Additional Notes

  • Ensure  the carrier weight is strictly within the 36-55 t range, and the hydraulic system complies with rated specs: oil flow 250.0-350.0 L/min, operating pressure 150-160 bar. Mismatched data will cause severe impact imbalance, violent vibration, and even permanent damage to the breaker and carrier connection structure.
  • Use a professional torque wrench to fasten the 166.00 mm heavy-duty tool to the breaker with specified torque; check the tightness of fixing parts and the tool’s surface for wear, bending or cracking before each operation. Replace the tool immediately if any defect is found to avoid breakage during high-load work.
  • Forbid no-load dry firing under all working conditions and keep the tool fully attached to the working surface when striking. Control the impact rate within the rated range (400-560 bpm for long stroke, 520-700 bpm for short stroke); avoid continuous breaking on ultra-hard rock and stop the machine for cooling and inspection if abnormal noise or vibration occurs.
  • After operation, thoroughly clean the breaker body and tool to remove muck and dust, and seal hydraulic high-pressure interfaces with dedicated protective caps to prevent impurity entry. Regularly check the integrity of hydraulic hoses and joints, replace damaged seals/hoses in time, and use Sandvik-specified high-grade hydraulic oil to maintain stable system pressure and oil cleanliness.
