• Fault 2: Hydraulic Jitter & Unstable System Pressure
  Cause: Valve core abrasion, internal spring performance degradation.
  Solution: Fit Relief Valve With Pin, thoroughly clean the whole hydraulic oil circuit.
• Fault 3: Hydraulic System Overheat & Abnormal Working Noise
  Cause: Internal component wear, oil passages blocked by hydraulic contamination.
  Solution: Replace complete relief valve with pin assembly, check hydraulic oil cleanliness.
• Fault 4: Oil Leakage At Valve Mounting Position
  Cause: Seal ring aging, mating surface scratch damage.
  Solution: Replace full relief valve assembly or matching seal repair kit.
