is absorbed by bolts and the tool retaining screws and not by the (with 90 collar) OL tool itself. This causes an erosion and the subsequent rupture of the tip. The breaking in these cases usually appears at the top of the hammer pin as a result of the idle strokes when
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 90 (with OL collar) in temperature of the machinery.
CORROSION Rust or corrosion on the tool occurs when the tool is stored outdoors and it is not 90 (with collar) OL well lubricated. This can be avoided by simple and easy lubrication and maintenance of hammer’s tool away from moisture when not in use.
