Explanation: The primary purpose of a telehandler's Load Moment Indicator (LMI) or Load Indicator system is to ensure safe operation by alerting the operator when the machine is approaching or exceeding its safe working load limits. This system helps prevent overloading and potential instability, which could lead to accidents. It constantly monitors the load and the machine's configuration.

Explanation: If the Load Indicator system displays an overload warning, the operator must immediately cease operations that increase the load moment and take corrective action. This typically involves lowering the boom and retracting the load to a safer position, or reducing the load itself. Continuing to operate while overloaded significantly increases the risk of instability and overturning.

Explanation: The Load Indicator system is specifically designed to monitor the load on the telehandler and its configuration. An audible alarm is typically activated when the machine is approaching or has exceeded its safe working load limits or rated capacity. This is a critical safety warning to prevent overturning or structural damage.

Explanation: As part of a pre-shift inspection, an operator should always ensure that the Load Indicator system powers on, the display is functional, and that it successfully completes its self-test sequence. This confirms the system is operational and can provide critical safety information during the shift. If it fails to power on or shows errors, it must be reported.

Explanation: While a Load Indicator provides real-time data on load and outreach, it's crucial for the operator to know the actual weight of the load. This allows the operator to cross-reference with the machine's load chart and the LMI readings to ensure the load is within the safe working limits for the specific configuration. Relying solely on the LMI without prior knowledge of the load could lead to misjudgment, especially if the LMI malfunctions or if the load's center of gravity is unusual.

Explanation: A typical telehandler Load Indicator display is designed to provide critical operational data related to stability and load. This includes the current boom angle, the horizontal outreach of the load from the front wheels, and the actual weight of the load being lifted, often expressed as a percentage of the machine's rated capacity for that configuration. This information allows the operator to stay within safe operating parameters.

Explanation: A functioning Load Indicator system is a critical safety device. If it malfunctions, showing incorrect or no readings, the telehandler can no longer be safely operated, as the operator cannot accurately assess the load and stability risks. The operator must immediately stop operations, safely lower any suspended load, and report the fault to supervision. The machine should not be used until repaired.

Explanation: Different attachments significantly change a telehandler's centre of gravity, leverage, and overall lifting capacity. Modern Load Indicator systems require the operator to select the correct attachment type. This input allows the system to apply the appropriate load chart and stability parameters, ensuring accurate warnings and preventing overloading specific to that attachment. Failure to select the correct attachment can lead to inaccurate capacity calculations and unsafe operation.

Explanation: The Load Indicator system electronically interprets and displays real-time data based on the machine's specific load chart. It translates the information from the load chart into dynamic warnings and displays for the operator. The physical load chart should always be consulted by the operator for verification and understanding the machine's capabilities, acting as a critical reference alongside the LMI. They work together to ensure safety.

Explanation: Correct calibration of the Load Indicator system is absolutely crucial for its accuracy and reliability. An uncalibrated system could provide misleading information, either triggering false alarms (inefficient) or, much more dangerously, failing to warn the operator when the machine is actually overloaded. This could lead to serious accidents, making accurate calibration a cornerstone of safe telehandler operation.
