Aside from safety gear, any special tips with using one of these? I'll be renting the roto hammer.

I'll be drilling holes in 2'x2'x6" pads for a pad/post cabin setup to secure RR ties to them. I know I'll need some masonry epoxy to hold my anchors in place; anything else to consider?

I'll be using bits for cutting rebar, as the pads will already have reinforcement in them.
