Presser Feet BERNINA Presser Feet: ▪ are precision engineered for specific functions ▪ are Swiss-made for the highest quality ▪ are one-piece metal feet, making them sturdy and durable ▪ are easy to change with one hand, requiring no special tools ▪ have a white shank, making it easier to see the eye of the needle, resulting in easier threading ▪ are, in some cases, modeled after commercial feet used in factories to increase speed and production with professional results ▪ do the job intended in relation to all types of sewing (example, quilting, garment-making, home dec, etc.) ▪ are supported by the best and most complete educational materials in the industry, such as Feet-ures volumes 1, 2, & 3, and the BERNINA of America website at www.berninausa.com Understanding the Numbers/Letters BERNINA presser feet are numbered and may have one or two additional versions with a letter that follows the number, such as Edgestitch Foot #10C or Jeans Foot #8D. Number Only-The number without a letter refers to a foot engineered for BERNINA models that have a CB Hook and a maximum stitch width of 5.5mm. These feet may also be compatible with models that have a 9mm width when a 9mm width is not desired, such as when making pintucks with feet #30, 31, 32, or 33. The Letter "C"-When a foot number is followed by a "C", it indicates a version of the foot made for models that have rotary hook systems and a maximum stitch width of 9mm. The "C" stands for coded and refers to the sensor on the foot that works with the electronics of the machine to engage the wider stitch width. The sole of the "C" foot is usually larger to fit the wider feed dog of the rotary hook machines. Exceptions: Overlock Foot #2/2A: 2A is larger to fit the wider feed dog but does not have a sensor for a wider stitch because the overlock stitches are not used at wide widths. Extra Wide Gathering Foot #16C: 16C is larger to fit the wider feed dog but does not have a sensor for a wider stitch width. The Letter "D"-The feet that have a number followed by a "D" are designed to work with the 8-Series (models 830 and 820) Dual Feed feature. After attaching the foot, the Dual Feed mechanism is positioned in the cutout on the back of the foot, engaging the BERNINA Dual Feed system. It is recommended that the D-Feet be used only when the BERNINA Dual Feed Feature is engaged. Easy-On/Easy-Off Soles-The 3 Series & activa machines have simple-to-use easy-on/easy-off metal soles that attach to a standard shank. These machines are also compatible with the one-piece full-shank presser feet available as optional accessories for all BERNINA machines.
