1. Identify the issue: Determine the specific problem with the hydraulic system. It could be a lack of pressure, unresponsive controls, leaks, or any other symptom affecting the hydraulics.
2. Inspect for visible damage or leaks: Perform a visual inspection of the hydraulic system components, including hoses, fittings, cylinders, and valves. Look for any signs of damage, loose connections, or fluid leaks. Address any visible issues by repairing or replacing damaged components.
3. Check hydraulic fluid level and condition: Ensure that the hydraulic fluid reservoir is filled to the recommended level. Also, check the condition of the fluid. Contaminated or degraded fluid can cause hydraulic problems. If needed, drain and replace the hydraulic fluid.
4. Inspect hydraulic filters: Examine the hydraulic filters for clogs or excessive dirt. Clogged filters can restrict fluid flow and cause issues. Clean or replace the filters as necessary.
5. Test hydraulic pump: Check the output pressure of the hydraulic pump using a pressure gauge. If the pump is not generating sufficient pressure, it may need to be repaired or replaced. Consult the tractor's manual or contact a qualified technician for guidance.
6. Inspect control valves: Examine the control valves for proper operation. Malfunctioning valves can cause erratic or unresponsive hydraulic functions. Clean, repair, or replace valves as needed.
7. Address fluid leaks: If there are visible hydraulic fluid leaks, identify the source and repair the damaged components. This may involve replacing seals, O-rings, or damaged hoses. Make sure all connections are tight and secure.
8. Bleed the hydraulic system: If air has entered the hydraulic system, it can cause spongy or erratic operation. Bleed the system by following the manufacturer's instructions to remove air and ensure proper hydraulic function.
9. Test the system: Once you have addressed the specific issues, test the hydraulic system to ensure that the problem has been resolved. Check all hydraulic functions, including lift arms, attachments, and any other components that utilize the hydraulic system.

If you are not familiar with hydraulic systems or if the problem persists after attempting these steps, it is advisable to contact a certified Zetor technician or an authorized service center for further assistance. They will have the necessary expertise and tools to diagnose and repair complex hydraulic issues specific to the Zetor PROXIMA POWER tractor.
