How to use the hydraulic hammer correctly?

Correct use of hydraulic hammer now take common specifications as an example to illustrate the correct use of hydraulic hammer.
1) Read the hydraulic hammer operation manual carefully to prevent damage to the hydraulic hammer and excavator and operate effectively.
2) Before operation, check whether the bolts and connectors are loose and whether the pipeline leaks.
3) Do not use a hydraulic hammer to peck holes in hard rock.
4) Do not operate the hammer when the piston rod of the hydraulic cylinder is fully extended or retracted.
5) When the hose vibrates violently, stop the operation of the hydraulic hammer and check the pressure of the accumulator.
6) Prevent the excavator boom from interfering with the hydraulic hammer bit.
7) Do not immerse the hammer in water except the drill bit.
8) The hydraulic hammer shall not be used as a spreader.
9) Do not operate the hammer on the track side of the excavator.

10) When the hydraulic hammer is installed and connected to the excavator or other construction machinery, the working pressure and flow of its host system must meet the technical parameters of the hydraulic hammer. The “P” port of the hydraulic hammer is connected to the high-pressure oil circuit of the host, and the “a” port is connected to the return oil circuit of the host.
11) The oil temperature of hydraulic hammer is 50-60 ℃, and the oil temperature shall not exceed 80 ℃. Otherwise, reduce the load of the hammer.
12) The working medium used by the hydraulic hammer can generally be consistent with the oil used by the host system. Yb-n46 or yb-n68 anti-wear oil is recommended in general areas, and yc-n46 or yc-n68 low temperature oil is recommended in cold areas. The filtering accuracy shall not be less than 50 microns;
13) The newly repaired hydraulic hammer must be charged with nitrogen, and the pressure between the drill pipe and the cylinder guide rail is 2.5 and 0.5MPa
14) Calcium base grease or compound calcium base grease must be used for lubrication, and each unit shall be added once.
15) When the hydraulic hammer works, the drill pipe must be pressed on the rock and maintained at a certain pressure before starting the hydraulic hammer. It is not allowed to start under the suspended state.
