Familiarize yourself with the components of your air compressor:

• Power Cable: Connects to 12V DC power outlet.
• Air Hose: Connects to the item being inflated.
• Pressure Gauge: Displays current pressure.
• ON/OFF Switch: Activates and deactivates the compressor.
• LED Flashlight: Provides illumination.
• Nozzle Storage: Integrated storage for the included adapters.

5. Setup

1. Prepare the Compressor: Uncoil the power cable and air hose. Ensure the ON/OFF switch is in the "OFF" position.
2. Select Nozzle: Choose the appropriate inflation nozzle for the item you intend to inflate. The compressor comes with 3 different nozzles for various applications (e.g., needle for balls, tapered nozzle for air mattresses, screw-on adapter for tires).
3. Attach Nozzle: Securely attach the selected nozzle to the end of the air hose.
4. Connect to Power: Insert the 12V power plug into your vehicle's cigarette lighter socket or other compatible 12V DC power outlet. Ensure a secure connection.

6. Operating Instructions

1. Connect to Item: Attach the nozzle firmly to the valve stem of the item you wish to inflate. For tires, ensure the screw-on adapter is tightly secured to prevent air leakage.
2. Check Pressure: The pressure gauge will display the current pressure of the item. Note the recommended pressure for your item (usually found on the tire sidewall, vehicle door jamb, or item's manual).
3. Start Inflation: Flip the ON/OFF switch to the "ON" position. The compressor will begin to operate and inflate the item.
4. Monitor Pressure: Continuously monitor the pressure gauge. The compressor features an automatic shut-off function once the desired pressure is reached, but manual monitoring is always recommended.
5. Stop Inflation: Once the desired pressure is reached, or if you need to pause, flip the ON/OFF switch to the "OFF" position.
6. Disconnect: Carefully disconnect the nozzle from the item's valve stem. Some air may escape during disconnection, which is normal.
7. Disconnect Power: Unplug the 12V power cable from the power outlet.
8. Using the LED Flashlight: The integrated LED flashlight can be activated independently using its dedicated switch, providing illumination during low-light conditions.

Note: For optimal performance and to prevent overheating, allow the compressor to cool down for 10-15 minutes after every 10 minutes of continuous operation.

7. Maintenance

• Cleaning: Wipe the exterior of the compressor with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the compressor is unplugged before cleaning.
• Storage: Store the compressor in a cool, dry place, away from direct sunlight and extreme temperatures. Coil the power cable and air hose neatly to prevent damage. Store nozzles in their designated compartment.
• Inspection: Periodically inspect the power cable, air hose, and nozzles for any signs of wear or damage. Do not use if any components are damaged.
