Q. How to use bicycle air pumps?

Answer

Establish the recommended tyre pressure. On each tire's side wall, there is a suggested pressure range.Verify that your pump and the sort of valve on the tyres are compatible. Most pumps are suitable with both Schrader and Presta valves, which are found on all tyres. You can buy a converter at your neighbourhood bike store if your pump isn't.Take off any dust caps on your valves.You're ready to start pumping if you're using a Schrader valve!If you have a Presta valve, open it by unscrewing the end. By pushing the valve core inside, you may determine whether it is sufficiently loose. You are prepared to move if you experience a surge of air.To firmly attach the pump to the valve, press the pump head as far as it will go against the valve. Lift the lever to lock the head after that.Move the head about. The valve must be pushed downward even further if you can feel it moving within.Start pumping after the pump has been firmly fastened. When you pump, if you notice air hissing out, the head is still not secured enough. Go back to step 7 and try one more.As you pump, pay attention to the pressure gauge. When you are inside the range shown on the sidewall of your tyre, stop pumping.To remove the pump head from the valve, immediately pull it off by depressing the lever. Don't forget to close your Presta valve if you're using one.Push the pump head as far as it will go down just on the valve to secure the pump to the valve. Lift the lever to lock the head after that.
