If you are experiencing a hydraulic problem with your Valmet 705, there are several steps you can take to fix it:

Identify the issue: Carefully examine the hydraulic system to determine the specific problem you are facing. Look for leaks, unusual noises, or any other signs of malfunction.
Inspect hydraulic fluid levels: Check the hydraulic fluid levels in the reservoir. If the levels are low, refill the reservoir with the appropriate hydraulic fluid according to the manufacturer's recommendations.
Check hydraulic filters: Inspect and clean or replace the hydraulic filters. Clogged filters can restrict fluid flow and cause hydraulic problems.
Examine hydraulic hoses and connections: Inspect all hydraulic hoses and connections for any signs of damage, leaks, or loose connections. Repair or replace damaged components as necessary.
Bleed air from the system: If you suspect air has entered the hydraulic system, bleed it by loosening the air bleeder valve and allowing any trapped air to escape. Once done, tighten the valve securely.
Inspect hydraulic pump: Check the hydraulic pump for any signs of wear or damage. If necessary, rebuild or replace the pump following the manufacturer's instructions.
Consult a professional: If the above steps do not resolve the issue, it is advisable to seek assistance from a qualified hydraulic technician or contact the Valmet customer support for further guidance.

Remember to always consult the Valmet 705 hydraulic system manual and follow all safety precautions when working on hydraulic systems.
