I have mine set on Factory which will give you the option of dropping the shifter and hitting the fire button on the Orange moon. You can check which setting you have your game on by going into the game adjustments.
Inside the coin door the green button should be out and then scroll through using the black button until you get to adjustment 7. You will scroll through the Audits first so don't confuse audit 7 with adjustment 7. Once your on Adjustment 7, use the Start button to scroll though to Factory.
Page 15 of the manual has the adjustment details if you have it. If not you can down load here.
