When conducting an inspection of the hydraulic system in an excavator, it is crucial to identify defects that could lead to operational failures or safety hazards. Oil leaks, fractures or bulges in hoses, and loose connections are critical aspects of the hydraulic system that must be monitored regularly.

Oil leaks can indicate a failure in the hydraulic lines or seals, which directly impacts the integrity and efficiency of the hydraulic system. Fractures or bulges in hoses signify wear and tear that could lead to catastrophic system failures if not addressed. Loose connections may result in hydraulic fluid escaping or system pressure loss, which can severely affect the machine’s performance.

Excessive color fading, while it may suggest other forms of wear or exposure to environmental factors, does not directly impact the hydraulic functionality of the system. It is more an aesthetic concern than a fault that would impair the operational safety or effectiveness of hydraulic systems. Therefore, it is not considered a defect that needs to be addressed during hydraulic system inspections.
