Valve Type
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.
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.
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.
