Is the hydraulic hammer used correctly?

On August 24, 2021, is the hydraulic hammer used correctly?
The hydraulic hammer is mainly composed of the following parts: hammer head / pile frame / hammer head lifting cylinder and so on. The hammer head is installed in the vertical guide rail of the pile frame to ensure sufficient force.
When working, control the hydraulic valve to control the in and out of the oil circuit, pull the hammer head of the lift cylinder to a predetermined height, and then control the hydraulic valve to cut off the oil intake, and at the same time open the main oil circuit of the lift cylinder to make the hammer head fall freely. Complete piling work.
The use of hydraulic hammer is driven by hydraulic oil pressure. It can adjust the hydraulic pressure according to different soil quality, so as to achieve the appropriate impact force. Therefore, it is increasingly used in the industry and becomes the mainstream of piling hammers in the future.
The hydraulic hammer is powered by the hydraulic power system and is transported to the pile hammer through a high-pressure hydraulic hose to lift the hammer core. When the hydraulic cylinder core is raised to a certain height, the upper and lower pressures of the hydraulic cylinder piston are the same as the hydraulic directional valve. At this time, the piston falls freely under the action of gravity, and the hammer core produces a striking effect to complete the piling process. So is the method of using a hydraulic hammer correct? The following editor will give you a detailed introduction, I hope it will be helpful to you:
1) Carefully read the operating manual of the hydraulic hammer;
2) Before operation, check whether the bolts and connectors are loose and whether the hydraulic pipeline is leaking;
3) Do not peck holes in hard rocks with hydraulic pile hammers;
4) The breaker shall not be operated in the fully extended or fully retracted state of the piston rod of the hydraulic cylinder;
5) When the hydraulic hose vibrates violently, stop the operation of the breaker and check the pressure of the accumulator;
6) Except for the drill bit, do not immerse the breaker in water;
7) The breaker shall not be used as a lifting device.
