2. The position of the hammer breaker adjustment – when the hammer breaker cannot break the rock, it should be moved to a new hitting point.
3. The breaking operation shall not be operated continuously at the same position. The the temperature of chisel would rise when breaking at the same position for a long time. The chisel hardness would be reduced to damage the tip of chisel, thereby the operation efficiency cut down.
