Common Issue: Hydraulic System Pressure Loss in Hyundai R210-9
Symptoms: Slow movement and inability to lift heavy loads.
Solution: Inspect the Main Relief Valve (31N6-17400). Debris or spring fatigue inside the valve can cause pressure bypass. Cleaning or replacing the cartridge typically restores full power. Always check hydraulic oil cleanliness every 1000 hours to prevent valve seat wear.
