the 620 BRH 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 cases usually appears at the top of the hammer pin
hammer as a lever sooner or later it will break. The same thing occurs when the tool 620 BRH leans incorrectly or when it is introduced continuously between cracks. LOW TEMPERATURES. At low temperatures it is recommended that the tools be heated before use and if it is possible
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 friction BRH 620 between metals.
