Why is my Epiroc HB 3100 hydraulic breaker operating too slowly?
- H
  Heather DouglasAug 12, 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.

  Pamela AdamsAug 17, 2025
  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.

What to do if Epiroc HB 3100 hydraulic breaker does not start?
- R
  Robert MccartyNov 6, 2025
  If your Epiroc Industrial Equipment hydraulic breaker doesn't start, several issues could be the cause. First, ensure the pressure and tank lines aren't swapped and are correctly connected. Next, check that the shut-off valve in the pressure and/or tank line is open. Also, verify that the gas pressure in the piston accumulator isn't too high, and adjust if necessary. Check that the oil level in the tank is adequate and top up if low. Inspect couplings for defects and replace any faulty ones. Examine the electrical system for faults and correct them. If the magnet on the switch-on valve is damaged, replace it. Ensure the operating pressure isn't too low by checking the carrier engine speed, pump delivery, and pressure relief valve, adjusting settings or replacing parts as needed. Finally, c...
