The second step,Wearing a mask

First fasten the long strap of the mask, make the mask mouth and nose cover completely fit the face with one hand, and pull the headband back to cover the head with the other hand to tighten the headband. It must be remembered here that those who cannot ensure the airtightness of the mask are not allowed to use air respirators, such as beards, sideburns, glasses, and scars on the face. Finally, test the airtightness of the mask and disconnect the air supply valve. If the breathing is smooth, the mask is unqualified or worn incorrectly. Otherwise, the air respirator mask is well sealed.

The third step, connect the supply and demand valve

Open the gas cylinder valve to the end and see if the alarm whistle sounds briefly. At the same time, look at the respirator pressure gauge to check the inflation pressure. Finally, connect the supply and demand valve interface with the mask, so that we can use it normally.
