Operation Instruction

1. Park the vehicle in a safe position and ensure it is safely parked before using the air compressor.
2. Long press the power button to turn on the product. When using an external power supply, ensure it is stable and has a power output greater than the product's requirement (DC 12V only).
3. Connect the threaded end of the air pipe to the product's outlet and tighten it. Then, connect the air nozzle to the tire valve, ensuring a tight seal without leaks.
4. The current tire pressure will be displayed when connected. Set the desired pressure value using the '+' or '-' buttons. Press 'R' to select the air pressure unit or scene.
5. Once the preset pressure value is set (and is higher than the current tire pressure), press the power button to start inflating. The product will automatically stop when the preset pressure is reached.
6. After inflating, remove the air nozzle from the tire first, then disconnect the air pipe from the product. The product will enter hibernation after a period of inactivity. Long press the power button to wake it up for subsequent use.
7. Use the accessory air nozzle for inflating other items like balls and inflatable toys.
8. When the battery capacity indicator is red and blinking, the product is low on power and requires charging. Use the provided charger; do not use other chargers.
9. If the battery is too low, connect the product to a DC 12V cigarette lighter socket (≥ 60W) using the provided external power cord to continue use. Charge the air compressor as soon as possible after use.
10. For long-term storage, turn on and charge the air compressor once a month to maintain the built-in lithium battery.

Precautions

• Charge the air compressor before use. If the battery capacity is low, connect to a DC 12V (≥ 60W) power supply to continue use.
• Only use a 12V DC power supply with a power output greater than 60W when connecting to an external power source. Using other power supplies may damage the product.
• The product generates heat during operation due to its compact design. The internal temperature and air pipe can become very hot. Avoid touching the air pipe during use to prevent scalding.
• For continuous use, allow the product to cool down for 10-15 minutes after every 8-10 minutes of operation to extend its lifespan.
• Never leave the air compressor unattended while in operation, as it is an electrical tool.
• This product should not be used by children or individuals with disabilities to prevent injury.
• Avoid using the air compressor in humid or desert environments to prevent water or dust from entering and damaging internal components.
• Do not expose the product to extreme conditions such as high/low temperatures, humidity, dust, or flammable/explosive environments.
• Do not discard the product; recycle it at designated recycling points.

Warm Prompt

• Check tire pressure before starting your car and replenish when insufficient.
• When using the air compressor on the roadside, park the vehicle in a safe and stable location.
• Ensure surrounding warning signals are in place when parked on the roadside to alert other vehicles and pedestrians.
• Charge the product promptly after use. If not in use for extended periods, charge it once a month.
• If the product does not respond when connected to an external power supply, check the fuse in the external wiring plug and replace if necessary.

Product Specification

• Rated Voltage: DC 7.4V / DC 12V (selectable)

Battery Capacity

• Fully Charge: The battery is fully charged.
• Low Battery Capacity: Charge the product or switch to external power supply when the battery is low.
• Low Battery Protection: The product will stop output and cut off power when the battery capacity is critically low. External power is required for continued use.
• Charging: Use only the product's own charging cable. Do not use the product while charging to avoid damage. Connect the charging cable to a USB port for charging.
• Charging Cable Specification: The micro current charger class greatly protects battery life and takes 5-8 hours to fully charge.
• Charger Warning: Strictly forbidden to use any other charger to charge the product.

Operation Interface

The product features the following controls:

• Power Switch: Turns the device on/off.
• Pressure + / - : Adjusts the preset pressure value.
• R (Mode/Unit): Selects air pressure unit or scene mode.
• Light: Turns on the LED light.
• Display: Shows current tire pressure, preset pressure, and battery capacity.

External Power Supply (Optional): The external power input port is located at the bottom of the product. Connect the other end to the car cigarette lighter socket.

Tips for Small Details of Product Operation

• Anti-Miscontact Function: The air compressor automatically stops working if the pressure is 0 for an extended period while operating.
• Hibernation Function: The air pump enters hibernation mode after a period of inactivity. Long press the charging control button to wake the system.
• External Power Use: When the battery is depleted, external power (DC 12V) can be used for continued operation.

Main Problem Solution

1. Digital air compressor cannot work properly: Ensure the preset pressure value is higher than the current display pressure for inflation to function.
2. Unstable power supply / disconnection: Check the cigarette lighter plug's contact with the car socket. Clean the socket and gently pry open the metal sheets on the plug for better contact.
3. No power after powering on: Unscrew the metal nut on the power plug, check the fuse, and replace it if necessary. Screw the nut back securely.
4. Product becomes very hot: High temperature is normal due to air compression. If too hot, stop the product for 10-15 minutes of cooling. For continuous use, cool for 15 minutes after every 6-10 minutes of operation.
5. Stops working immediately after connecting to tire, displays very high value: Check if the air pipe and tire are properly connected and if there are any blockages. Ensure the tire air valve cap is removed and the connection is secure until an air leak sound is heard. Remove any limiting devices on the tire valve.
6. Air pressure is not accurate: The product is calibrated at the factory with minimal tolerance. Small discrepancies with other testing devices are normal and do not affect car driving. The tolerance between test props and standard pressure is usually within 0.2 bar.
7. Other problems: Please contact SYTUNG after-sales service.
