Step 4:

Threading the Right Needle: (GREEN)

• Slip the thread under the first guide directly below the

tension dial, and then under the guide just to the left of

the first guide.

• Run the thread over the top thread path indicated by a

green dot as shown.

• Thread through wire guide A located at the top of the

right needle and then through the eye of the needle.

• Slip thread under the overpass on the right of the foot

and then to the back of the serger, leaving

approximately 8 inches of thread.

Step 5:

Threading the Left Needle: (BLUE)

• Slip the thread under the first guide directly below the

tension dial.

• Run the thread over the bottom thread path indicated

by a blue dot as shown.

• Thread through wire guide B located at the top of the

left needle and then through the eye of the needle.

• Slip thread under the overpass on the right of the foot

and then to the back of the serger, leaving

approximately 8 inches of thread.

Step 6: Adjusting Width Adjustment Knob

It is important to set the width adjustment knob to the

correct setting, as this will affect the quality of your stitch.

Your serger is pre-set to the R setting at the factory.

• Disengage upper knife by pulling knife holder to the

right and turning the knob away from you until the

knife is in a horizontal position.

• Using Hex-Head wrench loosen width adjustment

knob by turning to the left, as shown.

• Set the knob to the desired position by moving it

right or left, and then tighten adjustment knob by

turning the Hex-Head wrench to the right.

• The edge of the width finger support plate will line up

with the guidelines on your throat plate as indicated

in the photo.

• When using left and right needle with upper and

lower looper (4-thread) set width adjustment at 4.5

guideline.

• When using left needle and upper and lower looper

(3-thread) set width adjustment at 4.5 guideline.

• When using right needle and upper and lower looper

(3-thread) set width adjustment at 3.5 guideline.

• When doing a 3-thread rolled hem set at R guideline.

Step 7: Threading Tips for the Serger

• Use good quality serger thread. This thread is sold in

larger 3000 yd. spools at most fabric and sewing retailers.

• Use the same brand of thread in all tensions, do not mix

and match brands.

• Use the same size spools on all cone adapters that are

located at the back of the machine when threading your

serger.

• Try to avoid black thread; it tends to cause static, leading

to skipped stitches. Use a dark grey or navy instead. If

you must use black, then thread-up the needles with

black, but use grey or navy in the loopers.
