With the range of Mini-Excavators rapidly expanding, some 17 subdivisions of bucket capacity (from 0.5 to 5 tons) are now recognized. To match this increased range the new small F-series breakers are available in five models, each designed to match specific needs.
The new Furukawa maintenance-free breaker models, F1 to F5 offer a clear distinction from combined hydraulic / gas ones. The F6 and F9 breakers are of the combined hydraulic / gas design.
