  Nathan HartAug 10, 2025
  If your Epiroc Construction Equipment hydraulic breaker doesn't start, several factors could be the cause. Here's what you should check: * Ensure the pressure and tank lines are correctly connected. * Verify that the shut-off valve in the pressure and/or tank line is open. * Confirm the gas pressure in the piston accumulator is at the correct level. * Check and replenish the oil level in the tank if it's too low. * Inspect couplings for defects that may be blocking the pressure and tank lines. * Examine the electrical system for any faults. * See if the magnet on the switch-on valve is damaged and replace if necessary. * Make sure the operating pressure is not too low; adjust settings and replace any defective parts.

  If your Epiroc Construction Equipment hydraulic breaker is operating too slowly, consider these potential causes and solutions: * Check if the hydraulic oil delivery volume is sufficient and adjust the engine speed or mode stage of the carrier and the operation pressure. * Ensure that the connecting fitting in the pressure and tank line is tightened. * Confirm that the shut-off valve in the pressure and/or tank line is fully open. * Inspect the oil filter and oil cooler for high flow resistance; clean or renew them as needed. * Verify the gas pressure in the piston accumulator and release some gas if it's too high. * Make sure the working tool isn't jammed; correct the carrier boom's direction, check the shaft of the working tool, and inspect the working tool and wear bush for...

  Benjamin ThomasNov 19, 2025
  If your Epiroc Construction Equipment hydraulic breaker won't start, consider these potential causes: * The pressure and tank lines might be swapped. Ensure they are correctly connected. * The shut-off valve in the pressure or tank line might be closed. Check and open it. * The gas pressure in the piston accumulator might be too high. Check and adjust it. * The oil level in the tank might be too low. Check and top up the oil. * There might be defective couplings blocking the pressure and tank lines. Inspect and replace them. * There could be faults in the electrical system. Check and clear any faults. * The magnet on the switch-on valve might be damaged. Replace the magnet. * The operating pressure might be too low. Inspect the carrier engine speed, pump delivery, and pres...

  If your Epiroc Construction Equipment hydraulic breaker operates too slowly, it could be due to several reasons. First, check if the hydraulic oil delivery volume is sufficient, adjusting the engine speed and operation pressure as needed. Also, ensure the connecting fitting in the pressure and tank line is tight. Make sure the shut-off valve in the pressure and/or tank line is fully open. Inspect the oil filter and oil cooler for high flow resistance, cleaning or replacing them if necessary. Check the gas pressure in the piston accumulator and release gas if it's too high. Confirm that the working tool isn't jammed, and correct the carrier boom's direction. Check the inside diameter of the tank line and change if required. Finally, verify that the return pressure isn't too high, and lower ...

  Amanda GomezDec 1, 2025
  If your Epiroc Industrial Equipment hydraulic breaker fails to start, several issues could be the cause. First, ensure that the pressure and tank lines are correctly connected and not swapped. Next, verify that the shut-off valve in the pressure or tank line is open. Check the oil level in the tank and top up if it is low. Also, inspect the couplings for defects that may be blocking the lines and replace any defective coupling halves. Furthermore, examine the electrical system for faults and correct them. If these steps don't resolve the issue, the gas pressure in the piston accumulator might be too high, requiring adjustment. Finally, check the operating pressure, carrier engine speed, pump delivery, and pressure relief valve, adjusting settings and replacing defective parts as needed. If...
