Hello, Kenx12 - We are sorry that you're having trouble with this kit! The guide post is designed to fit just inside the 1-inch pre-drilled hole snugly. This allows our customers to score the tool in the correct spot on the door and eliminate the chance of the tool moving. And the manual image is meant to reinforce the idea that the guide post does go into the pre-drilled hole. We hope this helps, but if it doesn't then please contact us at Reviews@RYOBItools.com.
