This happens when the piston does not stroke the hammer tool, and the impact force and energy is absorbed by bolts and the tool retaining HM V 185 - B HM - HM 190 725 - 170 ALLIED screws and not by the tool itself. This causes an erosion and the subsequent rupture of the tip. The breaking in these cases usually appears at
LOW TEMPERATURES At low temperatures it is V 185 HM ALLIED 190 - HM 725 - B HM 170 - recommended that the tools 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 provided with a lubrication system, it HM V 725 190 ALLIED 185 - 170 - B HM - HM is necessary to lubricate the tip of the tool to avoid the friction between metals.
