LOW TEMPERATURES At low temperatures it is recommended that the tools 700 / HB / 650 / 8 / MES / HP 601 621 / 621 601 UP / 650 be heated before use and if it is possible use at low speed for a progressive increase in temperature of the machinery.
and the impact force and energy is absorbed by bolts and 621 MES 650 650 621 8 / / / HP / / / UP HB / 601 700 601 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 system, it is necessary to lubricate the tip of the tool to avoid the 650 / 8 UP 621 700 601 / / MES / HB / 621 / HP / 650 601 friction between metals.
