• Do not move the air compressor by pulling the air hose or power cord.
• PSI, Bar, kPa and kg/cm’ are pressure units, not the pressure levels.
• If pressure is below 40 PSI, the compressor’s maximum working time is 45 minutes. Allow the product to rest for at least 20 minutes after 45 minutes of continuous use.
• During continuous use, the air compressor may get hot. Let it cool down before storage.
• Connect the product to a (DC 12 V) 45 A vehicle battery.

PREPARATION

• When operating the air compressor, please ensure it is set up in a safe location.
• Place the air compressor on a dry, even surface.
• Unpack the package to check if there is any damage. Untie the power cord at full length.
• How to connect the¼” NPT quick connector to the air hose:
  1. Pull down the snap ring backwards.
  2. Connect the¼” NPT quick connector with the snap ring and secure them together.
  3. Release the snap ring to secure the connection.
     

INSTRUCTION

Note: Ensure the airflow controller has sufficient power before using the air compressor.

1. Securely connect the air hose to the¼” NPT quick connector of the air compressor, connect the other end of the air hose to the¼” NPT quick connector of the airflow controller.
   

2. Remove the valve stem cap from the tire stem, then connect the airflow controller”s quick connector to the valve stem.
   

3. Press the LCD Button to turn on the screen. Press it again to choose the desired unit. 4 options: PSI, Bar, kPa, kg/cm’.
   (Note: The screen will auto shutoff after 1 minute of no operation.)
   

4. Start the engine, open the hood, then connect the red clamp to the positive terminal of the vehicle’s 12 V battery, connect the black clamp to the negative terminal.
   

5. Pull the airflow valve downwards and switch the Power Button of the air compressor to the “I” side to start the air compressor.
   

6. Push the airflow valve upwards to stop the air inflow into the pressure gauge. Doing this reduces airflow pressure errors and B helps accurately measure the interior pressure value. After getting the pressure value, pull the airflow valve downwards to continue inflating (if needed).
   (Note: The air compressor continues inflating even if the airflow is blocked.)
   

7. When the pressure reaches the manufacturer-recommended level, press the Power Button to the “O” side and remove the air hose from the tire stem.
   (Note: Excessive inflation leads to high pressure inside the tires. Press the Deflate Valve to deflate the tire, and release the button to stop deflation.)
