| Short operating time. | Battery not fully charged; old or worn-out battery. | Ensure battery is fully charged before use. Consider replacing the battery if it's old. |
| Interference during operation. | Operating near other 2.4GHz devices; too far from remote. | Move to an area with less interference; ensure excavator is within remote control range. |
