When the stacker starting switch is turned for the first time, which meter display should not light up?

The correct response indicates that when the stacker starting switch is activated for the first time, the meter display that should not light up is the one resembling a hamburger. This is likely an indicator related to some auxiliary function or operational setting not directly related to the primary operation of the stacker at the moment of startup.

When the stacker is powered on, critical indicators related to the machine's immediate operational status, such as the pressure gauge, battery indicator, and oil temperature, are designed to provide essential information about the system's readiness, battery charge, and hydraulic fluid temperature. These gauges are crucial because they help operators assess whether the stacker is safe to use and if all systems are functioning correctly.

In contrast, the meter that looks like a hamburger may represent a non-essential function or feature of the forklift, such as a display for optional features or less critical information. Since many of these advanced features may not be activated or relevant until certain conditions are met, it is expected that this particular gauge does not illuminate during the initial power-up phase, focusing instead on critical operational indicators.
