One-Step BERNINA Air Threader
The illuminated One-Step BERNINA Air Threader makes looper threading faster and easier.
Insert the thread, press the control and let the machine guide the looper threads into place. The illuminated threading area and color-coded threading path help make setup easier to see and follow.
A built-in needle threader also helps reduce the time spent preparing the machine.
Comfortable Hands-Free Control
The BERNINA Free Hand System lets you raise and lower the presser foot with the knee lifter while simultaneously lowering the feed dog.
This keeps both hands free to guide, position or remove the fabric.
The swing-out presser foot provides easier access to the needles, while the two-step presser foot lift gives you extra room for thick fabrics and layered projects.
Total Stitch Control
The L 660 gives you precise control over how each stitch looks and performs.
Micro Thread Control
BERNINA Micro Thread Control lets you fine-tune the amount of looper thread along the fabric edge.
You can make adjustments while sewing to create smooth, balanced seams and polished edge finishes.
Differential Feed
The adjustable differential feed helps prevent puckering on fine fabrics and unwanted stretching on knits.
It can also be used to create gathering and other decorative effects.
Adjustable Presser Foot Pressure
Change the presser foot pressure based on the thickness and type of fabric you are sewing.
Control the Machine Your Way
The programmable BERNINA foot control allows you to sew slowly, stitch by stitch or at higher speeds.
Use the back-kick function to raise or lower the needle. You can also program the needle to stop in the up or down position.
A front-mounted speed control lets you choose the sewing speed that feels comfortable for the project.
Fast, Smooth and Quiet
The powerful DC motor delivers smooth operation at speeds of up to 1,200 stitches per minute.
The L 660 gives you the speed needed for longer seams while still allowing precise control around curves, corners and detailed areas.
Adjustable Cutting and Stitch Width
The cutting knife can be engaged or disengaged from the outside of the machine.
This makes it easy to switch between trimming and sewing without cutting the fabric.
The stitch width can be adjusted from 3 mm to 9 mm to suit different fabrics, seams and finishes.
Bright, Organized Work Area
The spacious sewing area gives you room to guide both smaller pieces and larger projects.
The included slide-on table expands the work surface, while the dimmable sewing light helps improve visibility.
A magnetic tool holder keeps frequently used tools close at hand, and the accessory box provides organized storage.
