• Fault 2: Swing Jitter & Unstable Swing Pressure
  Cause: Valve core abrasion, internal spring performance degradation.
  Solution: Fit SK07 Swing Relief Valve, thoroughly clean the whole hydraulic oil circuit.
• Fault 3: Hydraulic System Overheat & Abnormal Swing Noise
  Cause: Internal component wear, oil passages blocked by hydraulic contamination.
  Solution: Replace complete swing relief valve assembly, check hydraulic oil cleanliness.
• Fault 4: Oil Leakage At Swing Relief Valve Mounting Position
  Cause: Seal ring aging, mating surface scratch damage.
  Solution: Replace full swing relief valve assembly or matching seal repair kit.
