Why is my Epiroc HB 4700 Industrial Equipment hydraulic breaker operating too slowly?

  Julie TaylorAug 13, 2025
  If your Epiroc Industrial Equipment hydraulic breaker is operating too slowly, the issue might stem from several factors. Begin by checking the engine speed and/or mode stage of the carrier, as well as the operating pressure, and make any necessary adjustments. Ensure that the connecting fitting in the pressure and tank line is securely tightened. Verify that the shut-off valve in the pressure and/or tank line is fully open. Inspect the oil filter and oil cooler for excessive flow resistance, cleaning or replacing them as needed. Lastly, confirm that the gas pressure in the piston accumulator isn't too high; if it is, release some gas.

  To address a low impact force issue on your Epiroc Industrial Equipment, begin by checking the gas pressure. If the gas pressure is too low fill the piston accumulator. Also, check the pump of the hydraulic installation to ensure it delivers sufficient oil; if it doesn't, compare its characteristic with a measuring device to the original details and renew the pump if required.
