the demolition works, the strokes in soft 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 by bolts and the tool retaining screws and not by the tool itself. PB 420 / 530 This causes an erosion and the subsequent
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 not in 530 PB / 420 use.
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 PB 420 / 530 friction between metals.
