Additional Notes

  • Strictly match pressure 260270 bar & oil flow 250340 l/min. Overpressure/excess flow is prohibited to avoid overload damage to seals & main valve.
  • Suitable for 4050 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.
