If you look below the big wheel there is a lever about 6 inches long that reaches over to lever on the small wheel. Once the big wheel counts out the coins to go into the jackpot that longer lever is then lifted to make contact with the small lever below the small wheel. Once the two levers ends come in contact with each other the coins will no longer go in to jackpot.
Hope that helps you. I have my big wheel set at 100 coins.
