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 550 K 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
LOW TEMPERATURES At low temperatures it is recommended that the tools 550 K be heated before use and if it is possible use at low speed for a progressive increase in temperature of the machinery.
CONSTANT LUBIRICATION Even if the hammer is 550 K provided with a lubrication system, it is necessary to lubricate the tip of the tool to avoid the friction between metals.
