As well as using this Azur ‘Air Tank’ Tubeless Floor Pump as a regular pump, it is also able to pump tubeless tyres quickly and effortlessly using its air tank feature. A large 6.35cm easy-to-read dial gauge is conveniently located at the top of the aluminium alloy barrel. Just follow these easy steps: For standard tyre inflation turn the small lever on valve head to ‘For Tyre’ position and use the pump as a normal. To inflate a tubeless tyre, turn the small lever to ‘For Tank’ position and charge to 240psi. Then quickly turn the lever back to the ‘For Tyre’ to release the air into the tubeless tyre. Once the air in the tank has been released, pump the tyre to its recommended pressure.
