Things You'll Need
Instructions
Remove the power cord from the outlet that your slot machine is plugged into. Use your key to open the door to the slot machine.
Use a screwdriver to tighten any screws that have come loose. Make sure that there are no loose parts on the inside of the machine. Pull the coin hopper out of the machine and then place it back inside to make sure that it is secure.
Close the door and use a level to find the balance of the unit. Place the level vertically and horizontally to determine what part of the unit is out of balance.
Go to the feet on the machine and use your screwdriver to loosen the screws on the feet. Use the level to make sure that the feet are flat to the ground.
