Frequently Asked Questions

What does 'used less than 1 month' mean for this machine?

This bernette 62 AIRLOCK was purchased by a customer who returned it after using it for less than one month — not because of any defect, but because they changed their mind. The machine is in like-new condition, comes in the original box with all original accessories, and carries the full bernette manufacturer warranty. OSP Machines has inspected it and confirmed it is complete and fully functional.

What is included in the bonus package?

The bonus package includes a Tutto Serger Trolley (for easy transport and storage), 16 spools of Mettler Seracord serger thread in white, ash mist, black, and muslin (4 spools of each color), two packs of Schmetz serger needles in size 12/80, and two packs in size 14/90. The total bonus value is over $300.

What is the warranty on this machine?

bernette backs this machine with a 10-year mechanical parts, 2-year circuit board, 2-year electrical, and 1-year labor warranty. Because this is an open-box unit, the warranty period begins from the original purchase date. OSP Machines is an authorized bernette dealer, and your warranty is fully valid and registered through bernette.

What is the difference between the bernette 62 and the bernette 42 (B42)?

The bernette 62 is a significantly larger machine than the bernette 42 and is purpose-built as bernette's top-of-the-line coverstitch and chainstitch machine. The 62 offers four coverstitch configurations and three chainstitch options, along with the AIRLOCK automatic air threading system not found on the 42. If you need maximum flexibility in coverstitch and chainstitch work from a single machine, the 62 is the more capable choice.

Is this machine suitable for a beginner?

The bernette 62 AIRLOCK is best suited for sewists with some sewing experience — particularly those who work regularly with knit fabrics, activewear, or garments requiring professional seam finishes. The air threading system makes looper threading much easier than on traditional sergers, which lowers the barrier to entry. That said, coverstitch machines have a learning curve, and this machine will be most rewarding for sewists at an intermediate level or above.
