I look over inside the game, cabinet and back box. Anything loose, connectors or assemblies ?
Then I clean and wax the easy to get to areas.
Then set in place and level and set the pitch of the game. Install the plumb bob tilt and center it and set it where I want it.
Clean the balls and install them.
Power up and let 'er rip ! Make any game adjustments you want.
Then invite all of Pinside over to party.
