LOW TEMPERATURES At low 711 BH - 70 MBB 50 S / VHR - 60 60 - 61 HU / 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 machinery.
CORROSION Rust or corrosion on the tool occurs when the tool is stored outdoors and it is not 60 61 711 MBB - / 50 BH / HU S VHR - 60 70 - well lubricated. This can be avoided by simple and easy lubrication and maintenance of hammer’s tool away from moisture when not in use.
or light materials are called - HU MBB 60 61 70 / - - 50 60 S VHR BH / 711 idle strokes. 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
