The stored air is unsafe to breath and can be flammable. Always release the air outdoors, away from other people. Keep your clothing, hair, and jewelry away from the tank’s hose. Also, keep the tank away from open flames. For their safety, avoid letting children operate the tank. Slide the air hose over the brass fitting near the pressure gauge. It should fit on the opposite end of the small, ringed spout you used to fill the tank. Connect the hose’s other end directly to the item you wish to inflate. An air hose usually is included with the tank when you purchase it. You can get new hoses at home improvement or auto parts stores. Look near the brass fitting to find a small, handy wheel. Turn the wheel counterclockwise to open the tank’s valve. You should hear air flowing out of the tank right away. Air will continue to flow until you close the valve again. Watch the inflatable object closely to ensure it is filled at a safe level. Over-inflated items are liable to burst. When an item is inflated to the correct size, it will feel firm to the touch. It should not bulge or appear near bursting. Listen closely for any hissing coming from the tank, since this indicates that air is still flowing. Make sure the valve is closed completely. When you’re ready, detach the hose to release any air stuck inside of it. If you plan on storing the tank for a while, stay safe by letting all the air out of it.
