Second, before plugging in the impact drill, carefully check the insulation protection of the machine body. If the broken copper wire is found to be exposed, immediately wrap it with insulating tape to check whether the screws on the electric drill body are loose.
 
Third, install standard drill bits that are consistent with the permissible range of the percussion drill bit, and do not force the use of drill bits that exceed the range.
 
Fourth, when the percussion drill is energized, the wires should be well protected. They should not be dragged on sharp metal objects to prevent them from being damaged or cut. Don’t drag the wires into oil stains and chemical solvents to avoid corrosion of the wires.
