the impact force and energy is absorbed by bolts 100 100Q HM HM / 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 these cases usually appears at the top of the hammer pin as
CONSTANT LUBIRICATION Even if the hammer is provided with a lubrication HM 100 100Q HM / system, it is necessary to lubricate the tip of the tool to avoid the friction between metals.
LOW TEMPERATURES At low 100 / HM HM 100Q temperatures it is 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.
