The drill comes without instructions. In the beginning it was difficult for me to switch from one stamp size to another. There is a bolt on the selector that holds the lever in place, I loosened it and it was easier to turn it about half a turn before it tightened again. The hole he punches is not a clean hole. It's ripped and won't even go through 2 layers of vinyl. I'll return this beat if I can as it's definitely not working for me.
