Overview
The SB10 hydraulic breaker represents the entry point of the SB series — a purpose-built mini breaker engineered for the growing market of compact excavators and skid steer loaders. Operating in the 1–4 ton excavator class, the SB10 delivers reliable percussion performance in applications where larger breakers simply cannot fit or would overload the carrier machine.
With an operating weight of 85–110 kg and a hydraulic oil flow requirement of just 20–35 L/min, the SB10 places minimal demand on the carrier's hydraulic system. This makes it compatible with a wide range of mini excavators from manufacturers including Kubota, Yanmar, Takeuchi, Bobcat, and Caterpillar in the 1–4 ton class.
The SB10's 45mm chisel diameter and 150–250 J impact energy are well-matched to light concrete, soft rock, frozen ground, and utility trenching applications. The high impact frequency of 900–1200 blows per minute compensates for the lower energy per blow, making the SB10 effective in materials that respond well to rapid percussion.

Operating Recommendations
Avoid blank firing — always maintain chisel contact with material
Do not operate at angles greater than 30° from vertical
Keep operating cycles under 15 seconds on hard rock to prevent overheating
Use the correct chisel type for the material being broken
Maintenance Guidelines
Grease chisel bushing every 2 hours of operation
Check nitrogen pressure weekly — target 5–7 bar when cold
Inspect hydraulic hose connections daily
Replace chisel when worn below minimum diameter marking
