idle strokes. 280 DRH This 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
LOW TEMPERATURES At low temperatures it is recommended that the DRH 280 tools be heated before use and if it is possible use at low speed for a progressive increase in temperature of the machinery.
CONSTANT 280 DRH LUBIRICATION Even if the hammer is provided with a lubrication system, it is necessary to lubricate the tip of the tool to avoid the friction between metals.
