The hydraulic hammer of the excavator arm extension belongs to the impact hydraulic vibration device, also known as the crusher. In engineering, it is mainly used for crushing, drilling and demolition of hard objects such as rock, reinforced concrete, asphalt cement pavement and old buildings.

　　Instructions for use of hydraulic breaking hammer for excavator boom extension:

　　(1)每次使用时检查的高低压油管是否松动;同时，随时检查部位有无漏油现象，

　　(1) check whether the high-pressure and low-pressure oil pipes of the breaking hammer are loose each time they are used; at the same time, be careful to check whether there is oil leakage in other parts at any time to prevent the failure caused by the vibration of the oil pipes.

钻杆应始终垂直于被破碎物体的表面。

　　(2) the drill pipe shall always be perpendicular to the surface of the object to be broken during the operation of the crushing hammer. The drill pipe shall be broken to the object under pressure, and the hammering work shall be stopped immediately after breaking to prevent the air blow.

　　无目标的冲击会造成锤头前体的损伤和主螺栓的松动，

　　The continuous impact without target will cause the damage of the hammer head precursor and the loosening of the main bolt, which will cause serious damage to the main engine itself.

主螺栓和钻头杆可能断裂;让铁锤快速下落或猛烈撞击的岩石，过度撞击而损坏铁锤或主机。

　　(3) when breaking, do not use the rock bit rod, or the main bolt and the bit rod may break; do not let the hammer fall quickly or hit hard rock violently, so as to avoid damaging the hammer or the main engine due to excessive impact.

身体的部位的不适合浸在水中或泥浆,具有类似功能的部分将会导致的由于积累的泥渍。

　　(4) do not perform the operation of crushing in water or mud. Except for the drill pipe, the crushing hammer in other parts of the body is not suitable for immersion in water or mud. Otherwise, the piston, other parts with similar functions, will lead to premature crushing hammer due to accumulated mud stains.

烧坏钻杆或过热。

　　(5) when the particularly hard object is damaged, it shall be knocked continuously for no more than 1min from the edge to avoid burning the drill pipe or overheating the hydraulic oil.

　　(6)使用的防护板作为一种工具来推动重量,

　　(6) do not use the protective plate of the breaking hammer as a tool to push the weight, because it is mainly the small machine of the excavator loader, which has light weight. If you let it handle the weight, the light will lead to the breaking hammer, the heavy will lead to the fracture of the crane arm, or even the main engine overturns the accident.

冲击振动会传到液压缸体，

　　(7) do not operate when the hydraulic cylinder is fully extended or fully contracted, otherwise the impact vibration will be transmitted to the hydraulic cylinder and then to the main engine.
