Setup
1. Initial Charging:

2. Connecting the Air Hose:
Screw the long air hose securely onto the air hose connection port of the inflator. Ensure it is tightened to prevent air leakage.

Operating Instructions
1. Powering On/Off:
Press and hold the Power button for 3 seconds to turn the device on. The digital display will illuminate. To turn off, press and hold the Power button again for 3 seconds.
2. Selecting Pressure Units:
After powering on, short press the Mode button to cycle through available pressure units: PSI, KPA, BAR, KG/CM².
3. Choosing Inflation Modes:
Short press the Mode button repeatedly to select one of the four preset inflation modes:
- Car Mode: Default pressure suitable for most car tires.
- Motorbike Mode: Default pressure for motorcycle tires.
- Bicycle Mode: Default pressure for bicycle tires.
