M-444 Inner Shrouds (M-400 Series)

To remove inner shroud, unzip inner shroud from outer shroud and remove. To install inner shroud, align
the zipper parts on the inner and outer shroud and connect. Ensure inner shroud is completely zipped into
the outer shroud (Fig. 15).

M-116 and M-316 Airflow Deflectors

The M-116 (M-100 and M-200) and M-316 (M-300 and M-400) airflow deflectors are not intended to
be removed on a regular basis. They are designed to stay in the headgear until broken or damaged. To
replace broken parts, move the visor to the up (open) position. With the headgear upside down, remove
damaged or broken airflow deflector. Gently use a tool if necessary (e.g. plier). Install deflector by
snapping into place.

M-154 Replacement Forehead Seal (M-100 and M-200 Series)

- To remove forehead seal, lift visor frame into the up (open) position and unbutton the seal from its
attachment points on the suspension. Grasp the black gasket and slowly and gently pull straight out
in small sections, starting at one end and working around the gasket. Do not start in the middle of the
gasket as this may cause the gasket to rip or tear.
- To install forehead seal, grasp the black gasket and align with headgear according to Fig. 16a.
NOTE: The "shiny" side of the seal should be facing towards you (i.e. outwards) as you install the
seal. Press the gasket firmly into the groove in small sections. Both gasket ribs should be fully
inserted into the groove. Grasp fabric tab with button and fold over to inside of suspension. Attach
forehead seal button to head suspension (Fig. 16b).

M-354 Replacement Forehead Seal (M-300 Series)

The forehead seals are designed to stay in the headgear and are not intended to be removed until they
need replacement. Completely remove current seals before installing new ones. If needed, gently hand
scrape off any residue. Clean the surfaces with a respirator wipe or damp cloth and wipe dry with towel.
Ensure surfaces are completely clean and dry before installing new forehead seals. Install one seal at a
time. Peel off backing from seal. Hold seal in place in appropriate location with hand pressure for at least
5-10 seconds to ensure adhesion.

To install new gasket, align end with the edge of the groove in the bottom of visor frame. Press the gasket
firmly into the groove in small sections. Both gasket ribs should be fully inserted into the groove (Fig. 17).
