works, the strokes in soft or light materials are called 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 / 30 40 300 P PS PS / P12 400 MHD / PMV P P - 12 - PS P an erosion and the subsequent rupture
CORROSION Rust or corrosion on the tool occurs when the tool is stored outdoors and it is not well lubricated. This can be avoided by simple and easy lubrication and maintenance of hammer’s tool away from moisture 12 - / 40 - 300 PMV P PS PS P / 400 P / PS MHD P P12 30 when not in use.
CONSTANT LUBIRICATION Even if the hammer is provided PS - PS PMV P - P12 / 300 P / MHD PS 12 40 / P 30 400 P with a lubrication system, it is necessary to lubricate the tip of the tool to avoid the friction between metals.
