Inspecting the hydraulic hoses weekly is crucial for the proper functioning and safety of a road grader. Hydraulic systems rely on high-pressure fluid to operate various components, and any leaks or wear in the hydraulic hoses can lead to system failure or diminished performance. Regular checks can help identify any signs of abrasion, cracking, or bulging in the hoses, which could indicate impending failure or the potential for leaks.

Hydraulic hose inspection is important not just for maintaining the machine's efficiency but also for ensuring operator safety. If a hose were to burst while the machine is in operation, it could lead to a hazardous situation. Therefore, proactive inspections help prevent costly downtime and enhance the longevity of the equipment.

Other checks, while important, may not need to be conducted with the same frequency. For example, cleaning the engine air filter and checking spark plugs are typically performed less frequently or as part of a more comprehensive maintenance routine. Lubricating wheel bearings is also critical but can usually be done during scheduled maintenance rather than weekly checks.
