VI. Inflation Operation
- Connect the end with the flexible conduit adaptor of the hose to the air pump's inflation inlet and twist clockwise to tighten it (refer to Figure 1).
- Install the other end of the hose into the air bag's supporting air tap (refer to Figure 2). Twist clockwise to tighten, then insert the inflation valve of the air bag and twist clockwise to fix it (refer to Figure 2).
- After completing the above steps, press and hold the On/Off button ▶️ for 3 seconds for the display to light up. Short press the On/Off button ▶️ to start inflating. Press the On/Off button ▶️ for 3 seconds to stop working.
Pressure Setting:
- Press the pressure unit toggle button PSI/BAR ⑦ to select your desired unit.
- Press the pressurizing button ➕ ⑤ or decompressing button ➖ ④ to set the pressure value you need, ranging from 0 to 20 PSI (1 PSI = 0.0689 BAR = 6.89 KPA).
- During the inflation process, you can press the pressurizing button ➕ ⑤ or decompressing button ➖ ④ to increase or reduce the pressure value. Press the pressure unit toggle button PSI/BAR ⑦ to switch units and press the On/Off button ▶️ ⑥ to stop.
- Press and hold the On/Off button ▶️ ⑥ for 3 seconds to directly start the high pressure pump.
Notices:
- Upon completion of inflation, the pump will automatically turn off within 2 minutes without further operation.
- The air pump will stop working automatically when the set pressure value is reached.
- When not in use, please turn off the power switch, detach the hose from the air pump and air bag, and store it properly.
- The factory set pressure value of the air pump is 20 PSI. On subsequent uses, the pressure value from the last use will be displayed by default.
VII. Deflation Operation
- Remove the hose from the inflation inlet. Connect the end with the flexible conduit adaptor of the hose to the air pump's deflation outlet and twist clockwise to tighten it (refer to Figure 3). Ensure the other end remains connected to the air bag.
- In standby status, press the On/Off button ▶️ to start deflation. Continue until all gas is discharged, then press the On/Off button ▶️ for 3 seconds to stop working.
- When not in use, please take down the hose from the air pump air bag and store it.
VIII. Precautions
- The pump uses a Type-C USB (5V/2A or 9V/2A) for charging. The product shall not be operated while charging.
- Do not block the inflation inlet and deflation outlet; ensure they remain smooth at all times.
- Observe local waste treatment provisions. Do not discard the air pump randomly.
- Do not use this product if the hose is damaged; replace the hose immediately.
- Do not pull out the hose during inflation, as the high pressure may cause injury.
- Do not operate the air pump for more than 20 minutes continuously. Motor overheating may cause internal damage. Allow the pump to cool for 30 minutes after 20 minutes of continuous operation.
- If any part of this air pump is damaged, do not use it and contact professional personnel for repair.
- To prevent risk, do not point the inflation inlet towards your face or body.
- Do not leave the product unattended while inflating.
- Disposal: Do not dispose of this product as unsorted municipal waste. Waste must be collected separately for special disposal.
IX. Charging
The built-in batteries must be removed from the equipment and disposed of properly before scrapping.
Please fully charge the battery at least once every 6 months to ensure normal product use.
- Use the Type-C USB cable provided for charging. When charging, the indicators will flash. In fast charging mode, the red indicator ⚡ remains on. Charging voltage is 5V/2A or 9V/2A, which will be automatically identified (refer to Figure 4).
- Ensure the battery is fully discharged before the first charge. If the battery becomes hot after discharge, it is recommended to let it cool down before charging. Avoid leaving the electric air pump unpowered for extended periods.
