HOW TO USE:
- Connect to Power: Ensure your vehicle or 12V DC power source can handle the 45A current draw. Securely connect the compressor’s power leads to the positive and negative terminals.
- Attach Air Hose: Connect an appropriate air hose to the 1/4″ (F)NPT outlet of the compressor, ensuring a tight connection to prevent air leaks.
- Set Desired Pressure: Set the desired output pressure if using an external regulator or for specific applications.
- Turn On the Compressor: Locate the power switch on the compressor and turn it to the “ON” position. The motor will start, and the tank will begin to fill with air.
- Monitor Pressure: Observe the built-in pressure gauge to track the air pressure inside the tank. The compressor will stop once it reaches the maximum pressure (120 PSI).
- Use Compressed Air: Utilize the connected air hose and accessories (e.g., tire chuck, air tool) for your intended application.
- Turn Off the Compressor: Once finished, turn the power switch to the “OFF” position.
- Release Excess Air (Optional): Follow the manufacturer’s instructions to release excess air from the tank for storage.
- Disconnect and Store: Disconnect the air hose and power leads, and store the compressor in a safe and dry place, ideally within an 18″ x 18″ toolbox.
