6. Operating Instructions

6.1 Jump Starting a Vehicle

1. Step 1: Insert the smart clamp plug firmly into the starting output port on the Utrai JS-40.
2. Step 2: Connect the red (+) clamp to the positive terminal of the car battery and the black (-) clamp to the negative terminal of the car battery.
3. Step 3: Start the car engine. If the engine does not start immediately, you may use the force start mode by pressing and holding the button on the clamp plug for 3 seconds.

6.2 Using the Air Compressor (Inflate/Deflate)

The JS-40 features 6 preset modes for various inflation needs (Car, Motor, Bicycle, Ball, Custom, Blower) and an auto shut-off function.

1. Step 1: Insert the air hose into the Inflate/Deflate port on the device and connect the appropriate nozzle to the item you wish to inflate or deflate.
2. Step 2: Short press the power button (U) to turn on the device. Press the Mode button (M) to select the desired mode (e.g., Car, Motor, Bicycle, Ball, Custom, Blower). Use the plus (+) and minus (-) buttons to adjust the preset pressure if necessary.
3. Step 3: Long press the power button (U) to start inflation or deflation. The device will automatically stop when the preset pressure is reached (for inflation) or when the process is complete (for deflation).

6.3 Using as a Power Bank

The Utrai JS-40 can charge your electronic devices with its 10000mAh battery and PD30W fast charging capabilities.

• Always keep the JS-40 charged, especially before long trips, to ensure it's ready for emergencies.
• Familiarize yourself with the different inflation modes and pressure units (PSI, KPA, BAR) to quickly select the correct setting.
• When jump starting, if the vehicle doesn't start on the first attempt, wait a few minutes before trying again to allow the JS-40 to cool down slightly.
