5 minHow to use the hydraulic breaker
The hydraulic breaker shatters concrete and rock mounted on your carrier. Chisel technique —and never dry-firing— is what protects the tool.

- 01
Match the breaker to your carrier
Skid steer, backhoe or excavator: the breaker must match your machine's weight and flow. Confirm the fit first.
- 02
Set the chisel perpendicular
Rest the chisel at 90° to the surface and apply down-pressure (preload) before percussing.
- 03
Start at the edge, not the center
Break from a free edge inward, in bites. Find the fracture plane; don't punch one deep hole.
- 04
Reposition every 15–30 seconds
If it hasn't broken by then, move the chisel. Pounding one spot overheats and glazes the steel.
- 05
Grease the chisel often
Grease the chisel bushing every couple of hours (or per the manual), with the breaker vertical and resting.
Do this
- Always keep down-pressure (preload) while percussing.
- Reposition the chisel the moment material stops yielding.
- Grease the bushing often, with the tool vertical.
Avoid this
- NEVER dry-fire (no material): it wrecks the breaker.
- Don't use the chisel as a pry bar to move rubble.
- Don't percuss more than ~30 s on the same spot.
Safety
- Closed cab or face shield, glasses, gloves and hearing protection.
- Exclusion zone: flying chips travel far.
- Never anyone under the boom or in the line of fire.
