DO NOT EXECUTE IDLE STROKES
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 W 440 breaking in these cases usually appears at the
CONSTANT LUBIRICATION
CONSTANT LUBIRICATION Even if the hammer is provided with a lubrication system, it is necessary to 440 W lubricate the tip of the tool to avoid the friction between metals.
LOW TEMPERATURES
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 W 440 in temperature of the machinery.
