  • 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.

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.
