Using your Wolfcraft self - priming pump is a breeze. First, make sure you have a standard power drill with at least 600W. Connect the pump to the drill according to the instructions. Then, attach a hose with a 13 mm diameter to the pump. Place the suction end of the hose into the liquid you want to move, like in a water bed or water butt. Turn on the drill, and the pump will start working right away. When using, keep in mind that the suction height should not exceed 3 m and the delivery height should be within 15 m. Also, make sure the drill is working properly. For maintenance, after each use, disconnect the pump from the drill and the hose. Clean the pump with clean water to remove any debris or residue. Store it in a dry place. If you notice any issues, like a decrease in flow rate, check for blockages in the hose or pump. This way, your pump will last a long time and keep performing well.
