Here is a video of stitch formation on BabyLock 838D serger, without the presser foot.
BabyLock 838D stitch formation
The BL4 838D DOES sew a regular 4 thread overlock stitch, so that is the only difference, between the instructions, and stitches, for these 2 sergers, except the 838D has a built in upper looper converter, that is turned, using a flathead screwdriver, to block the upper looper, when you want to sew a 2 thread overlock stitch, and the 428 has a separate converter wire.
DIFFERENTIAL FEED - create ruffles or prevent knits from stretching while sewing! Want to sew a gorgeous decorative lettuce edge quickly, on stretch fabrics, or bias woven fabrics? It takes seconds with the BL4-838D !
Easy to adjust differential feed while sewing, with lever on the side of the machine.
Snap on presser foot is easy to change to other specialty presser feet in seconds.
Built in ribbon & elastic guide in the toe of the presser foot that comes with the machine new.
Calibrated tension makes it possible to make a huge variety of stitches & effects, & if you keep a workbook, write down which setting each tension was set at, with the stitch width, length, & differential feed settings, along with a stitch sample showing the stitch you made, makes it easy to repeat that stitch the next time you want the same effect.
High quality, well built metal machine, will outlast lighter weight plastic machines. Very few plastic parts on this model.

| Stitch Length is adjusted by turning the hand knob until you see the green line, on the right side of the machine, lining up, & then you push in this dark silver knob in the little "window", & turn the handwheel until the correct stitch length you want, shows in the window on the front of the serger. |

BABYLOCK SERGER REPAIR INFORMATION-
ISSUE- serger slows down, as it warms up, handwheel becomes hard to turn. There is a known issue with the Babylock ProLine sergers, including some of the 838D, may eventually have an issue with the machine sewing, but slowing down, as it heats up. There was a recall of the stitch length ECCENTRIC (cam?), on the serger, the metal becomes rough over time, due to being made of 2 different metals, so it has to be removed, polished, and replaced, and will continue to work. I am including a link to another blog, which has the instructions and photos, to assist you in this repair. (Neither of my 838D sergers has had this issue. I sold my first 838D after buying the air threaded BabyLock sergers, but I really love the mostly metal 838D, and decided to get another one, especially with the knee lift. I usually own several sergers and sewing machines at a time, since I enjoy learning them, fixing them up, and blogging about them.) Babylock Serger slows down hard to turn handwheel repair info

Here is a link to a blog post about timing a serger, very hard information to find, online.

| Comment explains how BabyLock Pro sergers can require the STITCH LENGTH ECCENTRIC CAM to be removed, polished smooth with emery cloth (also polish the bushing they fit inside), then replace and oil it, you may need to retime loopers afterwards. The clue this needs done, is serger slows down, as it warms up, or feed dogs stop working. Easy fix! |
