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.
