Plan how you are going to get this thing (heavy, bulky, hard to hold on to) into its final position (first floor, basement, attic). You may need to remove handrails, doors, loose rugs and other things in the way. Watch unboxing videos. You may choose to unbox and then do the final move. Get lots of help, make sure they are able to lift a lot of weight. You will need wrenches or a socket set. Clean your balls with isopropyl alcohol (may tingle a bit). Check playfield for loose posts, ramps, parts, etc. Check under playfield for any loose wires or parts. There may be shipping blocks on playfield and underplayfield parts that need to be removed before the first game.
TL;DR Lots of help, go slow, read the instructions.
