the demolition HF 120 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. This causes an erosion
LOW TEMPERATURES At HF 120 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 in temperature of the machinery.
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 120 HF friction between metals.
