Precautions are as follows: the operators must be trained by technical training to understand the structure principle and working performance of the DTH Drill, well know the operation rules and maintenance procedures of the DTH Drill, and be operated by the test. In addition, the operators should wear their work clothes. When the gun is fired, the equipment should be evacuated to a certain distance and cover up for protection.
In addition, it is not possible to carry out construction in bad weather. If the machine is shut down for a long time, the impactor should be put out of the hole, so as not to prevent the hole tower from blocking the drill bit. The cleaning, oil injection and repair work of the driving part of the DTH Drill must be carried out in a stop state. It should be often checked to check whether the joint is fixed or not, in case of disconnection. The maintenance work of the air supply system must be carried out after the wind stops.
