Resetting Timing Babylock BL3-408 Serger

Threaded View
Hello, all. I bought a Babylock serger on craigslist and it worked
perfectly. Unfortunately, I was rough on it and it jammed. I couldn't even
get the fabric out to look at it. My upper looper broke so I bought a new
one. It still kept getting caught on the lower looper so I moved it, too.
Obviously, I need to reset the timing. I have been at it for hours. It's
been almost three months since I put the new upper looper on. First, I
couldn't get the subsidiary looper into the hole of the upper looper. Now
I have the upper and subsidiary loopers in synch and I thought the lower
looper was in synch as well because it will form a chain... until I put
fabric in. Then, it only knots a couple of times every few inches then
goes back to forming chains without fabric again. The chain looks... odd.
Like the loops are too big from one thread. I'm at wits end. I don't know
if I should keep fiddling with the timing or if I should try the tention
settings. There are no numbers on tention settings so this is very
difficult since I'm completely self taught on this thing. Thanks so much
to anyone who can help!

Probably shouldn't have done that. You may have only needed to adjust the
upper looper to increase its distance from the lower looper.

Your best bet is to take it to a service technician. If you have a sewing
machine timing gauge, you can use it to set proper timing between the
lower looper and left needle by adjusting the position of the cam that
drives the lower looper. That will give you a good starting point for
adjusting the upper looper. There are probably burrs on the lower looper,
needle plate and needle guard(s) that will need to be found and smoothed
before it will stitch properly.
