works, the strokes in soft or light materials are called idle strokes. This happens when the piston does not stroke the hammer tool, and the HB Marathon - HM 4000 7000 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
the tool itself. This causes an erosion and the subsequent rupture of the tip. The breaking in these cases usually appears at the top of the hammer pin as a HM Marathon 4000 7000 - HB result of the idle strokes when the tip of the tool is separated from the
CONSTANT LUBIRICATION Even if the hammer is provided with a lubrication system, it 4000 HB - HM 7000 Marathon is necessary to lubricate the tip of the tool to avoid the friction between metals.
