The hydraulic system is the heart of an excavator. A disciplined maintenance routine dramatically extends component life and reduces unexpected downtime.

Maintenance checklist:

1. Drain and replace hydraulic oil on schedule — recommended every 2000 operating hours
2. Inspect and replace the hydraulic oil return filter every 500 hours
3. Keep hydraulic oil clean and protect the reservoir from contamination
4. Periodically inspect hoses, fittings and seals for seepage or leaks

Consistent hydraulic-system maintenance can reduce the overall failure rate by over 30%.
