Common Hydraulic System Issues
The TB025's hydraulic system, while efficient, can encounter issues over time:

• Hydraulic Power Loss: Loss of hydraulic power, especially after the system heats up, can be attributed to a faulty relief valve or internal bypass in the pump. Regular inspection and maintenance of the hydraulic pump and relief valve are essential.
  
• Hydraulic Slowness and Uneven Track Speed: Clogged hydraulic filters, air in the system, or worn hydraulic pumps can cause sluggish movement. It's advisable to inspect and replace hydraulic filters, bleed the hydraulic lines to remove trapped air, and check hydraulic fluid levels and quality.
  

Maintenance Tips
To ensure the longevity and optimal performance of the TB025:

• Regular Inspections: Conduct routine checks on hydraulic filters, hoses, and seals to prevent leaks and ensure system efficiency.
  
• Proper Fluid Levels: Maintain appropriate hydraulic fluid levels and quality to prevent contamination and ensure smooth operation.
  
• System Flushing: Periodically flush the hydraulic system to remove contaminants and prevent internal damage.
  
• Component Checks: Regularly inspect the hydraulic pump, relief valve, and other critical components for wear and tear.
