Additional Notes

  • Rated pressure must be strictly kept at 14–18 MPa; overpressure operation is forbidden. Flow must be within 160–215 L/min. Overpressure/over‑flow accelerates seal aging and cracking; insufficient flow causes dry friction and weak impact.
  • The seal kit uses PU+PTFE+FKM+NBR composite for high‑temperature, dusty, heavy‑duty conditions. Allow the machine to cool naturally after high‑temperature work to avoid seal deformation from thermal expansion and contraction.
  • Inspect seals every 700–1100 working hours. Replace the full kit immediately if oil leakage, dust seal wear, or buffer seal bulging occurs to prevent piston and chisel jamming from sand contamination.
  • Clean cylinder and seal mating surfaces before installation, apply special hydraulic seal grease, and ensure even assembly clearance. Do not hammer seals forcibly to avoid lip damage.
  • No blank striking is allowed. Dry firing causes hard impact between seals and piston, leading to seal damage and cylinder scoring. Ensure the chisel fully contacts the working surface before striking.
