What are some signs of equipment malfunction in a telehandler?

The presence of unusual noises, fluid leaks, and warning lights are clear indicators of potential equipment malfunction in a telehandler. Unusual noises can suggest mechanical issues, such as wear or damage to bearings or gears, while fluid leaks may indicate problems such as broken seals or hoses that could lead to more serious operational failures. Warning lights typically indicate that the telehandler's onboard diagnostics have detected an issue that requires attention. Monitoring these signs is crucial for maintaining safety and ensuring the equipment operates effectively.

In contrast, high fuel consumption and increased speed might not directly reflect a malfunction; they could result from operator behavior or load conditions. Extended operating hours without rest may indicate excessive usage, but it does not inherently signify a malfunction. Improved lifting capacity signals would suggest better performance rather than pointing to a malfunction, which can lead to complacency if performance is misinterpreted. Each of these other options lacks the clear correlation with internal equipment issues that the correct choice demonstrates.
