the tool retaining screws and not by the tool itself. This causes an erosion and the subsequent rupture of the tip. The breaking in 115 H these cases usually appears at the top of the hammer pin as a result of the idle strokes when the tip of the tool
strokes in soft or light materials are called idle strokes. This happens when the piston does not stroke the hammer tool, and H 115 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
CONSTANT LUBIRICATION Even if the hammer is provided with a lubrication system, it is necessary to lubricate the 115 H tip of the tool to avoid the friction between metals.
