1.Open the lid and fill with water, Fill enough water into the water gun.Pump the pressure pump back and forth multiple times, When enough pressure is injected, the water gun can squirt a greater distance.
As shown in the figure below, the small white hole on the water gun is the pressure release hole. Because both of these water guns can be electrically sucked to draw water from the gun to replenish the water inside, when the water in the water gun is full and you still try to suck water into the gun or the water pressure inside the gun is too high, the water inside the gun will leak out from this hole to prevent the excessive water pressure inside the gun from damaging it.
The water overflowing from this hole is not a quality issue of the product. It is the normal protection mechanism of the gun and a normal phenomenon.
2.Please make sure that the water in the water gun is pure water and not seawater or any other water containing impurities. Otherwise, it may damage the water gun and cause malfunction.
3.After using the product, please drain all the water from the water gun. Otherwise, the water inside the gun may corrode the product, causing functional abnormalities.
