Setup

Follow these steps to prepare your air compressor for use:

1. Ensure the power switch on the compressor is in the OFF (O) position.
2. Start your vehicle's engine. This provides sufficient power for the compressor and prevents battery drain.
3. Plug the compressor's power cord directly into your vehicle's 12V DC cigarette lighter socket.
4. Remove the dust cap from the tire valve.
5. Attach the air chuck connector firmly to the tire valve stem by screwing it on. Ensure a tight seal to prevent air leakage.

Operating Instructions

This section details how to operate your EPAuto air compressor for tire inflation.

Setting Desired Pressure:

• Press the (M) button on the digital display to cycle through the available pressure units: PSI, KPA, BAR, KG/CM².
• Use the (+) or (-) buttons to set your desired tire pressure. The display will flash while you are setting the pressure. Once you stop adjusting, it will stop flashing, indicating the set pressure is locked in.

Inflation Process:

1. Once the desired pressure is set, move the power switch to the ON (-) position to start the compressor.
2. The compressor will automatically stop inflating when the set pressure is reached.
3. After inflation, move the power switch back to the OFF (O) position.
4. Unscrew the valve connector from the tire valve stem and replace the dust cap.
5. Unplug the power cord from the 12V cigarette lighter socket.
