- Remove the valve cap from the tire you wish to inflate.
Operating Instructions
Follow these steps to inflate your tires:
- Connect to Tire Valve: Firmly screw the quick-connect air hose onto the tire valve stem. Ensure a tight seal to prevent air leakage. The digital display will show the current tire pressure.
- Set Desired Pressure: Use the '+' and '-' buttons on the inflator to set your desired target pressure (PSI). Refer to your vehicle's owner's manual or the sticker on the driver's side door jamb for the recommended tire pressure.
- Start Inflation: Press the power button (usually marked with 'O' or a power symbol) to begin inflation. The inflator will start pumping air, and the digital display will show the increasing pressure.
- Automatic Shut-Off: The inflator will automatically turn off once the preset target pressure is reached.
- Disconnect: Unscrew the air hose from the tire valve stem and replace the valve cap.
- Repeat: Repeat the process for all other tires requiring inflation.
- Using Adapters: For inflating sports balls, rafts, or other inflatables, attach the appropriate adapter to the air hose before connecting to the item.
