When the hydraulic breaker is installed and connected to the hydraulic excavator or other construction machinery, the working pressure and flow rate of the main machine hydraulic system must meet the technical parameter requirements of the hydraulic breaker, and the "P" port of the hydraulic breaker is connected to the main engine high-pressure oil circuit. The "A" port is connected with the main engine oil return line.

1) The best hydraulic oil temperature for hydraulic breaker is 50-60 degrees, and the maximum hydraulic breaker should not exceed 80 degrees. Otherwise, the load of the hydraulic breaker should be reduced.

2) The working medium used by the hydraulic breaker can usually be the same as the oil used in the main hydraulic system. It is recommended to use YB-N46 or YB-N68 anti-wear hydraulic oil in general areas, and YC-N46 or YC-N68 low temperature hydraulic oil in cold areas. The filtration accuracy of hydraulic oil is not less than 50 micro m.

3) New and repaired hydraulic breakers must be refilled with nitrogen when they are activated, and the pressure is 2.5, ±0.5MPa.

4) Calcium-based grease or compound calcium-based grease must be used between the drill chisel handle and the cylinder guide sleeve.

5) When the hydraulic breaker is working, the chisel must be pressed on the rock first, and the breaker must be operated after maintaining a certain pressure. It is not allowed to start in the suspended state.

6) It is not allowed to use the hydraulic breaker as a crowbar to avoid breaking the chisel.

7) The hydraulic breaker and the fiber rod should be perpendicular to the working surface when in use, and the principle of not generating radial force
