The work of the breaker is mainly through the hydraulic system to promote the reciprocating movement of the piston. Its output strikes can make the work go smoothly, but if you have the breaker not strike or strike intermittently, the frequency is low, and the strike is weak. Where is it? 　　
1. The breaker does not have enough high pressure oil to flow into the breaker without hitting it. 　　 Reason: The pipeline is blocked or damaged; there is not enough hydraulic oil. 　　The treatment measures are: check and repair the supporting pipeline; check the oil supply system. 　　
2. There is enough high-pressure oil, but the breaker does not strike. 　　
3. The piston moves but does not strike. In this case, the main reason is that the drill rod of the breaking hammer is stuck. You can remove the drill rod to check whether the drill rod pin and the drill rod are broken or damaged. At this time, just observe whether the piston in the inner jacket is broken and the falling block is stuck. If there is any drill rod, clean it up in time.
