The correct operation method of hydraulic breaker

Read the operating manual of the hydraulic breaker carefully to prevent damage to the hydraulic breaker and excavator, and operate them effectively.
Before operation, check whether the bolts and connectors are loose, and whether there is leakage in the hydraulic pipeline.
Do not use hydraulic breakers to peck holes in hard rocks.
Do not operate the breaker when the piston rod of the hydraulic cylinder is fully extended or fully retracted.
When the hydraulic hose vibrates violently, stop the operation of the crusher and check the pressure of the accumulator.
Prevent interference between the boom of the excavator and the drill bit of the breaker.
Except for the drill bit, do not put the breaker into the water.
Do not use the crusher as a lifting device.
Do not operate the breaker on the crawler side of the excavator.
When the hydraulic breaker is installed and connected with the hydraulic excavator or other construction machinery, the working pressure and flow rate of the hydraulic system of the main machine must meet the technical parameter requirements of the hydraulic breaker, and the “P” port of the hydraulic breaker is connected with the main engine high-pressure oil circuit. The “O” port is connected to the return line of the main engine.
The best hydraulic oil temperature when the hydraulic breaker is working is 50-60℃, and the highest temperature should not exceed 80℃. Otherwise, the load of the hydraulic breaker should be reduced.
The working medium used by the hydraulic breaker can usually be the same as the oil used in the main hydraulic system.
The new repair fluid hydraulic breaker must be refilled with nitrogen when it is activated, and its pressure should be 2.5+-0.5MPa.
Calcium-based lubricating oil or calcium-based lubricating oil (MoS2) must be used for lubrication between the shank of the drill rod and the guide sleeve of the cylinder block, and it should be filled once per shift.
The hydraulic breaker must first press the drill rod on the rock and maintain a certain pressure before starting the breaker. It is not allowed to start in the suspended state.
It is not allowed to use the hydraulic oil breaker as a pry rod to avoid breaking the drill rod.
When in use, the hydraulic breaker and drill rod should be perpendicular to the working surface, based on the principle that no radial force is generated.
When the crushed object has cracked or started to produce cracks, the impact of the crusher should be stopped immediately to avoid harmful “empty hits”.
If the hydraulic breaker is to be stopped for a long time, the nitrogen should be exhausted, and the oil inlet and outlet should be sealed. Do not store it in a high temperature and below -20°C.
