Didn't mention earlier, but it may need cleaning ....... the blades come with a bit of oil on them, and with continual use, they can collect "gunk" and get all gummy and such inside the assembly. I keep alcohol swabs in my sewing room, and will wipe the gunk clean, add the extra drop of oil and put it all back together again.
