Question about PfaFF Hobby 4260
Having trouble keeping the lower loopers threaded on the Hobbylock 776 that came to me recently. Has been serviced and sews perfectly sometimes. How can I solve the problem?

The best I can say is to change all your threads to different colors and get light colored material. Start with tenstion for all set to N - normal and experiment from there. Change one thread's tension at a time, sew a long strip and check out both sides and adjust as needed. Remember to start with new serger needles and a oiled machine. I'm not an expert - I just have had a serger for 15 years.

Try replacing the needle. It may be bent. I use polyester/cotton thread in the bobbin as it is stronger and resists breaking. A loose or a tight adjustment on the bobbin holder can also cause breaking. Check with a service shop for this one if you are not familiar.

Been there, done that. Old serger almost went out the window more than once.
Raise the thread antenna and loopers to their highest positions.
Set the tensions to zero. If your serger has auto-tension, raise the presser foot as this also opens the tensions.
Begin threading from the right as indicated in your manual or on the door of the serger.
If this continues, the serger may need to be serviced as the timing could be the problem.
Ask before leaving the serger as the service cost usually starts around $100.
I finally gave in and bought a Babylock with instant jet-air threading.

Here is the trick: If you look at your thread spools, left to right, thread machine beginning with thread from spool 3, then 4, then 1, then 2.
Thread 4 is tricky. You must line up the purple line on the big wheel on the right end in order to do this. Thread the machine according to the diagram on the inside, then, making sure you lined up the purple line, push the lever at the bottom of the machine (below threading guides) to the left while holding on to the thread end. This will push the thread up and along the horizontal arm you just threaded.
