On the COASTAL DRILLER, a noticeable increase in the level indicator while extracting the legs from the soil indicates _______________.
AI Explanation
The correct answer is A) one or two legs are stuck.
A noticeable increase in the level indicator while extracting the legs from the soil on a COASTAL DRILLER indicates that one or two of the legs are stuck in the soil. This is because the stuck leg(s) would require more force to extract, causing a rise in the level indicator as the legs are pulled up.
The other answer choices are incorrect. B) and C) describe a punch-through event, which would not necessarily cause a noticeable increase in the level indicator. D) the legs are free is incorrect, as the increase in the level indicator signifies that the legs are not freely extracting from the soil.
