happens when the piston 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 rupture of the tip. The breaking in these cases HB 80 usually appears at the top
LOW TEMPERATURES At low temperatures it is recommended that the tools be heated before use and if 80 HB 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 is necessary to lubricate the tip of the tool 80 HB to avoid the friction between metals.
