incorrectly or when it is introduced continuously between cracks. LOW TEMPERATURES. At low 90 MH 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. CORROSION. Rust or corrosion on
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 MH 90 breaking in these cases usually appears at the top of the hammer pin as a result of the idle strokes when
CONSTANT LUBIRICATION Even if the hammer is provided with a lubrication MH 90 system, it is necessary to lubricate the tip of the tool to avoid the friction between metals.
