Deployment and adjustment methods
1) Use the settings wheel at the nape of the neck to adjust the optimum size of the headband.
2) Use the positioner beneath the headband holding screw on the right-hand side to adjust the distance
between your face and the hood. (item 14)
3) Attach the hose to the fi ltration-ventilation unit/compressed air system.
4) Fasten the screws on both left and right sides of the shield to a moment when the shield can easily move
up and down while stays in the upper position when opened.
5) Attach a hose to the welder's hood.
6) Check the tightness of the connection between the unit and the hood and also the operational status of the
PAPR. (Check, whether the operating pressure range is within the expected limits when using the
compressed air system.)
