and stop your buttonhole at precisely the correct point.

Blindhem Foot 3

This foot is used for blindhem stitches. The toe on the foot guides

the fabric. The red guide on the foot is designed to ride along the

fold of the hem edge.

Note: Always use at least 5mm stitch width when using Blind Hem Foot

3. If using a stitch width other than the recommended, swing the needle

by turning the hand wheel to make sure the needle doesn’t hit the metal

pin in the foot.

One-Step Buttonhole Foot 5B (for 160s)

This foot has a space in the back for a button used to set the size of

Zipper Foot 4

This foot can be snapped on either the right or the left of the nee-

dle, making it easy to sew close to both sides of the zipper teeth.

Move the needle position to the right or left to sew closer to zipper

teeth.

Free Arm

To use the free arm, slide off the accessory

Remove the tray by sliding it to the left.

Leveling the Machine Base Plate

Narrow thread spool

Large thread spool

Spool Pins

Your machine has two spool pins, a main

spool pin and an auxiliary spool pin. The

spool pins are designed for all types of

thread. The main spool pin is used in a

FDOSRVLWLRQWKHWKUHDGVSRROURWDWHV8VH

the horizontal position for normal threads

and the vertical position for large spools or

specialty threads.

Main Spool Pin

Place a spool cap and the thread spool on

the spool pin. Make sure that the thread

reels off the spool counter clock-wise and

slide on a second spool cap.

Note: Not all thread spools are manufactured in

the same way. If you experience problems with

the thread, turn it in the opposite way or use the

vertical position.

Use a spool cap slightly larger than the

thread spool. For narrow thread spools, use

a smaller spool cap in front of the spool. For

large thread spools, use a larger spool cap

in front of the spool.

The flat side of the spool cap should be

pressed firmly against the spool. There

should be no space between the spool cap

and the thread spool.

Auxiliary Spool Pin

The auxiliary spool pin is used when wind-

ing a bobbin thread from a second spool of

thread or for a second spool when sewing

with a twin needle.

Insert the auxiliary spool pin into the hole at

WKHWRSRIWKHPDFKLQH$6OLGHRQDODUJH

thread spool. This is to prevent the thread

3. Let the needle threader gently swing

back. The hook pulls the thread through

the needle eye and forms a loop behind

the needle. Pull the thread loop out

behind the needle.

4. Raise the presser foot and place the

thread under it.

Note: The needle threader is designed to be used

for size 70-120 needles. You cannot use the

needle threader for size 60 needles or smaller,

wing needles or twin needles.

There are also some optional accessories that

require manual threading of the needle.

When threading the needle manually, make sure

that the needle is threaded from front to back.

Threading for Twin Needle

Replace the sewing needle with a twin needle. Make sure that the presser foot is raised and

the needle is in its highest position.

1. Place the thread spool on the spool pin

and fit the appropriately sized spool

cap. Insert the auxiliary spool pin.

sure can improve the result.

For very light fabrics, loosen the pressure by

turning the dial counterclockwise.

Note: If the dial is turned counterclockwise too

much, it could come off. If this happens, simply re-

place the dial and turn it clockwise until it stays in

place.

For heavy fabric, tighten the pressure by turn-

ing the dial clockwise.

Note: If the dial is turned clockwise until it comes

to a stop, it has reached the maximum pressure

available. Do not try to turn the dial any further!

For the best stitch appearance and durability,

make sure the needle thread tension is correctly

adjusted. For general sewing, the threads

evenly meet between the two layers of fabric
