NOTE: Air routing adjustments may be made while in a contaminated area.
9. The welding helmet may also be used without the front flip-up welding shield in place. If performing long term grinding or other operations where
a wide field of view and respiratory protection is necessary, the outer flip-up welding shield may be removed by:
a. Unscrewing the pivot knobs on both sides of the welding helmet.
NOTE: When the Pivot Knobs are removed, the internal head suspension will also be loose. Maintain control of the head suspension during this
operation so it does not fall out of the welding helmet.
b. Remove the outer welding shield and reattach the Pivot Knobs (Fig. 9).
10. Complete any final performance checks required according to the User Instructions for your Powered Air Purifying Respirator (PAPR) blower unit or
Supplied Air (SA) device before entering a contaminated area.
