Why is my Epiroc Industrial Equipment hydraulic breaker operating too slowly?

M
Michelle LaneJul 29, 2025
If your Epiroc Industrial Equipment's hydraulic breaker is operating too slowly, start by checking the engine speed and mode of the carrier, and adjust the operating pressure. Ensure the connecting fittings in the pressure and tank lines are tightened. Verify the shut-off valve in the pressure and tank line is fully open. Inspect the oil filter and oil cooler for high flow resistance, and clean or replace them. Also, check the gas pressure in the piston accumulator and release gas if needed. Finally, make sure the working tool isn't jammed; correct the carrier boom's direction, deburr the working tool's shaft if necessary, and inspect the working tool and wear bush for wear, replacing them if required.
