The tool bit must be lubricated frequently to prevent accelerated wear of the tool bushings. Most manufacturers recommend applying tool grease (aka chisel paste) every 1-3 hours of operation. The type of grease is also important as it must stand up to the heavy-duty requirements of breaking rocks. Fel-Tech sells specially-formulated tool grease in standard grease-gun tubes and in 35 lb pails for bulk application. Our grease is recommended for use in all manufacturers of hammers, and can prevent costly repairs down the road.
