2-Thread Flatlock ......................22 Color-Coded Threading Charts ................... 23 1150MDA Basic Serger Use 800DL 1300MDC 700D The information in this workbook applies to the current line of BERNINA Sergers. Note: Some exercises apply only to certain models equipped with the feature being highlighted.
Sometimes called the microwave of sewing, your serger will speed your sewing in several ways, letting you produce more in less time. The speed of the serger is faster than a sewing machine and because it performs several operations (trimming, seaming, and overcasting) at the same time, you sew faster, and in the process, produce neater and more professional-looking results.
You also want a good-quality thread – such as Mettler Metrocor – that is not “fuzzy” and does not leave excessive lint in the lower part of your overlock machine. Serger threads are sold on cones for economy and convenience; regular spools of thread may be used but will not last very long when forming serger stitches.
Presser Foot: 4-thread overlock Stitch: Thread the serger for a 4 thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings as indicated below. Fold the fabric in half to 3” x 6”.
Adjusting Tension Settings Examine your 4-thread sample. The illustrations below show examples of unbalanced stitches and how to correct the settings to balance the stitch. When making corrections in the tension settings, increase or decrease the settings as needed, moving the dial ½ to 1 number at a time. Stitch a seam using the new settings and then evaluate the new stitch.
Divide the fabric into 4 equal sections along one side, finger-press the folds to form creases. Thread the serger for a 4-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings as indicated below.
Using a fabric marker, divide the fabric into four equal sections along the folded edge. Thread the serger for a 4-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings as indicated below.
Divide and mark the fabric into three equal sections along the folded edge. Thread the serger for a 4-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings as indicated below.
Differential Feed: Stretchy Fabrics Knit ribbing, three pieces, 3” x 6” each Fabric: 80/12 Universal Needle: 4 cones of serger thread (blue, red, green, yellow) Thread: Standard Presser Foot: 4-thread overlock Stitch: Thread the serger for a 4-thread overlock stitch using thread colors to match the color-coded threading path on the serger.
Presser Foot: 4-thread overlock Stitch: Thread the serger for a 4-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings as indicated below. With differential set at N, serge on one 6” edge. If fabric is lightweight enough you will have a puckered edge.

Using a fabric marker, divide the fabric into 3 equal sections along the 12” side. Thread the serger for a 4-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings as indicated below.
Place the fabric under the presser foot so that the first stitch will enter the fabric when you begin stitching. Slide the Stitch Selection lever towards the body of the serger. Serge for about 1”, overstitching the previous stitching. Guide the fabric so as not to cut the previous stitching.
Presser Foot: 4-thread overlock Stitch: Thread the serger for a 4-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings as indicated below. Locate the tape guide on the presser foot.
Snug the needle set screw after removing the needle. Thread the serger for a wide 3-thread overlock stitch using the LEFT needle and thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings for a balanced stitch as indicated below.
Using the small screwdriver and brush/needle insertion tool, remove the left needle. Snug the needle set screw after removing the needle. Thread the serger for a narrow 3-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings for a balanced stitch as indicated below.
Using the small screwdriver and brush/needle insertion tool, remove the left needle. Snug the needle set screw after removing the needle. Thread the serger for a narrow 3-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings for a balanced stitch as indicated below.
Thread the serger for a narrow 3-thread overlock stitch using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings for a rolled edge as indicated below. Pull the Stitch Selection Lever toward you.
Snug the needle set screw after removing the needle. Thread serger for a wide 3-thread flatlock stitch. Adjust all thread tension settings as indicated below. Note: Sample was stitched with regular thread but a heavy thread such as YLI Jeans Stitch or Designer 6 can be used in the upper looper for a more decorative look.
Note: This is an optional accessory for the 700D. Thread the serger for a 2-thread using thread colors to match the color-coded threading path on the serger. Adjust all thread tension settings as indicated below. Pull the Stitch Selection lever toward you.
Attach the Upper Looper Converter to the upper looper. Note: This is an optional accessory for the 700D. Thread serger for a wide 2-thread flatlock stitch using thread colors to match the color-coded thread paths on the serger. Adjust all thread tension settings as indicated below. Note:...
