Tight Tolerances In Pistons and Cylinders: Eliminate leaks and jamming and guarantee full interchangeability of replacement parts.

Patented Hydraulic Dampening System: Extends the life of the breaker by preventing blank fire damage from the very first blow.

Energy Recovery System: Increases strike power by using energy generated by piston rebound.

Patented Main Valve Design: Reduces hydraulic pressure peaks that can reduce pump life, crack boom welds and cause system overheating.

Suspension System: Extends boom life by absorbing harmful vibration and stress waves.

Upper/Lower Suspension: Isolates power unit from the housing for maximum efficiency.

Tools: Choose from moil (general purpose), blunt (concrete and block breaking), chisel (concrete) and pyramidal/nail (concrete/hard materials).

Other Features: Includes bracket cap, hoses, automatic greaser, tool box with tools and check device.
