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 HB 400 tip. The breaking in these cases usually appears at the top of
during the demolition works, the strokes in soft or light materials are HB 400 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
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 HB 400 not in use.
