does not stroke the hammer tool, and the impact force and energy is absorbed by bolts and the tool retaining screws and not by the tool itself. This causes an erosion and the subsequent HB 980 rupture of the tip. The breaking in these cases usually appears at the top
CONSTANT LUBIRICATION Even if the hammer is provided with a lubrication system, it is necessary to lubricate the tip of the 980 HB tool to avoid the friction between metals.
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 980 HB machinery.
