Why won't my Epiroc Construction Equipment hydraulic breaker start?
- A
  amooreAug 17, 2025
  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 Construction Equipment hydraulic breaker operating too slow?
- P
  Pamela SchmidtAug 20, 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?
- B
  bryan44Aug 23, 2025
  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 Construction Equipment?
- L
  Luke MuellerAug 26, 2025
  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.

Why is my Epiroc EC 40T hydraulic breaker operating too slowly?
- L
  Lisa LinSep 2, 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.

What to do if oil leaks from ports »P« und »T« in Epiroc EC 40T?
- G
  Gerald StanleySep 8, 2025
  If oil is leaking from ports »P« and »T« on your Epiroc Industrial Equipment, check the cap nuts and tighten them. Also, if the hose connection CL to port »P« for ContiLube® II or the plug is loose and ContiLube® II has not been installed, check the cap nuts and plugs and tighten them.

Why is the impact rate too high and impact force too low in Epiroc EC 40T Industrial Equipment?
- M
  Megan CookSep 12, 2025
  If the impact rate is too high and the impact force is too low in your Epiroc Industrial Equipment, check the gas pressure and fill the piston accumulator, as there may be no gas in the piston accumulator.

What to do if oil escapes between the cylinder cover and the cylinder of Epiroc EC 40T?
- C
  Catherine MillerSep 13, 2025
  If oil is escaping between the cylinder cover and the cylinder of your Epiroc Industrial Equipment, it could be due to loose tensioning bolts. Check the tensioning bolts and tighten them. Alternatively, the seals might be damaged, in which case you should replace them.
