Important Safety Information
Always follow basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, and personal injury.
- Ensure the vehicle engine is running when operating the compressor to prevent draining the car battery.
- Do not leave the compressor unattended during operation.
- Keep out of reach of children.
- Avoid prolonged continuous operation. Allow the compressor to cool down after 10-15 minutes of use to prevent overheating.
- Do not operate the compressor in wet conditions or near flammable liquids or gases.
- Always check the recommended pressure for your tires or inflatables to avoid over-inflation.
- If the compressor makes unusual noises or becomes excessively hot, turn it off immediately and disconnect it from the power source.
- Use only the provided accessories and attachments.

Operating Instructions
Inflating Vehicle Tires:
- Start Vehicle Engine: Turn on your vehicle's engine to provide stable power to the compressor.
- Connect Power: Plug the 12V DC cigarette lighter plug into your vehicle's power socket. The digital display should illuminate.
- Set Desired Pressure: Press the 'M' button to select your preferred pressure unit (PSI, KPA, BAR, KG/CM²). Use the '+' and '-' buttons to set the target tire pressure. Refer to your vehicle's manual or tire sidewall for recommended pressure.
- Turn On Compressor: Before attaching the air hose to the tire valve, turn on the compressor using the power switch. This prevents the motor from starting under load, which can blow the fuse.
- Attach Air Hose: Screw the air hose connector firmly onto the tire valve stem. Ensure a tight seal to prevent air leakage.
- Monitor Inflation: The compressor will begin inflating and the digital display will show the current tire pressure. It will automatically shut off once the preset pressure is reached.
- Disconnect: Once inflation is complete and the compressor has shut off, turn off the compressor's power switch, then unscrew the air hose from the tire valve. Disconnect the 12V power plug from your vehicle.

Using the LED Light:
The compressor is equipped with an LED light for illumination in low-light conditions. Simply use the dedicated light switch located on the side of the unit to turn it on or off.

Inflating Other Items (Balls, Air Cushions, etc.):
- Select Adapter: Choose the appropriate nozzle adapter for the item you wish to inflate.
- Attach Adapter: Screw the selected adapter onto the air hose connector.
- Insert Adapter: Insert the adapter into the item's inflation port.
- Inflate: Follow steps 1-4 and 6-7 from the "Inflating Vehicle Tires" section, adjusting the target pressure as needed for the specific item.

Maintenance
- Cleaning: Wipe the compressor with a damp cloth after use. Do not use harsh chemicals or immerse in water.
- Storage: Store the compressor and its accessories in the provided carry bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Fuse Replacement: If the compressor stops working, check the fuse located inside the 12V cigarette lighter plug. Unscrew the tip of the plug to access and replace the fuse with the spare provided (or a compatible 15A fuse).
- Air Filter: Periodically check the air intake filter (if accessible) for dust and debris. Clean or replace as necessary to maintain optimal performance.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | 1. No power from 12V socket. 2. Blown fuse in 12V plug. 3. Vehicle engine not running. | 1. Check vehicle's 12V socket for power. Try another socket if available. 2. Replace the fuse in the 12V plug. (Refer to Maintenance section). 3. Start the vehicle engine. |
| Compressor inflates slowly or not at all. | 1. Air hose not securely attached. 2. Low voltage from vehicle. 3. Clogged air filter. | 1. Ensure air hose is tightly screwed onto the valve stem. 2. Ensure vehicle engine is running and battery is charged. 3. Check and clean the air filter. |
| Digital gauge reading is inaccurate. | Minor calibration difference. | It is common for digital gauges to have slight variations. If you have a trusted external gauge, you can adjust the target pressure on the compressor by 1-2 PSI higher or lower to match. |
| Compressor overheats and shuts off. | Prolonged continuous use. | Allow the compressor to cool down for at least 10-15 minutes before resuming operation. Avoid continuous use for more than 10-15 minutes. |
