What steps do I need to follow to bolt my safe to a concrete floor?

Open the safe door and remove the four black caps on the safe floor to access the bolt-down holes. Drill pilot holes in the concrete, insert plastic anchoring plugs, then thread all 4 anchor bolts through the factory-drilled holes and tighten securely. Ensure the metal washer sits on top of the rubber washer and tighten the bolt to compress the rubber washer—failure to do so will allow water to enter during a flood. Finally, replace the four black caps.
