Walk-Around Inspection

When you approach your JLG 450AJ, it’s important to begin with a thorough walk-around inspection to ensure safe operation.

  • Check for visible damage to machine components like the boom, tires, hoses, and wiring.
  • Ensure there are no fluid leaks, loose fittings, or debris in areas like the hydraulic system, fuel tank, and engine.
  • Inspect the operator’s platform, safety decals, and switches to confirm all are clean, intact, and functional.

Daily Inspection

Perform a detailed daily inspection to keep your 450AJ in peak working condition. Follow these key steps:

  • Check engine oil and coolant levels, replenishing them if necessary.
  • Inspect the hydraulic oil level and top it off if required, using the sight gauge to ensure proper levels.
  • Inspect fuel levels and make sure the fuel tank is securely sealed.
  • Grease all necessary lubrication points, particularly around moving joints and pins.

300 Hour Maintenance

Every 300 hours, it's essential to perform several key maintenance tasks to keep the hydraulic system functioning efficiently:

  • Replace the hydraulic return filter to maintain proper fluid cleanliness.
  • Replace the hydraulic charge filter to ensure system efficiency.
  • Inspect the hydraulic hoses and connections for any signs of wear or leaks.

600 Hour Maintenance

At every 600-hour interval, you should perform the following maintenance to ensure longevity:

  • Replace the engine oil and filter to ensure smooth operation.
  • Inspect the fuel system and replace the fuel filter as necessary.
  • Check and tighten all critical boom and chassis components.
