Hey guys, just a quick question: I've got a babylock design pro sewing machine---bought it new 3 years ago. I've never had it serviced, but its worked really well for me. My question is......on a new style sewing machine, do you have to lubricate the bearings in the moter? I oil the machine pretty often, but its been making a whining sound lately. Just wondering if anyone else has done any mtc on their thread injector!
