Bring the ultimate pinnacle of Swiss engineering directly to your creative studio with the magnificent BERNINA L 890 computerized air-threading overlock and coverstitch combo machine. Meticulously designed for passionate garment designers, serious quilters, and professional textile artists, this heavy-duty workhorse delivers unmatched, retail-ready finishing on any fabric style.

Equipped with patented BERNINA innovations like the one-step air threader, a centrally located high-definition color touch screen, and Micro Thread Control (mtc) for edge-stitch uniformity, the L 890 eliminates wave-formation on activewear knits and prevents puckering in fine chiffons.

With a generous workspace, an included slide-on table, and 27 unique utility and decorative stitches, transitioning between overlock, coverstitch, and chainstitch modes is entirely seamless and effortless.

Main Features & Creative Benefits

One-Step BERNINA Air Threader

• Thread loopers instantly with high-efficiency air support
• Step on the foot control to trigger the automated threading blast
• Loopers lock automatically into correct position for a stress-free setup

Forget tedious manual setups forever. The revolutionary BERNINA Air Threader moves looper threads magically through the machine with one simple step on the foot control. Since both of your hands remain free to guide the threads, setting up the machine becomes incredibly fun, fast, and ergonomic.

Intuitive Operation via Touch Screen

• Centrally positioned 4.3 inch Color Touch Screen for optimal views
• Sewing Consultant and Stitch Optimizer recommend best settings
• Switch easily between Guided Mode tutorials and Expert Mode parameters

Access stitch selection, custom parameters, and stitch memories immediately right on the touch screen. Guided Mode offers step-by-step instructions and animations for every setup, while Expert Mode lets advanced sewists apply custom properties directly. Both modes automatically configure tension, stitch length, and differential feeds.

Perfect Seams with Total Stitch Control

• Store up to 100 personalized stitches directly in the personal memory
• Fine-tune cutting width, stitch length, and tension while sewing
• Micro Thread Control dial manages overedge thread quantities seamlessly

Every stitch parameter can be individual adjusted and saved in the L 890's memory library. Seamlessly alter settings while you stitch, and configure the needle stop up or down permanently to accommodate different fabrics, turns, and applique details.

Convenient Features You'll Love

• Raise or lower the needle by exactly a half stitch using foot control
• Free Hand System knee lifter enables hands-free presser foot operation
• Swing-out presser foot design permits convenient, safe needle swaps

Save time and preserve fabric alignments easily. Tap the foot control with your heel to raise or lower the needle by a half stitch. Keep both of your hands securely on fabric layers by lifting the presser foot with the knee lifter, keeping tricky layouts under complete, comfortable control.

Grand Workspace and Freearm Space

• Expansive 5 5/8 inches of space to the right of the needle
• Built-in freearm easily slides child-sized wear, sleeves, and cuffs flat
• Slide-on flatbed extension table adds supreme fabric guidance area

The layout offered on the L 890 is generous by any definition. Boasting more room to the right of the needle and a greater workspace height than any other BERNINA serger model, you can navigate large, bulky quilt blocks and heavy outerwear without bunching or pulling.

Fast, Precise, and Whisper-Quiet

• Stitch at blazing speeds up to 1,350 stitches per minute
• Maintain consistent, strong needle puncture power at any speed
• Program maximum and minimum sewing speeds via touch screen

Whether you are working quickly on straight quilt block sections or driving stitch-by-stitch around delicate curves, the L 890 remains exceptionally quiet. Enjoy flawless overlocking and coverstitching performance at your preferred speed setting.

The Perfect Seam for Every Idea

• Sews using 2, 3, 4, or 5 threads for complete finisher flexibility
• Ideal for highly elastic sportswear knits and loosely woven wovens
• Combine overlock and coverstitches to form extra-durable combination seams

From micro rolled hems on lightweight chiffons to heavy-duty coverstitching on canvas, the L 890 executes flat, retail-standard seams on every textile category. Pair coverstitches and overlock seams simultaneously to construct ultra-strong garments that last.

Quick and Easy One-Path Threading

• Follow direct, color-coded channels to thread loopers and needles
• Transition between coverstitch, overlock, and chainstitch modes in seconds
• Interactive help animation on touch screen walks through every step

No more serger setup hesitation. Color-coded lay-in paths allow threads to slide naturally into their designated channels, making mode alterations quick, reliable, and completely intuitive.
