Which of the following is a common maintenance task for graders?

Inspecting hydraulic fluid levels is a critical maintenance task for graders because the hydraulic system is essential for their operation. The hydraulic system controls the movement and function of the grader's blade, steering, and other attachments. Regularly checking fluid levels ensures that the system operates efficiently and prevents potential failures due to low fluid, which can lead to performance issues or even accidents.

Monitoring hydraulic fluid levels allows operators to identify leaks or degradation of fluid early, which is vital for the longevity of the machine. Proper fluid levels ensure smooth operation and help maintain the effectiveness of hydraulic components. Therefore, engaging in this inspection regularly is a proactive approach to maintenance that supports both safety and equipment reliability.

Other maintenance tasks, although important, may not be as frequently necessary or critical to immediate operation as inspecting hydraulic fluid levels.
