If you need to temporarily prevent use of your toy crane machine, whether for maintenance, relocation, or to control unsupervised play, several secure methods are available. The most straightforward approach is to disconnect the power source. Simply unplug the machine from the electrical outlet. For added security, locate the internal power switch, often found near the power cord entry point or on the power supply unit inside the cabinet, and turn it to the "Off" position.

For a physical lockout, consider securing the coin mechanism. Many machines have a built-in lock on the coin door. Use the existing key to lock it. If the key is lost, a small padlock can often be threaded through the coin slot or a hasp to prevent coin insertion. Alternatively, you can place a clear, prominent "Out of Order" sign over the controls to deter users.

For long-term storage or transport, accessing the main control board allows you to disable the machine completely. This typically involves disconnecting a key wiring harness or fuse. Please refer to your machine's manual for specific instructions, as improper handling can cause damage. Always ensure the machine is unplugged before attempting any internal access. Implementing these measures will effectively lock your toy crane machine, ensuring safety and preventing unauthorized operation until you are ready to resume normal use.
