3. Connecting the High-pressure Air Hose and Nozzle Schrader Valve Tires on cars, motorcycles, e-bikes, and most mountain bikes use a Schrader valve. To inflate: The air compressor can be directly connected to a Schrader valve to start inflating. To deflate: Use an appropriate tool to press the pin inside the air valve to release air. Presta Valve Adapter Road bicycles and certain mountain bikes use a Presta valve which requires the included Presta valve adapter to be used. To inflate: Unscrew the Presta valve's ring, attach the Presta valve adapter to the air hose, and connect the air compressor to the tire's valve to start inflating.
After the tire is inflated, screw the valve's ring back down. To deflate: Unscrew the ring of the Presta valve, and press the valve stem down to release air. Needle Valve Adapter To inflate balls like basketballs and footballs, the included needle valve adapter will need to be used. To inflate: Screw the needle valve adapter onto the Schrader valve adapter, then insert the needle into the valve of the ball to start inflating. To deflate: Insert the needle valve adapter into the valve of the ball, and gently apply pressure to the ball to release air. 18 Valve Type Valve Type Valve Type 1 pa2r sb i 8.0
