the subsequent rupture of the tip. The breaking in these cases usually appears at the top of the hammer pin as a result of the idle strokes when the tip of the tool is separated from the rest of the hammer. CONSTANT LUBIRICATION. Even if the 450 KM hammer is provided with a lubrication system, it

called idle strokes. This happens when the piston does not stroke the 450 KM hammer tool, and the impact force and energy is absorbed by bolts and the tool retaining screws and not by the tool itself. This causes an erosion and the subsequent rupture of the tip. The breaking in
