1
Working tool:
Selected special high quality steel and the most advanced heat treatment available anywhere ensure outstanding wear and shock resistance.
2
Valve:
State-of the art machining and design provide the highest standard of reliability available anywhere for this critical assembly.
3
Accumulator:
Creates additional impact power and releases stress on the hydraulic pump.
4
Oval chisel pin:
The strong oval shape allows turning over right, left, up and down, distributing wear evenly and extending service life.
5
Shank bushing:
Extended length provides a larger bearing surface and minimizes wear.
6
Piston:
Increased weight and long stroke design produce superior impact energy.
