What is the most important check to perform on the hydraulic system?

Inspecting for leaks in the hydraulic system is essential because leaks can lead to a loss of hydraulic fluid, which is critical for the system's operation. If the hydraulic fluid is leaking, not only can it impair the function of the dumper, but it can also pose safety hazards, such as the risk of hydraulic failure while operating the equipment. Additionally, leaks may lead to environmental concerns due to fluid spillage. Ensuring that the hydraulic system is secure and free from leaks is vital for maintaining operational efficiency and safety in their day-to-day activities.

Checking the hydraulic oil color, ensuring proper tire pressure, and testing the lift height, while important for overall vehicle maintenance, do not directly address the integrity and functionality of the hydraulic system. While monitoring fluid color can indicate contamination, it does not provide immediate information about leaks which can jeopardize performance and safety.
