Additional Notes

  • Strictly match pressure 260–280 bar & oil flow 260–350 l/min. Overpressure/excess flow is prohibited to avoid overload damage to seals & main valve.
  • Suitable for 45–55 ton excavators. Installed by professionals. Fully bleed air from hydraulic lines to prevent cavitation damage.
  • Prolonged dry firing & side loading forbidden. Adjust frequency per rock hardness to reduce abnormal wear of chisel & piston.
  • Regularly check oil cleanliness, accumulator pressure & seals. For long-term storage: rustproof, relieve pressure & keep dry.
