1. Move the construction machinery to a flat and open place and must pay attention to the presence of moisture, sludge and dust, etc., which are easily contaminated with hydraulic oil. Turn off the engine and note that when the hydraulic cylinder is pressurized, the pressure should be released first.
2. The shut-off valve installed at the end of the machine body is rotated by 90° to prevent the hydraulic oil from flowing out.
3. Remove the hose connector on the construction machine and recover the hydraulic oil flowing out and return it to the hydraulic tank.
4. Pay attention to avoid dust and sludge entering the hydraulic pipeline. Please close the hose and pipeline with hose plug and integrated cover to keep the oil system clean. The high and low pressure hoses are fixed to protect them from dirt.
5. When the hammer is to be removed, the two pins connecting the breaker and the boom can be extracted first. When working outdoors, place the breaker on a wooden block to isolate it from the ground and cover it outside.
6. When the breaker is not used for a long time (more than three weeks)
1) Please clean the outside first.
2) Remove the drill rod and apply it to the rust preventive oil, then store it, and then release the nitrogen gas before pushing the piston into the hydraulic cylinder.
3) Put the parts of the breaker into the lubricating oil and then put the rod back. After that, you can keep it on the bench.
7. When the hammer is to be reinstalled for work, it is necessary to reverse the above-mentioned unloading procedure. Since the construction machine is very likely to contaminate the hose and the pipeline after performing other operations, it should be replaced first. Clean the hydraulic lines and connectors.
