What causes starving of a hydraulic system?

Starving of a hydraulic system occurs when there isn't enough hydraulic fluid reaching the components that require it, leading to insufficient lubrication and power. This can result in various performance issues and even potential damage to the system. The factors listed in the correct choice directly contribute to this situation.

Low fluid levels reduce the amount of hydraulic fluid available for circulation, which can lead to starvation. A dirty filter can block the flow of fluid, restricting the amount that can reach the hydraulic components. Similarly, leaks in hoses or fittings allow fluid to escape the system before it can perform its intended function. Kinked hoses can obstruct the flow of fluid, further exacerbating the issue by preventing necessary hydraulic pressure from being maintained. All of these factors collectively impede the system's ability to function effectively, leading to a condition known as starving.

In contrast, while overheating can affect hydraulic systems adversely, it does not directly relate to the concept of starving a system. Excess fluid might cause other problems, such as spills or pressure issues, but would not typically cause starvation. Using an incorrect fluid type can lead to system malfunctions but is less directly associated with starvation compared to the specific issues presented in the correct choice.
