the strokes in soft or light materials are called idle strokes. P P 30 12 - / PS P P12 / MHD / PS PMV P 300 400 PS 40 - 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.
CONSTANT 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 PMV P PS P12 / 30 400 P PS P 300 P / - 40 / 12 MHD PS - between metals.
CORROSION Rust or corrosion on the tool occurs when 12 P P12 PS / PMV 400 40 300 / - P - PS P / P MHD PS 30 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 when not in use.
