Leveling a toy crane machine on an uneven floor is crucial for fair gameplay and machine longevity. An unlevel crane can cause prizes to slide unfairly and strain the machine's mechanics. The best method involves a systematic approach. First, use a high-quality bubble level placed on the prize chute or the main deck. Identify the low corners. For permanent or semi-permanent setups, the most effective solution is to use plastic or metal leveling shims or wedges. Gently lift the machine's cabinet at the low point and slide the shims under the leg or base until the bubble is centered. For machines with adjustable feet, simply turn the feet clockwise to lower or counter-clockwise to raise that corner. Recheck the level from multiple angles. Test the crane's movement and claw drop to ensure smooth operation. Avoid using unstable materials like wood or cardboard, which can compress. Regularly recheck the level, especially after moving the machine, to maintain optimal performance and player satisfaction.
