What I like to do when I set up a new game.
Get it set up. Remove the playfield glass. Look over the bottom of playfield and inside the back box for any connectors or anything else loose from shipping. Install the two big wing nuts to hold the head down.
Lower playfield. Quick clean easy to reach areas and a coat of a good wax. Clean balls and install. Get the game in position. Set playfield to 6 1/2 degrees, level left to right, front and rear. Put glass back on.
Turn the game on. Set any adjustments or anything I like. Start playing.
