Important Operating Instructions

Note: This product is only suitable for bicycles, motorcycles, scooters, and sports balls (basketball, soccer, rugby, volleyball); it is not suitable for cars, air mattresses, and other large inflatables.

Our hose is a newly designed Presta and Schrader 2-in-1 hose. The hose head has two parts. When fully tightened, it is suitable for Schrader. Unscrewing the head and pulling out the built-in brass fittings can adapt to Presta valves. Installing the Dunlop adapter in the tightened state is suitable for Dunlop valves.

If you notice inaccurate pressure readings or a sudden pressure spike that causes inflation to stop immediately when using this product with a Presta valve, it is due to the lock nut not being completely loosened, causing it to block the valve and prevent the pump from working properly. If you encounter these issues, please reconnect the hose and valve, ensuring that the lock nut is properly loosened to prevent pressure blockages that could hinder the product's operation.
