Hello! I bought an Universal World Series of Slots bandit for almost nothing because it was stone dead. But after several hours i have got everything to work except playing with the handle! I insert coins and the handle solenoid is activated and i can pull the handle and the reels spins as they should, but then the handle get stuck in the down position and i cant get it back. ( I have to release it mechanically inside the machine) What can be wrong? It has nothing to do with lubrication because the handlemechanic is well lubricated. Please help.
