6. Usage Guide

6.1 Inflating with Internal Battery (Cordless Mode)

1. Set Target Pressure: Press the Power button to wake the display. Use the '+' and '-' buttons to set your desired pressure (e.g., 35 PSI for a car tire). Use the UNIT button to select PSI, BAR, or KPA.
2. Attach Hose & Nozzle: Screw the appropriate air hose onto the unit's connection port. Attach the required nozzle or adapter to the other end of the hose (e.g., standard Schrader nozzle for car tires).
3. Connect to Valve: Remove the valve cap from the tire or item. Firmly press the nozzle onto the valve stem until you hear a slight hiss, indicating a seal. Lock the lever if your nozzle has a locking mechanism.
4. Start Inflation: Press and hold the Power/Start button. The digital display will show the rising current pressure. The inflator will run loudly.
5. Auto Shut-Off: The inflator will automatically stop when the preset target pressure is reached.
6. Disconnect: Quickly remove the nozzle from the valve stem and replace the valve cap.
7. Press the Power button to turn the unit off.

6.2 Inflating with 12V DC Car Power (Corded Mode)

1. Ensure your vehicle's engine is running to avoid draining the car battery.
2. Plug the included 12V DC power cord into your vehicle's cigarette lighter/power outlet.
3. Plug the other end into the 12V DC input port on the inflator. The unit will now draw power from the vehicle, preserving its internal battery.
4. Follow steps 1-7 from section 6.1 to set pressure and inflate.

6.3 Using Different Adapters

• Presta Valves (Bicycles): Use the Schrader-Presta adapter. Screw the adapter onto the Presta valve before attaching the standard hose nozzle.
• Needle Valves (Balls, Toys): Use the needle valve adapter. Attach it to the air hose, then insert the needle into the ball's valve.
• Extension Nozzle: Use for hard-to-reach valves or to provide a better angle.

7. Care & Maintenance

• Storage: Store the inflator and all accessories in the provided carrying bag in a cool, dry place.
• Cleaning: Wipe the exterior with a dry cloth. Do not use liquids or submerge the unit.
• Hose & Nozzles: Keep the air hose and nozzles clean and free of debris to ensure a proper seal.
• Battery: For long-term storage, charge the battery to approximately 50% and recharge every 3 months.
• Fuse Replacement: If the unit fails to power on in 12V DC mode, the fuse in the car power cord plug may be blown. Use the provided replacement fuse to swap it out.
