2. The power system, hoist, hydraulic control valve, electrical equipment, etc. equipped with the pile driver should be controlled according to its operating procedures.

3, The coal in the electrical fault of the pile driver shall be solved by the electrician.

4. The test run, assembly, disassembly and hauling of the pile driver should strictly abide by the relevant regulations.

5. In case of severe weather such as thunder, rain, snow, fog and wind above level 6, the operation should be suspended. When the wind force exceeds level 7 or there is a strong typhoon warning, the pile driver should first stop with the wind direction. If necessary, first The frame is put down. The pile driver is protected by lightning protection. In case of lightning, the staff need to avoid pile driving.

6. Before operation, it should be run dry first, and it can only be operated after confirming that the sh10 of each part is in normal state.

② The fastening bolts of the vibratory hammer motor are loose, the guiding equipment is loose, there is impact sound in the vibrator, the bearing temperature is too high, and the connecting bolts between the vibratory hammer and piles or other equipment are loose.

③ Electrical equipment, hydraulic control valve failure.

15. If the amplitude of the vibratory hammer shock-absorbing beam is too large for a long time, it should be shut down to find out the reason.
