How to choose the hydraulic breaker for your machine
A mismatched breaker performs poorly and breaks fast; a well-chosen one shatters more with less effort. Selection and chisel technique decide the tool's lifespan.

reposition the chisel
Match by carrier weight and flow
Each breaker matches a range of operating weight and hydraulic flow. A big breaker on a small machine punishes it; a small one on a big machine underperforms. Send us your machine model and we'll confirm the fit.
Chisel technique: preload and perpendicular
Set the chisel at 90° and apply down-pressure (preload) before percussing. Start at a free edge, not the center, and find the fracture plane in bites.
Never dry-fire
If the chisel doesn't break in 15–30 seconds, move it: persisting overheats and glazes the steel. And never percuss with no material (dry-firing): it's the fastest way to wreck a breaker. Grease the bushing often, with the tool vertical.
Takeaway
Match the breaker to your machine's weight and flow, keep the chisel perpendicular with preload, reposition every 15–30 s and NEVER dry-fire. Tell us your carrier and we'll confirm the exact breaker.
Frequently asked
Do you have breakers for skid steers and backhoes?
Yes: a line for skid steers, backhoes and excavators. We pick the model by your machine's weight and flow.
Are they suitable for urban areas, noise-wise?
SIMAQ DB models are designed for lower noise and vibration, ideal for urban zones and long shifts.
