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 breaking in these AT 70 cases usually appears at the top
when it is introduced continuously between cracks. LOW TEMPERATURES. At low temperatures it 70 AT 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. CORROSION. Rust or corrosion on the tool occurs
CORROSION Rust or corrosion on the tool occurs when the tool is stored outdoors and it is not well lubricated. This can be avoided by simple and easy lubrication and maintenance of hammer’s tool away from moisture when 70 AT not in use.
