My baby lock bl5260 serger starts ok but slows down and then stops

I have the same problem and the same model. Had it serviced and still have this problem. I also have a strange smell inside mine. maybe something with the motor or something else. I purchased this machine and took out the foot to thread it and now my feed dog dropped down and I do not see a lever to raise the feed dog. Will look again tomorrow or when I have time.

If it is a mechanical machine (not computerized), it could be seizing due to old oil that has dried. Mechanical machines, especially sergers, need frequent and thorough oiling (interior moving parts) using a good quality sewing machine oil. Avoid trying to run the macchine until you can get it serviced or the motor could be damaged.
