What to do if my Epiroc Power Tool hydraulic breaker does not start?

  Edward ThomasJul 25, 2025
  If the Epiroc Power Tool hydraulic breaker doesn't start, several factors could be at play. First, ensure that the pressure and tank hoses are correctly connected. Secondly, verify that the shut-off valves in the pressure and/or tank hoses are open. Also, check for any defective couplings that might be blocking the hoses and replace them if necessary. Furthermore, inspect the carrier engine speed, pump delivery, and pressure relief valve, ensuring the operating pressure is adequate. Adjust settings or replace defective parts as needed. Finally, high return pressure could be the culprit, so check and lower it accordingly.

Why is the impact force too low on my Epiroc SB?
- L
  Latasha White DVMAug 1, 2025
  If your Epiroc Power Tool's impact force is too low, it could be due to low gas pressure or hydraulic oil pressure. Check the gas pressure and fill the high-pressure accumulator, replacing the accumulator if necessary. Also, verify the hydraulic oil pressure and adjust as needed. If problems persist, consider fitting new pressure relief cartridges on both the carrier and breaker. Ensure proper installation, check the restrictor, and assess the carrier's pressure.

How to fix an Epiroc SB Power Tool that operates too slow?
- C
  Christopher BarkerAug 6, 2025
  If your Epiroc Power Tool operates too slowly, it could be due to insufficient hydraulic oil delivery volume. Check the engine speed and/or mode stage of the carrier, and adjust the operating pressure. Also, check the carrier's pressure and the size of the restrictor. Make sure the valves in the pressure and/or tank hoses are fully open. Lastly, inspect the oil filter and oil cooler for high flow resistance; clean or replace them as needed.

What to do if the working tool jams in the lower breaker part of my Epiroc SB?
- M
  Mark HuntAug 12, 2025
  If the working tool jams in the lower part of your Epiroc Power Tool, ensure the carrier boom's direction is correct, so the pressing force acts axially on the hydraulic breaker. Inspect the working tool's shaft and remove any burrs. Use the correct type and amount of recommended chisel paste. Also, check the working tool and wear bush for wear and replace if necessary. Furthermore, ensure the tank hose's inside diameter is adequate. High return pressure or hydraulic oil temperature may also cause the problem, so check and adjust them accordingly. Finally, verify the hydraulic oil pressure and adjust as needed.
