R250 Preset CO2 with Pressure Presta Socket Inflator, Black/Red, Gauge,

---------------------------------------------------------------------- 【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer.

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- CO2 cylinder inflator with air pressure gauge With previous CO2 inflators, it was sometimes unsettling because you didn't know how much CO2 would be added. Once you have set the maximum value (PSI or BAR) using the dial on the main unit, all you have to do is slowly turn the flow adjustment knob to ON. Do not turn it all the way in one go like with previous CO2 inflators; instead, add the fluid little by little. The idea is to pour it all the way in for about 6 to 10 seconds. Align the air pressure preset knob with the center line. CO2 cylinders have a limited capacity. Even if you set the air pressure higher, a standard 16g cylinder will not hold that much CO2. Tires and rims have become wider recently, so 7 bars cannot fit in tires like the old 15mm inner width/old ETRTO 700x23c tires from two decades ago. If one CO2 cylinder does not provide enough pressure, use a second CO2 cylinder.
