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 90 MH the tip. The breaking in these cases usually appears at the top of the hammer pin as a result of the idle strokes
STROKES Most frequently, during 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 MH 90 by bolts and the tool retaining screws and
CONSTANT LUBIRICATION Even if the hammer MH 90 is provided with a lubrication system, it is necessary to lubricate the tip of the tool to avoid the friction between metals.
