What safety feature should always be checked before operating a telehandler?

Before operating a telehandler, it is essential to ensure that all safety features and important operational parameters are thoroughly checked. Each of the listed options plays a critical role in ensuring safe operation.

Checking the fuel level is vital because it prevents running out of fuel during operation, which could lead to unexpected stops and potentially hazardous situations.

Adjusting the operator seat is also crucial, as proper seat positioning directly impacts control and comfort while operating the machine, thereby affecting the operator's ability to respond effectively to any situation that may arise.

Inspecting for hydraulic fluid leaks is equally important because hydraulic systems are essential for the telehandler's operation. Leaks can lead to loss of hydraulic pressure, resulting in equipment malfunction and posing serious safety risks.

By recognizing that all these checks are important components of a comprehensive safety protocol, the correct answer encompasses the necessity for a holistic approach to safety checks before utilizing the telehandler. This ensures that every aspect of safe operation is accounted for, promoting a safer working environment.
