6.1 Tire Inflation (Air Compressor Function)

Image: The ST-5537 in use, inflating a car tire. The digital display shows pressure, and the LED light is active. This image also illustrates the automatic stop feature.
- કનેક્ટ કરો: Attach the air hose with the correct nozzle to the tire valve. Ensure a tight connection to prevent air leakage.
- પાવર ચાલુ: Press the power button to turn on the device. The digital display will show the current tire pressure.
- મોડ પસંદ કરો: Press the mode button to cycle through different inflation modes (e.g., car, motorcycle, bicycle, ball). Each mode may have a default pressure unit (PSI, BAR, KPA, KG/CM²).
- લક્ષ્ય દબાણ સેટ કરો: Use the '+' and '-' buttons to set your desired target pressure. Refer to your vehicle's manual or tire sidewall for recommended pressure.
- ફુગાવો શરૂ કરો: Press the power button again to start the compressor. The device will automatically stop once the target pressure is reached.
- ડિસ્કનેક્ટ કરો: Carefully disconnect the nozzle from the tire valve. A small amount of air may escape, which is normal.
Note: For car tires, the default BAR unit in car mode might be unfamiliar. You can switch to bicycle mode to set pressure in PSI if preferred, then inflate your car tire.
