Quoted from SantaEatsCheese:New to owning pinball machines... is this something you normally do through the coin door or do you usually have to remove the glass?
you remove the glass, open the door and use your finger to push on the solenoid and eject the balls.
you don't necessarily have to raise the playfield if you don't want to. (you can access through the coin door)
you take the balls out because you don't want them banging around during transport and breaking stuff.
