3) Crush solid objects by the bucket is not allowed, in case of large stones or hard objects, should continue the excavating job after removal them; Prohibiting excavation to the blasting rock with the hardness of more than five degree.

  4) Prohibit the excavator digging upper and lower two mining operation sites at one time; the ground should be flattened before the excavators move within the working surface, also need to clear the obstructions around.

5) Prohibit jacking up excavators with the method of stretching out the bucket cylinder fully. Before bucket leave the ground, the excavator can not transverse or move rotationally.

6) Prohibit using the excavator boom drag other things horizontally; hydraulic excavator can not use impinge mining methods to dig.

The driver should always pay attention while excavators working, if there is abnormal operation, should immediately stop running and overhaul, troubleshooting timely.

9) When the excavator operating, should often check the hydraulic oil temperature are normal or not.

11) During the excavator run-time, the boom should be parallelled with the running gear, turntables should be locked, bucket should keep at least 1meter away from the ground. Downhill running should use low gear, should prohibit sliding off stalls.

12) Excavator routes should keep away from with the slope, ditches, pit to ensure safety; when crossing soft land sections, should use low gear, if necessary, road padding can be added like wood, stones, etc.
