absorbed 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 in these cases usually appears at the top of the hammer pin as HB / / / / 500 451 / HP / / 450 500 5 MES 462 521 521 / / 550 UP 550 a result of the idle strokes when the tip of the tool is separated
LOW TEMPERATURES At low 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 / / / 521 HB 500 / 450 5 UP 451 / 462 HP / 550 / MES 521 500 550 / / machinery.
DO NOT BEND Using the power of the arm of the hammer to break, or using the tool of the hammer as a lever sooner or later it will break. The same thing occurs when the 500 / 521 450 / / 5 / / / HB 550 MES UP HP 521 451 / / 462 / 550 500 tool leans incorrectly or when it is introduced continuously
