Failure analysis:

After disassembling the hammer rock breaker, the repairer found that there were spots on the piston, and it was obvious that rust had appeared, which was also the direct cause of the oil leak. After careful inquiry, I learned that the original owner did not release the nitrogen in it in time after hitting the breaker because he did not perform construction during the epidemic.
