Why won't my Epiroc EC 70T hydraulic breaker start?

  If your Epiroc Construction Equipment's hydraulic breaker doesn't start, several issues could be the cause. First, ensure the pressure and tank hoses are correctly connected and not mixed up. Next, check if any shut-off valves in the pressure or tank hoses are closed and open them if necessary. Also, inspect the couplings for defects that might be blocking the hoses; replace any defective coupling valves. Furthermore, verify that 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, high return pressure can also prevent starting, so check and lower it if necessary.

Why is my Epiroc EC 70T hydraulic breaker operating too slow?

  Molly PrattAug 15, 2025
  If your Epiroc Construction Equipment hydraulic breaker is operating too slowly, it could be due to several reasons. One potential cause is an insufficient hydraulic oil delivery volume, so check the engine speed and mode stage of the carrier, as well as the operation pressure, and adjust as necessary. Also, inspect the pressure and tank hoses for partly closed valves and open them fully. High flow resistance on the oil filter or oil cooler can also slow operation; therefore, check, clean, or replace these components. Lastly, ensure the working tool isn't jammed in the lower breaker part by correcting the carrier boom's direction and deburring the tool's shaft if required; use the recommended chisel paste and inspect the working tool and wear bush for wear, replacing them if needed.

What to do if my Epiroc Construction Equipment operating temperature is too high?

  If your Epiroc Construction Equipment is showing a high operating temperature, there are a couple of things to check. First, make sure the oil level in the tank isn't too low; if it is, top it up. Also, consider whether you're operating in high outside temperatures without an oil cooler; if so, check the oil temperature and install an oil cooler if necessary.

How to increase the impact force on my Epiroc EC 70T Construction Equipment?

  If the impact force of your Epiroc Construction Equipment is too low, it could be due to low gas pressure or whipping and pulsing hoses. Check the gas pressure and fill the accumulator to resolve this issue.
