I'm in SoCal so my schedule may or may not be right for you. I paste wax my machines about twice a year when doing regular maintenance; oiling rollers, greasing threads, checking nuts and bolts for torque, etc. It's usually one day of an annoying lube-fest. I will on-the-spot wax machine surfaces that are not nice and slick. You don't want to have to shove your material through the cutters.
