5. Use Guide

5.1 Initial Setup and Charging

1. Unpack the compressor and all accessories.
2. Connect the provided charging cable to the charging port on the compressor and to a standard USB power adapter or port.
3. Charge the unit fully for 3-4 hours before first use. The battery indicator on the display (if present) will show the charge status.

5.2 Setting the Target Pressure

1. Press the power button to turn on the display.
2. Use the unit button (marked as "Unit" or similar) to select your preferred pressure measurement: PSI, BAR, KPA, or KG/CM².
3. Use the "+" and "-" buttons to set your desired target pressure. The target value will be shown on the display.
4. Reference: Standard car tire pressure is typically between 30-35 PSI. Check your vehicle's placard (usually on the driver's door jamb) for the correct pressure.

5.3 Inflating a Tire

1. Remove the valve cap from the tire's valve stem.
2. Firmly press the inflator nozzle onto the valve stem. You may hear a brief hiss of air; ensure the connection is secure to prevent air leakage.
3. The display will show the current tire pressure.
4. Press and hold the power/start button to begin inflation.
5. The compressor will run and stop automatically when the preset target pressure is reached.
6. Remove the nozzle from the valve stem and replace the valve cap.

5.4 Using the LED Light

Press the LED light button to cycle through the modes: Flash Light -> Alarm Light -> SOS Light -> Off. Hold the button to turn the light off.

5.5 Inflating Other Items

Attach the appropriate nozzle or adapter from the included kit to the end of the air hose for inflating bicycles, balls, or other inflatables. The auto-shutoff function will still operate if the item has an airtight seal with the nozzle.

6. Safety and Maintenance

6.1 Safety Warnings

• Do not use the compressor to inflate persons or animals.
• Do not point the air stream at people or eyes.
• Do not operate the compressor in a wet environment or submerge it in water.
• Keep the compressor away from heat sources and open flame.
• Do not block the air intake or exhaust vents during operation.
• Observe the 10-minute run / 10-minute cool-down cycle to avoid motor damage.
• Check the tire's maximum pressure rating (on the sidewall) and do not exceed it.

6.2 Care and Storage

• Store the compressor and accessories in a cool, dry place.
• Keep the air hose and nozzles clean and free of debris.
• If the battery will not be used for an extended period, charge it to approximately 50% before storage.
• Use only the provided or manufacturer-approved charging cable.

6.3 Troubleshooting

• Compressor won't turn on: Ensure the battery is charged. Connect to the charger.
• Compressor stops quickly: The battery may be low. Recharge the unit.
• Pressure reading is inaccurate or zero: Check that the nozzle is securely connected to the tire valve. There may be a leak in the connection.
• Compressor does not auto-shutoff: Verify the target pressure is set correctly. The seal on the item being inflated may not be airtight.
• Unit becomes very hot: Stop use immediately and allow it to cool down. You may have exceeded the recommended continuous run time.
