5. High Flow Issues
Problem: Reduced Power in High Flow Operations
High flow hydraulics are crucial for attachments like mulchers and trenchers. Reduced power can hinder performance.
Cause:
- Blocked high flow filter.
- Insufficient hydraulic fluid pressure.
Solution:
- Clean or replace the high flow filter.
- Check hydraulic pressure levels and adjust as necessary.
- Consult the operator’s manual for troubleshooting specific high flow attachments.
Proactive Maintenance Tips
- Inspect regularly: Conduct visual inspections of key components weekly.
- Follow the manual: Adhere to the maintenance schedule outlined in the operator’s manual.
- Use genuine parts: Always replace parts with OEM-certified components to ensure compatibility and durability.
- Monitor performance: Stay alert to unusual sounds, smells, or performance drops.
