DO NOT EXECUTE IDLE STROKES Most frequently, during the 50 DRH 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
CONSTANT LUBIRICATION Even if the hammer DRH 50 is provided with a lubrication system, it is necessary to lubricate the tip of the tool to avoid the friction between metals.
between cracks. LOW TEMPERATURES. At low temperatures it is recommended that the tools be heated before use and if it is possible use at low speed for a 50 DRH progressive increase in temperature of the machinery. CORROSION. Rust or corrosion on the tool occurs when the tool is stored outdoors and it is not well lubricated.
