Singer BAJ3 8. Loud hum
I just changed the belt on my Singer BAJ3 8 and now I have a loud hum that seems to be coming from the motor when using it. I don't have the manual for this and am stumped as to why it now hums. I tried loosening the belt , but no luck..Also , I really had to struggle with getting the belt on..very tight.
Any suggestions.......Tks. Greg
