Youin MA1018 Portable Electric Air Compressor

Product Information

The Portable Electric Air Compressor is a compact and useful product designed for emergency pumping of high-pressure tires forracing bicycles. It can also be used for inflating ordinary bicycles, cars, motorcycle wheels, and balls. The product comes with an LCD display, preset air pressure modes, work light and SOS police light, and a USB charging cable. The product is resistant to rain, water, and impact.

Product Usage Instructions

1. Charge the product for 4 hours before first use.
2. Press the power button until the LCD display shows the desired air pressure unit (PSI, BAR, or KPA).
3. Select the desired air pressure mode (basketball 8 PSI, motorcycle 28 PSI, car 35 PSI) using the mode button.
4. Connect the inflatable tube and inflatable accessory connector to the air compressor and the object to be inflated.
5. Press the power button to start inflation. The compressor will stop automatically when the inflation pressure reaches the set value.
6. If the air pump detects no air pressure, it will automatically stop running for about 40 to 50 seconds.
7. When inflation is complete, unscrew the air tube from the inlet port of the object. There will be a small air leak when removingthe connector, which is normal.
8. If the tire pressure is deemed too high, use the tire inflation connector to screw it into position on the valve core to deflate and reduce pressure.
9. After use, unscrew the tire inflation connector from the main motor and store the compressor in its original packaging in a dry,ventilated, and safe place.

Instructions for use

1. The first normal charging time is 4 hours.

2. Press the power button until the LCD display starts to show. Short press the setting key to switch between PSI, BAR, KAP, KG/CM² air pressure units. When the air pressure value stops flashing, you can start inflation by short pressing the power button.

3. The different inflation modes are selectedusing the setting key; they are programmed with standard parameters for optimal use:

   • Default Motorcycle Mode: 28 PSI
   • Default Bicycle Mode: 120 PSI
   • Default Car Mode: 36 PSI
   • Default Ball Mode: 8 PSI

4. Define and set the air pressure value yourself.
   You can short or long press ‘+’ or ‘–’ to adjust the preset pressure value more precisely and/or quickly.

5. Press the power button to start inflation.
   When the inflation pressure reaches the set value, the compressor will stop the process automatically.

6. When the air pump starts to detect no air pressure, it will automatically stop running for about 40 to 50 seconds.

7. When inflation is complete, unscrew the air tube from the inlet port of the object. There will be a small air leak when removing the connector, which is normal.

8. If the tyre pressure is deemed to be too high, you can use the tyre inflation connector to screw it into position on the valve core to deflate and reduce the pressure.

9. When you have finished using it, unscrew the tyre inflation connector from the main motor.
   Store the compressor in its original packaging in a dry, ventilated and safe place.

Preventive Tips

• Keep the product out of reach of children.
• Do not use the product near flammable and explosive liquids and gases.
• Do not walk away during the inflation process, and let the machine stand still for 10 minutes after continuous use.
• If there is abnormal noise or the temperature is too high during inflation, turn off the machine immediately and let it cool down for at least 15 minutes. Be careful when removing the connector from the inlet port.
• If the compressor is stored for a long period, charge it for 4 hours once every three months.
• During the charging process, the battery display and the bar will flash; once the charging is complete these elements will remain set.
