It's in the yard, I have it for four hours, and a friend came and helped me offload it from the SUV. I think we put a little hole in the headliner, I'll mend that later. When we put it back it will go on it's side or my friend will put it on his trailer and return it.

Electric cord, leather gloves, safety goggles, and I've watched a video about how to install the various tools. I downloaded a PDF of the instruction manual specific to this machine and that helps even more. And this is what I was looking for:

Continue to automatically feed cable until obstruction is met. When cable begins to drag or rotation becomes difficult, move the lever to the neutral position and allow tool to cut away at the obstruction. I hope this is as easily done as the guy in the tool rental department said it is.
