1. The parts of the breaker are severely worn or loose: Due to long-term use or abnormal use, the parts of the breaker may be worn or loose, causing abnormal noise in the breaker.
2. The pressure of the hydraulic system is unstable: The hydraulic breaker works through the hydraulic system. If the pressure of the hydraulic system is unstable, such as the pressure is too high or too low, it may cause the breaker to make abnormal noise.

3. Hydraulic oil is too dirty or too little: Hydraulic oil is a very important part of the hydraulic system. If the hydraulic oil is too dirty or too little, it will cause the breaker to have insufficient viscosity or excessive friction during operation, resulting in abnormal noise.
4. Poor working environment of the breaker: If the working environment of the breaker is poor, such as being used in muddy soil, foreign matter may invade into the interior of the breaker, resulting in abnormal noise.
