4. Inflation
Start inflation

Press “M”tart inflation. Digital displays real-time tire pressure during inflation. 75-80 dB noise will be generated during inflation, please pay attention to protect. The pump and air tube will generate high temperature when working continuously for a long  time, please avoid prolonged touching with hands.
Stop inflation

The air pressure reaches the preset value, the pump will stop inflation automatically. Press any key to stop inflation during inflation.

5. Battery and charging
   When the battery displays fully lit, it is fully charged. E flashing indicates battery low, It can be used after recharged. Don’t use the product when charging

6. Screw off the valve
   The temperature of tube is relatively high after inflation. Be careful burns when screwing off the valve.
   There will be slight air leakage when disassembly.
   Please remove it as quick as possible to reduce the air leakage.

7. Power off
   Press and hold the “On/Off”button to shut down.
   The air pump automatically shut down without any operation in 3 minutes in power on state.

8. Connection of various types of valve
   French valve adapter
   French valve will be used for road cycling and specific mountain cycling Inflation: Loosen the screw of French valve adapter to inflation.
   Deflation: Loosen the screw of French valve and press the screw to deflate
   Air Needle
   Basketball, football and other balls need to use air needle to inflation.
   Inflation: tighten the air needle and American valve and insert into the filling pore to inflation.
   Deflation: Insert the air needle in to the filling pore to deflation
   American valve
   Mountain cycling, electric bicycle, motorbike, automobile will be equipped American valve.
   Inflation: American valve can be directly connected to inflate.
   Deflation: Press the air needle inside the valve with a suitable tool to deflate.
   Multifunctional valve
   The multifunctional valve will be used for inflatable cushion, inflatable boat and balloon for inflation.
   Inflation: Tighten the multifunctional valve and American valve and insert into the filling pore to inflate.
   Deflation: insert the multifunctional valve into the filling pore to deflate.

9. Pressure examination
   Connecting with air tube, digital displays real-time pressure in power on state.

10. Inflation pressure check
    To ensure safety, please check the required inflation pressure of the inflated items by reading the manual before inflation.
    Ball
    The inflation pressure of football, basketball and volleyball will be marked around the valve.
    Tire pressure
    The tolerable range of tire pressure of automobile, bicycle and motorcycle are marked on the sidewall of the tires.
    The guide pressure of the tire is marked near the inner wall of the driver’s side door.The inflation pressure is related to the load weight. For more detailed air pressure suggestions, please refer to the vehicle manual.

Special reminder

The inflation pressure of balloon, toy ball, swimming circle and other products is lower than the range of inflation pump, so it can’t stop inflation automatically by preset pressure. Please use with caution.

Safety and protection

• stuck/high current protection: When there is a foreign body inside sticking the motor gear or the motor current is too high, the screen will display E21. The pump will resume normal after clearing the foreign body and reset or reset directly.
• Battery over discharge protection: When the battery is over discharged during inflation, the machine will start the over discharge protection, and the screen will display E22, restart or restart after charging will return to normal
• High temperature protection: When the internal temperature of the body is too high, the high temperature protection mechanism will be activated, the screen displays E23. After the temperature drops to the safe temperature, restart and return to normal.
• Inflation duration protection: After working at 25 ℃ for about 18 minutes, the inflation will stop automatically and the screen displays E25. restart and return to normal.
• Charing temperature protection: In the process of charging, when the lamp is on, it will enter into the charging temperature protection. When the temperature of standby is maintained at 0 ℃ ~ 45 ℃, it can be charged normally. During the charging  process, the lamp will go out automatically.

Note

1. This product is not a toy. Children are not allowed to use. It is recommended that the user should be over 16 years old. Keep children at a safe distance from the pump during inflation.
2. The product has built-in non detachable lithium battery. It is forbidden to throw into the fire or discard at will. There is a risk of fire, spontaneous combustion, explosion if lithium battery overheats, hits or waters. Please avoid exposure to the sun in high temperature environment such as in the car.
3. The storage temperature of the product should not be lower than – 10 ℃ or higher than 45 ℃. Supercooling or overheating will shorten the product life and damage the built-in battery.
4. The battery may be damaged if the product is idle for a long time. It is recommended to charge the battery at least once every three months.
5. The product has built-in DC motor, which may produce electric spark when working. Please do not use it in flammable and explosive environment.
6. In case of abnormal noise or high temperature, please shut down immediately.
7. Before setting the inflation pressure value, please make sure that the correct unit of measurement is selected, otherwise it may lead to tire burst and other accidents. Unit conversion：1bar=14.5psi，1bar =1000kPa。
8. Don’t leave during inflation and observe the inflation process to prevent the inflation pressure from being too high when the preset air pressure is not settled.
9. Please use in a dry and clean environment, the invasion of sand and dust may cause product damage. The product is not waterproof, do not wash with water.

Trouble Shooting

2.Check whether the tube leakage
3.Check whether the joints at both ends of the tube are tightened
4.Check whether there is air leakage in the inflated items
Turn on but cannot be inflated| 1.Is the electricity enough
2.Check whether the current tire pressure is higher than the preset value
3.When the internal temperature of the body is higher than 80 ℃, the protection will be opened  automatically (E23 is displayed).
The equipment return to normal operating temperature.
The preset pressure cannot be adjusted  up  or down| Check if in the incorrect profile. Select the range of 3-150psi without any icon on to adjust the preset value
Normal inflation but the pressure is zero| Low pressure inflatable products such as balloons are not within the measurable range of the  equipment
Unable to charge| When the body temperature is lower than 0 ℃ or higher than 45 ℃, the charging pump  enters the  state of charging temperature protection to keep the body temperature at 0 ~ 45 ℃
Air leakage when connecting the tube| Tighten the tube
The power display and standby state are  inconsistent in the inflation state| The voltage of power lithium battery decreases obviously during discharge, As a result, the power  display in the inflation state is inconsistent with the standby state which is not a fault.
