Frequently Asked Questions
-
Q: Can the Brother 2340CV cut fabric fabric edge like a regular serger?
A: No, this is a dedicated cover stitch machine designed purely for hemming, binding, and decorative topstitching. It does not feature a cutting knife. It is built to complement a traditional serger or sewing machine.
-
Q: What type of needles does this machine use?
A: The 2340CV uses standard household sewing machine needles (System 130/705H). For best results on knit or stretch fabrics, we highly recommend using ballpoint or stretch needles.
-
Q: Is it difficult to convert the machine from a 3-needle setup to a 2-needle setup?
A: Not at all. To change stitch configurations, you simply use the included hexagonal wrench to remove the needle you do not need, and unthread the corresponding line.
-
Q: Can this machine perform a standard chain stitch?
A: Yes, by utilizing two threads (one needle and the lower looper), you can create a highly durable and flexible utility chain stitch that is ideal for construction or basting.
