- Inspect and clean or replace hydraulic filters every 500 hours to maintain proper hydraulic system performance. Check hydraulic oil levels and for any leaks in hoses and fittings.
- Regularly inspect the fuel system for leaks and ensure the fuel filter is clean. Drain water from the fuel tank to prevent fuel contamination and injector issues.
