Which safety devices should be checked before operating the TLB?

Before operating a Tractor-Loader-Backhoe (TLB), it is crucial to ensure that safety devices are in proper working order to maintain operator safety and ensure compliance with industry regulations. The reverse warning alarm is essential as it alerts anyone in proximity that the machine is backing up, thus preventing accidents and injuries. The seat belt is equally important as it keeps the operator securely in their seat during operation, especially in the event of sudden stops or movements.

While the emergency brake and headlights are important for safe operation, and checking fuel levels and tire pressure contributes to the overall function and maintenance of the machine, they do not specifically address immediate safety concerns in the context of operator protection and hazard awareness. Blade height and side mirrors are more related to operational efficiency and visibility rather than directly to safety apparatus that demand checks before use. Therefore, focusing on the reverse warning alarm and the seat belt encapsulates the key safety measures necessary to minimize risk before starting the TLB.
