How to use:

Method 1: Inflate the air when the spring in the middle of the valve does not out (only inhale but not out)

Advantages: After the air is full, pull out the inflation tube, the air nozzle shrapnel will automatically close, and there will be no air leakage

Disadvantages: slow inflation speed, long time, abnormal noise may occur due to gas pushing the shrapnel

Method 2: Rotate the operating lever in the middle of the gas nozzle, and the other shrapnel is fully opened (inlet and out)

Advantages: fast inflation speed, short time, no abnormal noise

Disadvantages: After being fully charged, when the inflation tube is pulled out, a part of the air will leak because the air nozzle is in a fully opened state, until the operating lever in the middle of the manually rotating air nozzle is closed

Either way, after the air is full, the air nozzle and air nozzle must be screwed tightly to prevent air leakage
