Device is used to pump water of a redemption at night. At first I did not know in which direction to Run the drill, so that the water comes up. After about 30 minutes I caught on only that one can turn the drill 1 minute, until the water is pumped up. Here is to the instructions, you should not pump longer than 30 seconds to run dry. Otherwise, when the pump is running, the water is pumped up very quickly.
