or / - 390 P12 290 - MDH PMV SH 29 / SB PMV 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 an erosion and the subsequent rupture of the tip. The
later it will break. The same thing occurs when the tool leans incorrectly or PMV P12 SB PMV / - / - 29 SH MDH 390 290 when it is introduced continuously between cracks. LOW TEMPERATURES. At low 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.
NOT BEND Using the power of the arm P12 / PMV SB 290 29 SH 390 / - PMV - MDH of the hammer to break, or using the tool of the hammer as a lever sooner or later it will break. The same thing occurs when the tool leans incorrectly or when it is introduced continuously between cracks.
