Every time I use a 6" solid orange foam pad with the forced rotation engaged the pad feels very grabby and the machine wants to 'walk'. I have primed the pad, put on what seems to be enough product (Sure-Finish), and I am trying to keep the pad flat against the surface. I have the speed set at 3, but I'm not sure if that's correct. The machine seems harder to control than it should be -- or is it just not enough muscle on my part? Any suggestions?
