How to use the extended nozzle adapter
If your tires are flat, remove the screw-on cap from the valve, and connect the extended
nozzle adapter to the valve for pumping up.
1. Deflate the inner tire first. Use a tool to press the core rod in the air valve so that air is
discharged from the inner tire, and buse another hand to forcibly pinch the tire at
different places to discharge more air.
2. Select a position far from the air valve on the outer tire, use two crowbars to prize up the
outer tire by about 1/6 of the circumference, and forcibly separate one side of the outer
tire from the hub.
3. Find the air valve, and pull the air valve out of the air valve hole of hub. To pull out the air
valve more conveniently, hold the air valve of the inner tire, and pull the outer tire
outwards slowly, lest the inner tire would be damaged. Remove the inner tire from the
position of air valve in sequence, and separate the inner tire finally.
Note: Wrap the pointed end of the crowbar with fiber cloth so that it will not damage the
inner tire and coating of the hub.
