What should an operator do before starting a backhoe loader?

Conducting a pre-operation inspection is essential for ensuring the safety and efficiency of equipment like a backhoe loader. This process typically involves systematically checking various components of the machine, including fluid levels, hydraulic systems, lights, brakes, and the overall condition of the tires and undercarriage.

By performing this inspection, the operator can identify any potential issues before they result in malfunction or safety hazards during operation. For example, checking the hydraulic fluid levels can prevent equipment failure, while ensuring that safety features like lights are functioning properly helps to avoid accidents during use. This proactive measure not only protects the operator and others on site but also reduces the likelihood of costly repairs and downtime.

The other options do not adequately ensure the machine's safety and functionality. Ignoring the need for inspection based on engine sound could lead to overlooking critical issues. Simply turning on the engine to check for leaks is insufficient, as it does not cover the comprehensive assessment needed before operating the machine. Cleaning the cab, while important for operator comfort, does not address the essential operational checks required for safe and efficient machine use.
