Hydraulic breakers are built for high-impact, heavy-duty applications—but after extended use, you may notice reduced power or slower striking frequency. This can affect job efficiency and overall productivity on site. The good news is that most performance issues can be resolved with proper inspection and adjustment.
Before making any adjustments, start with these essential checks:
Key Checks Before Adjustment
-
Working Pressure
Ensure the hydraulic system pressure meets the breaker’s recommended operating range. -
Back Head Gas Pressure
Verify the nitrogen gas pressure in the back head is set correctly. -
Accumulator Gas Pressure
Check the accumulator to ensure stable energy storage and impact performance. -
Chisel Installation
Confirm the chisel is installed in the correct position and fully secured.
Fine-Tuning the Breaker Performance
If the breaker still feels underpowered after completing the checks above, you can adjust the Adjuster Valve located on the cylinder (above the outlet port).
Adjustment Method:
-
Loosen the adjuster valve by 0.5 turn at a time, testing performance after each adjustment
-
In most cases, a total adjustment of 2 to 2.5 turns is sufficient to restore optimal performance.
Important Reminder
Proper adjustment keeps your hydraulic breaker powerful, stable, and job-ready.
