or 280 DRH 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
CONSTANT LUBIRICATION Even if the hammer is provided with a lubrication system, it is necessary to lubricate the tip of the tool to avoid DRH 280 the friction between metals.
FOR USE. DO NOT EXECUTE IDLE STROKES. Most 280 DRH frequently, during the demolition 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
