The hydraulic system is the heart of an excavator. A disciplined maintenance routine dramatically extends component life and reduces unexpected downtime.
Maintenance checklist:
- Drain and replace hydraulic oil on schedule — recommended every 2000 operating hours
- Inspect and replace the hydraulic oil return filter every 500 hours
- Keep hydraulic oil clean and protect the reservoir from contamination
- Periodically inspect hoses, fittings and seals for seepage or leaks
Consistent hydraulic-system maintenance can reduce the overall failure rate by over 30%.
