LOW TEMPERATURES At low temperatures it is recommended that the 90 D tools be heated before use and if it is possible use at low speed for a progressive increase in temperature of the machinery.
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. D 90 The breaking in these cases usually appears at the top
