When crushing, the hammer head will gradually change its direction due to vibration, so the excavator bucket cylinder should be adjusted at any time to make the direction of the hammer head perpendicular to the surface of the broken object.
When the hammer head cannot penetrate the broken objects, the crushing position should be changed; continuous crushing in one place should not exceed one minute, otherwise not only the hammer head will be damaged, but also the oil temperature will rise abnormally; for hard objects, it should be broken gradually from the edge .
It is strictly forbidden to break while turning, twist the hammer head after insertion, use the hydraulic hammer horizontally or upwards, and use the hydraulic hammer as a chisel.
