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 - / 550 551 HM 560 CS C560V / 555 740 / ALLIED HM - by bolts and the tool retaining screws and not by the tool itself. This causes an erosion and the subsequent rupture of
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 between metals.
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 HM 560 / 740 HM - 551 CS ALLIED 555 / C560V - 550 / progressive increase in temperature of the machinery.
