.

Foot controller Model YC-482-J

is for use with sewing

machine model 900P.

Chain Stitch

This stitch is sewn with a single needle and forms a chain

of looper thread on the wrong side of the fabric.

This is a durable and flexible stitch used for seaming knit

fabrics, attaching elastics, attaching bias tapes etc.

Thread one of the three needles and looper. Remove the

needles not to be used (see page 8).

NOTE:

Tighten the needle clamp screw on the side that is not

being used to prevent losing the screws.

Balancing the thread tension

1Set the tension dials as follows:

q Needle thread tension dial: 3

w Looper thread tension dial: 2

NOTE:

Adjust the tension dial for the needle being used.

2Check the tension balance by test stitching on the

same fabric and threads as actual garment. Fine-tune

the tension as necessary.

Balanced tension:

The straight stitch on the right side of the fabric is straight

and even. The looper thread forms a chain.

q Wrong side of the fabric

looper thread tension to correct it.

(B) If the needle thread tension is too tight:

–The fabric puckers.

Loosen the needle thread tension, and/or tighten the

looper thread tension to correct it.

Finishing the Seam

To achieve the best results, use a piece of scrap fabric at

the beginning and end of the seam.

Beginning of the seam

1Raise the presser foot and insert a piece of scrap

fabric under the foot. Lower the foot and turn the

handwheel several times toward you.

Depress the foot control to start sewing slowly.

qHandwheel

2Stop sewing at the end of the scrap fabric.

Insert the work fabric after the scrap as shown, then

start sewing on the work fabric.

wScrap fabric

eWork fabric

4 Cut the connecting threads between the work fabric

and scrap fabric.

tConnecting threads

Knotting the threads

Draw the needle threads to the wrong side of the

fabric by using a pair of tweezers and knot them together.

Removing the Fabric in the Middle

of the Stitching

1Raise the needles to their highest position by turning

the handwheel toward you.

qHandwheel

2Raise the presser foot with the presser foot lifter.

wPresser foot lifter

3Pull the needle threads before the needle eyes.

This prevents the threads from being caught when

removing the fabric.

4Pull the fabric to the rear.

5Remove the fabric and cut the threads with the thread

cutter.

eThread cutter

Hemming with the Cover Stitch

1Fold up the edge of the fabric to the wrong side and

press.

2Draw a line with a tailor’s chalk on the right side of the

fabric to mark the fabric edge.

3Place the fabric so the left needle drops just to the

left side of the marked line. Lower the presser foot.

4Sew carefully along the marked line.

5After finishing sewing, raise the presser foot and

remove the fabric to the rear.

6Draw the needle threads to the wrong side of the

fabric and knot them together.

Free Arm Hemming

The extension table can be detached for free arm

hemming on the tubular parts of the garments, such as

sleeves, cuffs etc.

1Detach the extension table (see page 5).

2Stitch the hem in the same way as hemming with

cover stitch.

3Continue to sew over the stitches 2” (4 to 5 cm)

beyond the beginning of the seam and stop the

machine.

Cut the threads at the beginning and at the end.
