rotary cutter
I have 2 rotary cutters. The blades do not turn. I have taken the cutters apart and re-installed the blades numerous times. My husband even tried. We have loosened the nut holding the blade on and tightened it. I can't get them to turn. One cutter is an Olfa. I don't know the brand of the other one. Should they be oiled? Have you ever had this problem? What should I do? Thanks.
