Due to its simple, effective design this is the most productive hydraulic hammer on the market. And not just productive, but also very affordable to purchase and maintain. The amazing part is that it also has 2 - 4 times the warranty of most hammers with parts covered that other manufactures wouldn't dare. We offer a 2 Year Warranty with the only parts not covered are the chisel, bushings, and retainer pins. We also have very good prices on chisels to fit your existing hammers. Please give me a call and I will be glad to talk to you about these prices and answer any questions.                               Thank you, Jack Kelly
