yes you can bypass like the video shows to test it. It's illegal to operate it that way because people have lost limbs and be otherwise seriously hurt reaching in while still spinning.
reminds me of a story a guys was telling me once about tearing someones ear off.
I said, "really you tore it off, how?
He said, "Well just think about it, it's just a piece of skin with grissle, the grissle gives ya some to hold onto better. So ya just grab it toward the top half, twist, then rip downward. Comes right off!"
I'm thinking shit, why do people tell me things like this, I really don't want to know it!
Better listen to Bigbuck and get the switch:
